[CK dispatcher] - LGBM predict data_type FLOAT32->FLOAT64 in ml_heuristic (#8132) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary `ml_heuristic.hpp` calls `LGBM_BoosterPredictForMat(..., /*data_type=*/0, ...)` (`C_API_DTYPE_FLOAT32`) against a `std::array<double, NUM_FEATURES>` feature buffer. LightGBM reinterprets the 8-byte doubles as 4-byte floats → invalid predictions → the heuristic's argmax always tie-breaks to the first/smallest enumerated config. **Fix:** `data_type 0 → 1` (`C_API_DTYPE_FLOAT64`), matching the `double` buffer. After the fix, predictions vary and track real TFLOPS (the model correctly prefers larger tiles). ## Verification - The feature buffer `f` is `std::array<double, NUM_FEATURES>` (NUM_FEATURES = 72) → `f.data()` is a `double*`. - The changed `0` is the 3rd positional `data_type` argument (not `nrow`/`ncol`/`is_row_major`). One-line functional change. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> |

[CK TILE] Fix performance regression caused by Dispatcher codegen compiler flag. (#8019) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Motivation Currently CK Tile two codegen paths: CK Builder and CK Tile Dispatcher. The CK Tile Dispatcher codegen uses an additional compiler flag that is not present in the CK Builder codegen workflow. The additional compiler flag can cause performance regression for so instances as it disables relevant compiler optimizations. ## Technical Details Removed compiler flag `-mllvm -enable-noalias-to-md-conversion=0` from the CMakeLists.txt that creates instance library from Dispatcher codegen. ## Test Plan Required testing is contained in the CI/CD pipeline. ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests. |

[CK_TILE] Add host-side Pack-GQA optimization for FMHA forward (#6533) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [CK_TILE] Add host-side Pack-GQA optimization for FMHA forward ## Motivation Host-side Pack-GQA optimization for CK-Tile FMHA forward. Reshapes Q tensor from `[b, nhead_q, seqlen_q, d]` to `[b, nhead_kv, nhead_ratio * seqlen_q, d]` by adjusting strides, so grouped Q-heads sharing the same KV data are processed in a single tile. Zero kernel changes — runner-only. Phase 1: non-causal attention with GQA ratio packing. Phase 2: extends to dropout and split-kv paths, fixes stride edge cases. ## Technical Details Modified files (2): - `example/ck_tile/01_fmha/example_fmha_fwd.cpp` — Pack-GQA flag plumbing - `example/ck_tile/01_fmha/fmha_fwd_runner.hpp` — Q tensor reshape logic, stride adjustment for GQA ratio packing New files (1): - `example/ck_tile/01_fmha/test_pack_gqa_phase2.sh` — 53 test cases covering non-causal, dropout, split-kv, various GQA ratios ## Dependencies None — this PR is standalone. ## Test Plan - GPU validation on MI300X (gfx942, ROCm 6.4.1): - Command: `./build/bin/tile_example_fmha_fwd -b=2 -h=32 -h_k=8 -s=2048 -d=128 -prec=bf16 -mode=group -v=1 -warmup=1 -repeat=3` - GPU validation on MI350X (gfx950, ROCm 7.0), 53 parameterized test cases: - Command (GQA 4:1): `./build/bin/tile_example_fmha_fwd -b=2 -h=32 -h_k=8 -s=2048 -d=128 -prec=bf16 -mode=group -v=1 -warmup=1 -repeat=3` - Command (GQA 8:1): `./build/bin/tile_example_fmha_fwd -b=2 -h=64 -h_k=8 -s=2048 -d=128 -prec=bf16 -mode=group -v=1 -warmup=1 -repeat=3` - Command (decode): `./build/bin/tile_example_fmha_fwd -b=64 -h=32 -h_k=8 -s=1 -s_k=4096 -d=128 -prec=bf16 -mode=group -v=1 -warmup=1 -repeat=3` ## Test Result Benchmark results (MI350X, gfx950, ROCm 7.0): | Config | Without Pack | With Pack | Improvement | |--------|-------------|-----------|-------------| | GQA 4:1 prefill b=2 h=32 hk=8 s=2048 d=128 bf16 | 690.05 TFlops (0.199 ms) | 695.61 TFlops (0.198 ms) | +0.8% | | GQA 8:1 prefill b=2 h=64 hk=8 s=2048 d=128 bf16 | 706.25 TFlops (0.389 ms) | 729.35 TFlops (0.377 ms) | +3.3% | | GQA 8:1 decode b=64 h=32 hk=4 s_k=4096 d=128 bf16 | 305.20 GB/s (1.763 ms) | 1813.41 GB/s (0.297 ms) | **+5.9x** | | LLaMA-70B decode b=32 h=64 hk=8 s_k=4096 d=128 bf16 | 591.70 GB/s (0.909 ms) | 1820.65 GB/s (0.295 ms) | **+3.1x** | | MHA ratio=1 b=2 h=8 s=4096 d=128 bf16 | 695.16 TFlops | 702.72 TFlops | no regression | Benchmark results (MI300X, gfx942, ROCm 6.4.1): No regression on MI300X.

[CK_Tile] Add wmma_bf16f32_16x16x32_bf16 warp-gemm test (#8035) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Adds the warp-gemm unit test for `wmma_bf16f32_16x16x32_bf16`. **Stacked on #8028** (the API change) and based on its branch, so #8028 shows the isolated API diff and this PR shows just the test. ## Test gfx125-guarded `WmmaBf16f32.ResidualPrecisionContrast`: computes `Y_bf16 = X_bf16·W_bf16 + R_fp32` via `WarpGemm::mac_downconvert`, compares against an fp32 reference (within bf16 tolerance), and asserts it is at least as accurate as the bf16-accumulate path — i.e. it demonstrates the precision benefit of the fp32 accumulator (`C`) carried into the fused bf16 down-convert. Passes on gfx1250. |

[ck] Unify Build_CK and buildHipClangJob into buildAndTest (#8108) ## Motivation `projects/composablekernel/vars/ck.groovy` had two near-identical build functions, `buildHipClangJob` (lean: static checks, FMHA, tile-engine, conv) and `Build_CK` (main per-arch matrix). This removes the duplication and fixes a latent GitHub-status bug that lived in both. ## Technical Details - Merged both into one `buildAndTest(Map conf)` gated by an explicit `is_main_build` flag (default `false` = lean path; `true` adds the GPU check + arch-gated inductor/perf/hipTensor; only `runBuildCKAndTests` sets it). - Deleted the `Build_CK_and_Reboot` / `buildHipClangJobAndReboot` wrappers (they only logged and re-threw); all 13 call sites now call `buildAndTest` directly. - Widened the shared `catch` to `Exception` so build / image-pull / "GPU not found" failures report **failure** instead of leaving the check stuck **pending** (failing stages now go red). - Removed the dead `no_reboot` key. No change to what is built or tested. ## Test Plan - Jenkins linter on the `Jenkinsfile`. - One branch run covering both paths (per-arch matrix + lean stages), spot-checking gfx1250 and a nogpu stage. ## Test Result - Verified statically: no `buildHipClangJob*` / `Build_CK*` references remain; `buildAndTest` defined once, all call sites wired. - Pending: linter + branch run before merge. ## Submission Checklist - [ ] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests. |

[CK Tile] Stream-K RDNA Support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Motivation Currently, CK Tile Stream-K only supports CDNA architectures. This change adds Stream-K support on RDNA3/3.5 and RDNA4 architectures. ## Technical Details Stream-K currently has 3 reduction strategies: 1) atomics, 2) linear, and 3) tree. The linear and tree reductions require inter-workgroup communication to a global flags buffer and a global partials buffer. To ensure cache coherency, we use cache modifiers to skip cache levels that are not visible to all workgroups. On CDNA architectures, scalar load and scalar store instructions are available, which we use to read and write to the flags buffer with appropriate cache skipping modifiers. However, RDNA architectures do not support scalar store instructions, so workgroups must use a buffer store instruction to write to flags. Additionally, cache modifiers differ between CDNA and RDNA; they also differ between RDNA3 and RDNA4. Given this information, the main changes are as follows: - Added RDNA flag signaling: Use buffer store instructions for writing to global flags buffer - Add appropriate cache modifiers for reading and writing to flags and partials: - RDNA3 (gfx11): Use `glc | dlc` coherence flags - RDNA4 (gfx12): Use `DEVICE` coherence scope - SFINAE-guarded overloads: Added compile-time dispatch for `SignalStorePartialDone()` and `WaitStorePartialDone()` based on target architecture - RDNA alignment requirements: Increased flags buffer alignment from 128B to 256B due to RDNA cache line size **A note about the `amd_buffer_coherence_enum`:** - **Problem:** The `amd_buffer_coherence_enum` uses preprocessor conditionals (`#if defined(__gfx12__)`) to define architecture-specific values. Template specializations reference enum values from different architectures (e.g., `glc_dlc` for GFX11). Due to C++ two-phase name lookup, non-dependent names are resolved during template parsing regardless of which architecture is being compiled, causing compilation failures when referenced values do not exist in the active preprocessor branch. - **Temporary Solution**: Added compatibility enum values to each architecture block. For example, I added `glc_dlc` in the `__gfx12__` block. I will create a ticket to refactor this enum with a design that has better scalability and tries to avoid the use of preprocessor conditionals. ## Test Plan ### Summary gtests were added to test wmma variants of Stream-K. These tests were stressed tested locally on gfx11 and gfx12. ### More details This PR makes the following changes/additions to the Stream-K gtests: - Split tests into MFMA (CDNA) and WMMA (RDNA) variants - Added 16 WMMA kernel types: FP16/BF16/FP8/BF8 × Linear/Tree reduction - WMMA uses 16×16×16 wave tiles for RDNA (this is the only tile size supported on RDNA) - Fixed RDNA WGP mode: multiply multiProcessorCount by 2 for actual CU count - As described in [HIP documentation](https://rocm.docs.amd.com/projects/HIP/en/docs-7.2.0/doxygen/html/group___global_defs.html#ggacc0acd7b9bda126c6bb3dfd6e2796d7ca3ac50041beb59111a5c76edf03da0898), when in Workgroup Processor (WGP) mode, the value of `hipDeviceAttributeMultiprocessorCount` is half of CUs, because a single WGP contains two CUs. The default mode on RDNA is WGP mode, so when creating (M, N, K) instances for gtests using the CU count, we need to multiply the CU count by 2 to get the correct value. This is not needed in the kernel host code, because the occupancy ensures that overall `max_active_wgs` is correct. ## Test Result All tests pass locally. ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests. |

[rocm-libraries] ROCm/rocm-libraries#4798 (commit 0acaf5f)
Using named functors instead of lambdas ## Motivation Currently, in block-level GEMM pipelines, there is significant code repetition for prefetching and tail handling, where lambda functions create a unique instantiations at each call. This includes repeated static_for instantiations and large loops such as MRepeat. Each repetition results in additional instantiations, which increases compilation time and binary bloat. ## Technical Details Refactor repeated code blocks into named functors so the compiler can reuse already instantiated code instead of generating multiple copies. Scope of changes: 1. WMMAOPS pipeline internals: projects/composablekernel/include/ck/tensor_operation/gpu/block/blockwise_gemm_pipeline_wmmaops_base.hpp, projects/composablekernel/include/ck/tensor_operation/gpu/block/blockwise_gemm_pipeline_wmmaops_v1.hpp, projects/composablekernel/include/ck/tensor_operation/gpu/block/blockwise_gemm_pipeline_wmmaops_v3.hpp 2. XDLOPS and preshuffle pipeline variants across projects/composablekernel/include/ck/tensor_operation/gpu/block (v1/v2/v3/v4/v5, scale, dequant, gufusion, moe, mx, blockscale, skip-b-lds, dpp, xdlops) Shared functor file: projects/composablekernel/include/ck/utility/vector_load_functor.hpp ## Test Plan Note that the provided compilation traces by -ftime-trace do not report unnamed lambda instantiations, so a clear baseline for instantiation counts cannot be established. As a result, the impact of this change will be evaluated based on runtime performance rather than direct instantiation-count comparisons. ## Test Result The effects of this were timed by the compilation of a single HIP object through an example (grouped_gemm_wmma_splitk_fp16.cpp). The average user time and speedup of this using the average of 100 compilations is: - Mean compile time before the changes: 37.734 s - Mean compile time after: 32.087 s - Speedup: 17.6% Ran a full CK compilation on Alola with the following results: | Metric | Before (min) | After (min) | Absolute Reduction (min) | % Reduction | | ------ | ------------ | ----------- | ------------------------ | |

[rocm-libraries] ROCm/rocm-libraries#8009 (commit 26ab70d)
[CK Tile] Add WAVELET pipeline for forward grouped convolution (#8009) ## Motivation CK Tile forward grouped convolution trails classic CK on 3x3 convolutions whose output-channel count is not divisible by 8, where the narrow output store limits the compute CShuffle epilogue. This ports the WAVELET pipeline (added for backward-weight in #7937) to the forward kernel to close that gap. ## Technical Details - Kernel (`grouped_convolution_forward_kernel.hpp`): WAVELET load/math-wave wiring, mirroring the backward-weight implementation; the non-WAVELET path is unchanged. - Generator: implement `parse_native_fwd_instance`, the forward native-instance parser. - Registered WAVELET instances: profiler bf16 3 / fp16 5, tests 1 each. WAVELET requires input channels divisible by 8 (it does not apply to depthwise). The bf16/fp16 instance asymmetry is intentional and measured: the VecC=8 tiles never beat the compute pool in bf16 but win about 20% of divisible-by-8 3x3 shapes in fp16, so VecC=8 is registered for fp16 only. ## Test Plan - Correctness (CPU reference) for every registered profiler instance, across VecC variants. - Per-shape best-instance performance sweep over the 34 RetinaNet shapes (bf16) and a 200-shape cross-model sweep (bf16 and fp16), compared against classic CK. ## Test Result - Correctness: PASS for all instances. - RetinaNet (bf16, vs classic CK): faster on 28 of 34 shapes, geomean +19.5%; the not-divisible-by-8 shapes up to 3.7x. One 1x1 stride-2 shape stays ~20% behind classic CK, unrelated to WAVELET. - Cross-model (200 shapes): WAVELET wins 3x3 not-divisible-by-8 in both dtypes (up to 61% over the next-best compute instance); for divisible-by-8 3x3 it wins about 20% of shapes in fp16 (3-11%) and none in bf16. ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.

[CK Tile] Fix Stream-K flag store: wave-uniform SGPR address for scalar s_store/s_load (#8099) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Motivation Stream-K grouped-conv (and GEMM) kernels fail to assemble for some instances: the inline scalar flag store/load gets a VGPR address operand, which scalar-memory instructions reject (`invalid operand for instruction`). This blocks Stream-K instances from building. ## Technical Details - `StreamKReductionOps::{Signal,Wait}StorePartialDone` (shared by GEMM and conv, added in #5393) take `kargs` by `const&` and feed `kargs.workspace_ptr` / `cta_idx` into inline `s_store_dword`/`s_load_dword` with `"s"` constraints. For some instantiations the compiler can't keep the pointer wave-uniform and emits a VGPR address. - Fix: route the pointer and offset through `amd_wave_read_first_lane` so the scalar-memory address is a wave-uniform SGPR before the asm. Same instructions, no algorithm change. - Not arch-specific: the affected instance fails on gfx908/gfx90a/gfx942/gfx950 without the fix; whether the compiler spills to a VGPR depends on the instantiation (tile/warp/pipeline), not the target. ## Test Plan - Compile the previously-failing dispatcher instance for gfx908/gfx90a/gfx942/gfx950. - `test_ck_tile_grouped_conv_bwd_weight_streamk` on gfx942, gfx90a, gfx950 hardware. - gfx950 perf A/B (example, bf16/tree, 10 runs each) with vs without the change. ## Test Result - Failing instance now assembles on all four archs; previously failed on every one. - 30/30 conv Stream-K tests pass on gfx942, gfx90a, gfx950. - gfx950 perf delta -0.13% (within run-to-run noise) — no regression from the added readfirstlane on the cold flag path. ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.

[tile_engine] Integrate gemm_streamk into budget-based sampling system (#8079) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Motivation `gemm_streamk` was the only GEMM op not participating in the tile engine's budget-based sampling system. Without a budget cap, it would always generate its full feasible set, making build times unpredictable and inconsistent with the other ops. ## Technical Details - **CMake budget propagation** (`ops/gemm/CMakeLists.txt`): Added `gemm_streamk` to the active-ops detection loop so it receives a share of the sampling budget. Because `gemm_streamk` lives in a sibling subdirectory (`ops/gemm_streamk/`), its allocation is written via `CACHE STRING "" FORCE` to make the variable visible across the CMake directory boundary. - **Per-combo budget division** (`ops/gemm_streamk/CMakeLists.txt`, `ops/gemm/grouped_gemm/CMakeLists.txt`): Added the same per-combo `MAX_INSTANCES` division that exists in `gemm_universal` and `gemm_preshuffle`. The total budget is divided by `n_datatypes × n_layouts` before the inner `foreach` loop so that sampling fires independently per `(dtype, layout)` combo rather than acting as a single global cap. - **Sampling integration** (`gemm_streamk_instance_builder.py`): Added `_apply_sampling()` method to `GemmKernelBuilder`, mirroring the Sobol+LHS+maximin sampling used by other ops. New constructor parameters: `gpu_target`, `max_instances`, `seed`, `tier`, `manifest_path`. New CLI arguments: `--gpu_target`, `--max-instances`, `--seed`, `--tier`, `--manifest-path`. The `--gpu_target` argument is now also forwarded on the `--list_kernels` invocation. - **`GEMM_STREAMK_AXES`** (`sampling/feasible_set.py`): Defined as `GEMM_AXES + ["reduction_strategy"]` to account for the extra axis unique to stream-K. Added `reduction_strategy` to `CATEGORICAL_AXES`. - **Weight rebalancing** (`sampling/op_weights.json`): Allocated 10% weight to `gemm_streamk` by proportionally reducing `gemm_universal` (0.35 → 0.30) and `gemm_preshuffle` (0.30 → 0.25). Total remains 1.00. ## Test Plan - Configure with `TILE_ENGINE_SAMPLING_TIER=daily` and verify that `gemm_streamk` receives a non-zero budget allocation and that `GEMM_STREAMK_MAX_INSTANCES` is set correctly. - Configure with `TILE_ENGINE_SAMPLING_TIER=daily` across multiple `(dtype, layout)` combos and confirm per-combo budget = total / n_combos. - Configure with `-DGEMM_STREAMK_MAX_INSTANCES=50` explicit override and verify the override is respected (budget allocation skipped). - Verify `chosen_instances.json` manifest is written to the working path when tier is active. - Confirm `op_weights.json` weights still sum to 1.00. ## Test Result <!-- Briefly summarize test outcomes. --> ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests. |

[CK] [MIOPEN] Split convolution library by layout MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit # Split Composable Kernel convolution operations by data layout TLDR: 1. This is a reorganization of files, folders, and CMakeLists for convolution kernels and facilitates a splitting of the convolution library into layouts. 2. The speedup can range anywhere between 15-40% depending on the target architecture for miopen only builds of CK. For TheRock nightly builds of CK, which includes both miopen and hip tensor kernel instances, this constituted in a 10% decrease in compile time for gfx1100. ## Overview Based on https://github.com/ROCm/composable_kernel/pull/3010/ (except keeping 1 static library) ## What MIOpen Actually Uses MIOpen **exclusively uses: - **NHWGC** for all 2D convolutions - **NDHWGC** for all 3D convolutions This is because MIOpen's tensor descriptors natively use channel-last, group-aware formats. ## Key Changes ### 1. Layout-Based Directory Structure Reorganized convolution instance files from flat per-operation to hierarchical layout-based structure. For example: **Before:** grouped_conv2d_fwd/ ├── device_grouped_conv2d_fwd_xdl_nhwgc_*.cpp (MIOpen-required) ├── device_grouped_conv2d_fwd_xdl_gnhwc_*.cpp (optional) └── device_grouped_conv2d_fwd_xdl_ngchw_*.cpp (optional) **After:** grouped_conv2d_fwd/ ├── nhwgc/ ← MIOpen-required │ ├── xdl/device_grouped_conv2d_fwd_xdl_*.cpp │ └── wmma/device_grouped_conv2d_fwd_wmma_*.cpp ├── gnhwc/ ← Optional (excluded with MIOPEN_REQ_LIBS_ONLY) └── ngchw/ ← Optional (excluded with MIOPEN_REQ_LIBS_ONLY) ### 2. Preserved Umbrella Library As before, all convolution operations are consolidated into a single static `device_conv_operations` library: - Aggregates layout-specific instance object files via `ADD_CONV_LAYOUT_INSTANCES` macro - **Default build:** Includes all layouts (NHWGC + GNHWC + NGCHW + NDHWGC + GNDHWC + NGCDHW) - **MIOpen build (`MIOPEN_REQ_LIBS_ONLY=ON`):** Includes only NHWGC and NDHWGC layouts ### 3. Binary Size Reduction When building with `MIOPEN_REQ_LIBS_ONLY=ON`: **Layouts Included (26 targets):** - 7× NHWGC instances (2D operations + variants) - 19× NDHWGC instances (3D operations + variants) **Layouts Excluded (16 targets):** - 3× GNHWC instances (2D operations) - 3× NGCHW instances (2D operations) - 3× GNDHWC instances (3D operations) - 3× NGCDHW instances (3D operations) - 2× GNWC instances (1D operations) - 1× NWGC instance (1D operations) - 1× additional NHWGC instance (grouped_conv1d_fwd, not needed by MIOpen) This represents a **~38% reduction in instance targets** (16 excluded out of 42 total layout-specific targets). ### Testing - ✅ All existing CK tests link against the umbrella library - ✅ MIOpen links successfully with the reduced umbrella library - ✅ Profiler builds with all layout-specific targets explicitly listed Notes from the Author: Since this refactor moved most of the convolution files further into subdirectories, I concentrated on ensuring that no source files were excluded, including sharded sources: Targets are correctly migrated — no missing targets, no shard count mismatches. |

[CK_TILE] [QuantGEMM] Fix SplitK tail handling and other improvements (#7199) This pull request introduces improved and more robust split-K support for quantized GEMM. The main changes add runtime validation, utility functions for split-K batch calculations, pointer offset handling for split-K in grouped kernels, and enhanced support for various tensor layouts. The changes also improve error handling and provide more flexibility for runtime tail handling in split-K pipelines. **Split-K Support and Validation Enhancements:** * Added runtime validation to ensure `k_batch` is a positive integer and that split-K configurations do not produce empty final batches or mismatched pipeline tails, with detailed error messages and logging for misconfiguration. [[1]](diffhunk://#diff-d000149a681cd42bfb9947872c603e556cea26cbd7fd4f8f60afc6595d975871R1184-R1211) [[2]](diffhunk://#diff-d000149a681cd42bfb9947872c603e556cea26cbd7fd4f8f60afc6595d975871L1161-R1250) * Introduced utility functions `get_splitk_batch_k_read` and `get_splitk_last_batch_k` to compute per-batch K read sizes and handle split rounding, ensuring correct and consistent split-K batch partitioning. [[1]](diffhunk://#diff-d000149a681cd42bfb9947872c603e556cea26cbd7fd4f8f60afc6595d975871R206-R234) [[2]](diffhunk://#diff-635b89bdffa96b2b42f1632520cde36701d7d631e864185591f6b32f7645cf47L104-R107) [[3]](diffhunk://#diff-d000149a681cd42bfb9947872c603e556cea26cbd7fd4f8f60afc6595d975871L388-R417) [[4]](diffhunk://#diff-d000149a681cd42bfb9947872c603e556cea26cbd7fd4f8f60afc6595d975871L1161-R1250) * Changed the default value of `k_batch` in `QuantGemmHostArgs` to 1 (no split-K) for safer default behavior. **Pointer Offsets and Grouped Kernel Handling:** * Updated `QuantGroupedGemmKernel` to apply split-K per-batch offsets to all input pointers, mirroring the behavior of non-grouped kernels and ensuring correctness for split-K launches. * Modified AQ tensor view handling to correctly reflect the remaining K-groups from the split-K batch's offset position, improving accuracy for split-K in grouped kernels. **Pipeline and Layout Flexibility:** * Added support for runtime selection of split-K tail handling via a new template parameter `RuntimeSplitKTail_`, with new helper methods to dispatch GEMM pipelines accordingly.

[CK Tile] Async support preshuffle GEMM ## Motivation Add async support to existing preshuffle GEMM pipeline ## Technical Details Notes: the implementation avoids previous strategy of duplicating pipelines for async support and instead add a switch `Async` to the ops Problem to enable async pipeline. Then, integrate the async pipeline in the existing one. This allows to avoid code duplication and facilitate the integration of buffer load to lds in existing pipelines. In my opinion, it should be used also for other pipelines which don't support buffer load to lds yet and it would also be a good idea to refactor the existing async GEMM pipelines with the same approach. Summary: - integrate buffer load to lds in existing pipeline - add optimal tensor descriptors for vmem loading and lds reading. They are currently optimized for 16x16 wave tiles but they also work for 32x32 wave tiles. Optimizations for 32x32 wave tile requires different lds layout and it will be done in a follow-up issue - Add async config to examples - Add test (gfx950 only) ## Test Plan New test for gfx950 `test_ck_tile_gemm_pipeline_wp_async` ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests. |

[CK_Tile] Add wmma_bf16f32_16x16x32_bf16 via fused-downconvert override (#8028) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Adds `__builtin_amdgcn_wmma_bf16f32_16x16x32_bf16` (fp32 accumulate → bf16 output) to the CK Tile WMMA warp-gemm path. **API only** — the unit test is split into a stacked PR (#8035) so this API change can be reviewed in isolation. ## Changes (4 files) - **16-bit trait:** `wmma_intrinsic_downconvert` (calls the bf16f32 builtin — fp32 C in, bf16 C out) plus `COutDataType = bf16_t` / `COutVecType`. - **`WarpGemmAttributeWmmaImpl` / `WarpGemmAttributeWmma`:** `mac_downconvert(c_fp32, a, b)` (kTransC-aware) returning the bf16 C-output vector. - **`WarpGemmImpl`:** `mac_downconvert` tail handler producing a bf16 C-output tile from the fp32 accumulator tile, reusing `CWarpDstrEncoding` (output layout identical to the f32 C tile). Verified on gfx1250 (via the stacked test PR #8035): the test passes; the existing WMMA warp-gemm test is unaffected (additive change only). |

[CK] Load ck.groovy via Jenkins Shared Library
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
## Motivation
This allows the CI service to have a configuration source-of-truth
outside the PR under test, allowing rapid system changes. Bug fixes on
the develop branch propagate immediately to all pipelines that don't
override the parameter -- no rebase required.
A new `USE_CURRENT_BRANCH_FOR_CK_GROOVY` parameter lets contributors
test pipeline changes on their own branch without any extra
configuration.
## Technical Details
- `loadCk()` in the Jenkinsfile is updated to call
`library("ck@${branch}").ck.get()` instead of `checkout scm` + `load
"vars/ck.groovy"`. The `checkout scm` inside `loadCk()` is removed since
Jenkins now handles the library fetch internally.
- A `USE_CURRENT_BRANCH_FOR_CK_GROOVY` boolean parameter (default: off)
is added. When off, `ck.groovy` is always loaded from `develop` — all
normal PR builds are unaffected. When on, `ck.groovy` is loaded from the
current branch automatically via `env.CHANGE_BRANCH`, so contributors
testing pipeline changes just tick the box.
- `return this` is removed from the end of `ck.groovy`. This was
required by the `load` convention but is not needed (and can cause
errors) in a shared library context.
- `loadCk()` is kept at every call site rather than called once at the
top, preserving restart-from-stage safety — if a build is restarted from
a mid-pipeline stage, `ck` is still initialized correctly.
- The Jenkins Shared Library named `"ck"` must be registered in Jenkins
Global Pipeline Libraries
## Test Plan
1. Trigger "Build with Parameters" on the PR branch with
`USE_CURRENT_BRANCH_FOR_CK_GROOVY=true`
2. Verify "Determine CI Execution" stage completes and the library()
calls indicates the current branch
3. Verify "Static checks" stage completes.
4. Trigger a second build with `USE_CURRENT_BRANCH_FOR_CK_GROOVY=false`
(default) to confirm normal builds still load from `develop`.
## Test Result
Verified both paths. The develop library is loaded by default, the
branch library is loaded when the parameter is enabled.

[ck] Enforce ASCII-only C/C++ sources for hipRTC compatibility (#7829) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary CK source files must be compilable via **hipRTC (HIP runtime compilation)**, whose preprocessor does not accept non-ASCII bytes anywhere in a translation unit — **including in comments**. Bytes that are harmless under `hipcc` (em-dashes, smart quotes, multiplication signs, Greek letters, box-drawing glyphs, etc.) cause hipRTC to fail at preprocessing time. These regularly leak in via LLM-assisted authoring or copy/paste from formatted documents and silently break hipRTC paths that are not exercised by the default `hipcc`-based build matrix. This PR (a) cleans every existing violation (53 files) and (b) adds a pre-checkin gate so new violations are rejected before merge. ## File extensions covered Both the cleanup scan and the new Jenkins enforcement stage use the same predicate: ``` *.h *.hpp *.cpp *.h.in *.hpp.in *.cpp.in *.inc *.cl ``` (excluding `*/build/*` and `*/include/rapidjson/*`). This is a strict superset of the existing `Clang Format` stage's predicate — `*.inc` is added so test-fixture include files are also gated. The local pre-commit hook's `c++/inc` type filter covers the same set. ## Why no enforcement today CK is opted out of the rocm-libraries root `.pre-commit-config.yaml`, so the existing `pre-commit` workflow doesn't touch CK. The local CK `.pre-commit-config.yaml` only runs for developers who installed hooks. The **authoritative gate is therefore the new Jenkins stage** in this PR; the local hook is convenience. ## Commit layout (bisect-friendly) 1. `79798aa6261` — **`[ck] Convert reflect/ rendering to ASCII for hipRTC compatibility`** Behavior change, isolated. `TreeFormatter` swaps `├─ / └─ / │ ` for `|- / +- / | ` (3-col width preserved so alignment is unchanged). `conv_description.hpp` swaps `×` for `x` as the dimension separator. `test_conv_description.cpp` expected strings updated in lockstep so the snapshot test stays green. This is the only commit in the series with observable runtime impact. 2. `738fdb0d81c` — **`[ck] Strip non-ASCII bytes from C++ sources for hipRTC compatibility`** Mechanical text cleanup across 53 files. Replacements happen in comments or in `std::cout` strings that are not asserted on by any test. None of the 174 `.inc` files in the tree required edits, but they were in the scan's predicate so the enforcement stage's predicate is a superset of what was scanned. Full replacement table in the commit message. 3. `1d7cd8ba235` — **`[ck] Enforce ASCII-only C/C++ sources for hipRTC compatibility`** - New `projects/composablekernel/script/check_ascii_only.sh` (modeled on `check_copyright_year.sh`). - New entry in `projects/composablekernel/.pre-commit-config.yaml` under the local-hooks block (`types_or: [c++, inc]`). - New `ASCII Only Check` parallel stage in `projects/composablekernel/Jenkinsfile`'s `Static checks` block, mirroring the existing `Clang Format` stage but with `*.inc` added to the find predicate. Always-on, no `RUN_CPPCHECK` gate. The tree is buildable at every commit boundary. Commit 1 leaves 50 known violations; commit 2 leaves 0; commit 3 wires the gate. ## Demo Script output on a synthesized violation: ``` $ printf '// em-dash test \xe2\x80\x94 here\n' > /tmp/bad.cpp $ projects/composablekernel/script/check_ascii_only.sh /tmp/bad.cpp ERROR: /tmp/bad.cpp contains non-ASCII bytes: 1:// em-dash test — here Fix: replace with ASCII (em-dash -> --, smart quotes -> ", arrows -> ->, etc.) $ echo $? 1 ``` Full repo scan after the cleanup commits (note the `-name '*.inc'` clause): ``` $ cd projects/composablekernel && find . -type f \( -name '*.h' -o -name '*.hpp' -o -name '*.cpp' \ -o -name '*.h.in' -o -name '*.hpp.in' -o -name '*.cpp.in' -o -name '*.inc' -o -name '*.cl' \) \ -not -path '*/build/*' -not -path '*/include/rapidjson/*' -print0 \ | xargs -0 -P 8 -n 64 script/check_ascii_only.sh $ echo $? 0 ``` ## Test plan - [ ] Jenkins PR build: confirm new `Static checks -> ASCII Only Check` stage runs green over the full predicate (incl. `*.inc`) and existing `Clang Format` stage is unaffected. - [ ] `test_conv_description` passes against the ASCII tree-formatter output (touched in commit 1). - [ ] Local: `pre-commit run ascii-only-checker --all-files` runs cleanly after installing CK pre-commit hooks via `script/install_precommit.sh`. - [ ] Manually inject a non-ASCII byte in any `.cpp/.hpp/.inc` file, push: confirm Jenkins fails the new stage with a clear error. - [ ] Spot-check a representative subset of touched files under hipRTC compilation to confirm no remaining hipRTC-blocking content (optional, since the static byte check is a sufficient condition for hipRTC preprocessor acceptance on this dimension). 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

composablekernel: remove stray *.hpp.bk backup artifacts (#7974) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Four `*.hpp.bk` files were accidentally committed to `projects/composablekernel/`, likely as leftovers from a prior merge or conflict resolution. Each is an older snapshot of its `.hpp` counterpart — the canonical `.hpp` files are newer and contain the correct current content. ## Deleted files | File | vs. `.hpp` counterpart | |---|---| | `ck_tile/core/tensor/tile_window.hpp.bk` | Older version: uses legacy `bool isL1Cache`/`PrefetchL1` template params; missing `DataCachePrefetchKind`-based prefetch API and `data_cache_prefetch.hpp` include | | `ck_tile/core/tensor/load_tile_transpose.hpp.bk` | Older version: missing `#if defined(__gfx950__)` guard and `Quad` struct (~90 lines) for gfx1250 architecture | | `ck_tile/ops/gemm/warp/warp_gemm_dispatcher.hpp.bk` | Older version: missing `WmmaTag`, `IsScale16` template param, and several newer dispatcher specializations | | `ck_tile/ops/gemm_quant/block/block_universal_gemm_as_bs_bquant_cr.hpp.bk` | Older version: `KPackA`/`KPackB` (since renamed `KPack`); uses `static_ford` (since refactored to nested `static_for`) | ## Verification - No other `.bk` files exist in `projects/composablekernel/`. - No build scripts, CMake files, includes, or documentation reference these `.bk` files. - No `.hpp` files were modified. |

=?UTF-8?q?[CK=20TILE]=20Unification=20Work=20=E2=80=93=20?= =?UTF-8?q?More=20accurate=20tests=20for=20MmaPipelines=20(#6212)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Motivation This PR solves several issues: #### More accurate tests for MmaPipelines The current tests for the MmaPipelines (test_amdgcn_sparse_mma, test_amdgcn_wavewise_mma) use explicit input fragment vectors filled with 1s, and only check the output of a single lane. We should have tests that actually use the MmaPipelines with non-trivial input matrices and verify the complete output. Some other aspects of the current MmaPipelines tests that I noticed and deserve some attention: 1. There is sometimes iteration over K outside of the pipeline, which is then included in WaveTileK or FragK, which is not correct. We should remove it, move K iteration inside of the pipeline, or be more clear about this outer-K loop size and how it propagates downwards. 2. There is very tight coupling between the kernel, gtest code, and test_pipeline helper, requiring a lot of information and functions to be passed back and forth. 3. The test_pipeline helper is doing a bunch of register-related logic on the host (related to point 1) 4. Without this register logic the only thing it does is check the device, call the kernel, and check the output, but with a lot of boilerplate. #### Test helper for detecting target arch at HOST runtime There is a really apparent issue we faced while writing tests: Scenario: 1. Compile a test that supports both gfx950 and gfx1201 for gfx950 2. Run the test on a server that only has gfx1201 GPU Actual: Segmentation fault Expected: The test can correctly detect from HOST runtime that the DEVICE target_id was different and skips the test. Notes: The only way of detecting the COMPILER_TARGET_ID in the existing "arch" framework is launching a kernel and calling `get_compiler_target()` (so, from a DEVICE code). This will create a segmentation fault if the current arch differs from the target arch. To cope with this issue, we propose to export the compiler target(s) (note they can be many) through `projects/composablekernel/test/ck_tile/core/arch/CMakeLists.txt` and define a test helper to deal with such cases. #### Add composition support to Transforms We have a small number of Transforms which act on MmaOp input and output data, before and after the MmaOp call respectively. These are currently implemented to work on an MmaTile level, but in theory they are also supposed to work at a WaveTile level, i.e. after composition of multiple MmaTiles to create larger effective MNK dimensions. Currently the composed MmaTiles look like 2D C-style arrays of the individual MmaTile level register vectors (see WaveWiseMmaPipeline). The transforms should be able to take these and perform the proper transforms to the whole WaveTile at once. This might allow for better performing transformations. Note: This PR handles the SparseTransform case and if we don't end up doing scale as a transformation, there isn't really much left to do. If we end up having only the sparse transform as a non-trivial transform, then we could also consider removing the Transform framework. |

[CK Tile] Fix V6 pipeline applicability and split-image initialization (#7936) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Motivation After adding code generation via CK Tile Dispatcher, some fwd and bwd weight tests for CK Tile convolutions are failing. This PR introduced correct applicability checks and fixes the split-image parameter initialization such that non-applicable instances are not invoked during test execution and split-image instances are correctly initialized. ## Technical Details Investigation revealed two distinct problems 1. For bwd weight, the compute V3 uses prefetch of 3 distinct tiles, which works incorrectly when the number of K-slices addressed by the workgroup is 1. This occurs when a large split-K value is used for a problem that results in a small Gemm-K value. 2. For fwd direction, the current CK Profiler/test infrastructure doesn't initialize the split-image parameters for instance where split-image is enable. Uninitialized split-image values result in non-deterministic behavior where the tests might randomly fail. Fixed problem 1. by adding a check in `IsSupportedArgument` that marks the instance invalid if the `num_loops = ceil(GemmK / (k_batch * KPerBlock)) < 4` for V6 pipeline kernel instances. The check is compile-time eliminated for other kernels. Fixed problem 2. by adding initialization of split-image parameters when split-image is enabled. The default initialization corresponds to full image with no split, i.e., the number of splits is 1 and it has the size of the full image. Added unit tests for the added logic. ## Test Plan Running the following test suites cover the logic added in this PR - test_grouped_convnd_fwd_tile - test_ck_tile_grouped_conv_fwd - test_grouped_convnd_bwd_weight_tile - test_ck_tile_grouped_conv_bwd_weight All test suites above are included in the automated test runs. ## Test Result <!-- Briefly summarize test outcomes. --> ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests. |

[CK_TILE][FMHA] Optimize long-context decoding on gfx11/12 (#7500) ## Motivation Relevant issue: ROCM-22065 FMHA has less-than-optimal performance of long-context decoding (i.e. when seqlen_q = 1) on gfx11/12. This PR optimizes the splitkv pipeline and configs for such scenarios. ## Technical Details Optimizations applied in this PR: 1. use tiles with smaller M0 (16 vs 64), these tiles are used when seqlen_q <= 16 2. adapt qr_nwarp_sshuffle pipeline for gfx11, it allows to use more warps even for M0 = 16 (the qr pipeline parallelizes work between warps in M dim so with M0 = 16 it allows to use only 1 warp) 3. enable kMergeNumHeadGroupsSeqLenQ (an optimization that merges one group of heads in GQA) for all hdim values, not only 128 4. increase the number of splits (multiply by the number of head groups) if (3) is used 5. increase the number of splits for RDNAs (`multiProcessorCount` is the number of WGPs on RDNAs, not CUs, so it should be doubled to have meaning similar to CDNAs) Performance on gfx1151: | Case | develop (GB/s) | This PR (GB/s) | |:-------|-------:|-------:| | [fp16\|group\|bshd] b:1, h:32/32, s:1/45056, d:64/64 | 127.58 | 183.11 | | [fp16\|group\|bhsd] b:1, h:32/32, s:1/45056, d:64/64 | 153.64 | 215.02 | | [fp16\|group\|bshd] b:1, h:16/8, s:1/77184, d:128/128 | 120.51 | 225.76 | | [fp16\|group\|bhsd] b:1, h:16/8, s:1/77184, d:128/128 | 130.62 | 223.84 | | [fp16\|group\|bshd] b:1, h:32/32, s:1/9600, d:128/128 | 82.65 | 138.44 | | [fp16\|group\|bhsd] b:1, h:32/32, s:1/9600, d:128/128 | 105.75 | 220.45 | | [fp16\|group\|bshd] b:1, h:8/1, s:1/401024, d:256/256 | 16.27 | 187.89 | | [fp16\|group\|bhsd] b:1, h:8/1, s:1/401024, d:256/256 | 16.28 | 188.19 | ## Test Plan An additional test case is added to the exiting test.

[CK] Fix gfx950 AITER Sync Regressions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes three gfx950 regressions in the AITER downstream CI that surfaced after the internal/gfx1250 re-sync (ROCm/rocm-libraries#6978): > **Companion aiter PR:** ROCm/aiter#3392 — host-side adaptations (`Kernel::BlockSize()` `constexpr` drops, blockscale `KBatch=1` clamp) plus the CK submodule bump used to validate these fixes together. - **FlyDSL MoE AOT cache miss** — the AITER MoE tests run with `check_aot_cache=True` and fail on any FlyDSL JIT cache miss, but the CI never pre-compiles the FlyDSL MoE kernels, so gfx950 always misses. Pre-compile them at the start of the AITER test stage. - **`buffer.load.lds.v4i32` link error** — ROCm/rocm-libraries#6978 reintroduced a clang-version guard mapping `llvm.amdgcn.raw.buffer.load.lds` to a `.v4i32`-suffixed name. That name exists in no LLVM (the rsrc operand is a fixed, non-overloaded `<4 x i32>`, so the intrinsic is never type-mangled), so gfx950 4-DWORD direct-to-LDS (e.g. fp4 MoE bpreshuffle) fails to link with `lld: undefined symbol: llvm.amdgcn.raw.buffer.load.lds.v4i32`. Use the canonical plain name unconditionally. - **mixed-precision flatmm warp-GEMM call** — ROCm/rocm-libraries#6978 generalized the scaled `WarpGemmImpl::operator()` from a fixed `<index_t opselA, index_t opselB>` signature to a variadic `<typename... Params>` one and updated the `mx_flatmm` pipeline to pass the op-selectors as `OpSelA<>`/`OpSelB<>` types, but missed the mixed-precision flatmm pipeline (`F8xMXF4`/`F16xMXF4`), which still passed raw integer op-selectors. These no longer bind to `typename... Params` (`error: no matching member function for call to 'operator()'`), breaking compilation of the fp8/bf16 × fp4 cktile MoE gemm1 instances on gfx950 (aiter `test_moe_2stage`). Wrap the op-selectors in `OpSelA<>`/`OpSelB<>`. ## Changes - `Jenkinsfile`: pre-compile the FlyDSL MoE AOT cache (`python3 aiter/aot/flydsl/moe.py`) before the AITER tests. - `include/ck/utility/amd_buffer_addressing_builtins.hpp` and `include/ck_tile/core/arch/amd_buffer_addressing_builtins.hpp`: drop the `__clang_major__` guard and always use `__asm("llvm.amdgcn.raw.buffer.load.lds")`. The plain name is the canonical one for all sizes including the gfx950 16-byte form, as the upstream LLVM gfx950 tests confirm. - `include/ck_tile/ops/flatmm/pipeline/mixed_prec_flatmm_pipeline_agmem_bgmem_creg_v1.hpp`: wrap the warp-GEMM op-selectors in `OpSelA<>`/`OpSelB<>` at the five call sites, matching the `mx_flatmm` pipeline. ## Test plan Validated via CI. |

Replace nested static_for lambdas with compile-time search helper (#6696) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary - Add `sequence_find_value` and `find_in_tuple_of_sequences` compile-time search helpers with O(1) template depth - Replace nested `static_for` lambdas in `TensorDescriptor::GetTransformAndItsUpperDimension` and `InitializeElementSize` - Apply same optimizations to `TensorAdaptor` Supersedes #4287. Conflict-resolved rebase of ROCm/composable_kernel#3600 onto current develop. ## Motivation The `TensorDescriptor` and `TensorAdaptor` classes had excessive template instantiation from: 1. Nested `static_for` loops with lambdas creating unique closure types at every call site 2. `generate_tuple` with lambdas causing per-type instantiation overhead The new helpers use constexpr array lookup and pack expansion instead of recursive template patterns, achieving O(1) template depth. ## Results (`example_grouped_conv_fwd_xdl_fp16`, n=10, interleaved, `-j1`, `-ftime-trace`) | TU | Baseline (mean) | New (mean) | Delta | Wilcoxon p | Mann-Whitney p | |----|-----------------|------------|-------|-----------|---------------| | `grouped_conv_fwd_xdl_fp16` (host) | 14,886 ms | 13,353 ms | **-10.3%** | **0.002** | **0.0002** | | `grouped_conv_fwd_xdl_fp16` (device) | 27,762 ms | 25,629 ms | **-7.7%** | **0.002** | **0.0002** | | **Total (all TUs)** | **57,732 ms** | **54,030 ms** | **-6.4%** | | | Unrelated TUs (`device_memory`, `host_tensor`, `convolution_parameter`) show no significant difference (p > 0.3), serving as negative controls. ### Methodology - 10 interleaved runs (baseline₁, new₁, baseline₂, new₂, ...) on the same node to eliminate ordering/warmup bias - Wilcoxon signed-rank test (paired, non-parametric) and Mann-Whitney U test (unpaired) - Built with patched clang (LLVM 22) on ctr2-alola-compile-11, `-j1` for accurate per-TU timing - Raw data available in Slurm job 275230 results ## Test plan - [x] 11 unit tests added (5 for `sequence_find_value`, 6 for `find_in_tuple_of_sequences`) - [x] Compile-time benchmark with statistical significance (p < 0.01) - [ ] Full CI Tracking issue: #4229 |

[rocm-libraries] ROCm/rocm-libraries#7935 (commit 5c96097)
[CK] Allow skipping split-K C-buffer zero-init in xdl_cshuffle blockscale GEMM (#7935) Add a `skip_zero_init` flag (default false) to the Problem/Argument of the xdl_cshuffle block-scale GEMM device ops (multiple_d ab_scale and blockscale b-preshuffle). When the flag is set, the device invoker skips the internal hipMemsetAsync that zeroes p_c_grid before the KBatch > 1 split-K atomic-accumulation path. The flag is declared on the gridwise Problem struct (inherited by Argument), so it is visible on both the rotating-cache (arg_) and the normal (arg) launch paths in each device op. Why: callers that already pre-zero the output buffer otherwise pay for a redundant device-wide memset before split-K atomic accumulation. Gating the memset behind an opt-in flag lets such callers avoid the duplicate work. Because the flag defaults to false, every existing call site is unaffected and the observable behavior is unchanged. ## Motivation <!-- Explain the purpose of this PR and the goals it aims to achieve. --> ## Technical Details <!-- Explain the changes along with any relevant GitHub links. --> ## Test Plan <!-- Explain any relevant testing done to verify this PR. --> ## Test Result <!-- Briefly summarize test outcomes. --> ## Submission Checklist - [ ] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.

[rocm-libraries] ROCm/rocm-libraries#7937 (commit abe276d)
[CK Tile] Add conv Wavelet GEMM pipeline and bwd_weight instances (#7937) ## Motivation CK Tile had no pipeline competitive with old CK's wavelet on the RetinaNet K=36 C=256 3x3 conv bwd_weight class. This adds a wave-specialized "wavelet" GEMM pipeline so CK Tile has a competitive kernel for spatial small-K shapes. ## Technical Details - New wavelet GEMM pipeline (`gemm_pipeline_ag_bg_cr_wavelet.hpp`): workgroup split into math waves (LDS read + MFMA) and load waves (DRAM read + LDS write). - VGPR role-split: `operator()` has two top-level mutually-exclusive `is_math` branches so the allocator overlays both roles onto the same physical VGPRs, cutting arch VGPR ~33-40% and raising occupancy. Correctness depends on identical `block_sync_lds` counts on both arms plus a matching load-wave barrier stub in the epilogue (`cshuffle_epilogue.hpp`). - Kernel dispatch (`grouped_convolution_backward_weight_kernel.hpp`): `kIsWavelet` path, `LaunchBlockSize`, load-wave barrier stub. Uplift: wavelet is the fastest CK Tile pipeline on the RetinaNet K=36 C=256 3x3 family, beating the best non-wavelet CK Tile kernel by 10-27% (googlenet K=320 by 16-23%); the role-split roughly halves the parity gap vs old CK on the 13x13 fp16 shape. ## Test Plan - `ckProfiler grouped_conv_bwd_weight`, NHWGC layout, fp16/bf16, `split_k=all`, CPU verify on RetinaNet K=36 shapes (7x7, 13x13) and a broad 2D sweep. - Correctness: `-v=1` across `split_k` in {-1,1,2,4,8,16,32,64} (barrier-parity / deadlock check). - `test_grouped_convnd_bwd_weight` over the tests `.conf` wavelet instances. ## Test Result - All wavelet instances CPU-verify correct across the split-K sweep; no hangs (dual-arm barrier sequence matches). - Wavelet wins the RetinaNet K=36 C=256 3x3 family (10-27% over best non-wavelet CK Tile) and googlenet K=320 (16-23%); at parity-or-better vs old CK on the majority of spatial shapes. ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests. |

[CK] Extract Jenkinsfile helpers into vars/ck.groovy shared library (#7743) ## Motivation The CK Jenkinsfile is a 2,215-line monolith mixing helper function definitions with pipeline stage declarations. This makes it difficult to review, modify, or extend CI stages without wading through unrelated infrastructure code. ## Technical Details Extract all helper functions from the Jenkinsfile into vars/ck.groovy, loaded at runtime via ck = load "vars/ck.groovy" in the first stage. The Jenkinsfile is reduced from 2,215 lines to 810 lines containing only the pipeline structure. - 36 helper functions moved to ck.groovy with no logic changes - 10 new stage-wrapper functions (runBuildCKAndTests, runTileEngineGemmTests, runClangFormat, etc.) extract inline environment{}/steps{} business logic from stages, eliminating the MethodTooLargeException caused by CPS-transformed shell strings exceeding the JVM 64KB bytecode limit - All ck. method calls in steps{} blocks wrapped in script{} as required by Jenkins Declarative Pipeline - rocmnode() remains in the Jenkinsfile (needed for agent{} labels before ck is loaded) - CRON_SETTINGS / POLL_SPEC remain in the Jenkinsfile (triggers{} evaluates at parse time before any workspace is available) - No stage names changed ## Test Plan - Jenkinsfile validated against the Jenkins Pipeline Linter (/pipeline-model-converter/validate) - All 35 shared helper functions diffed line-by-line against develop to verify no regressions - Merge from develop incorporated and verified (gfx1250 stage, ROCm 7.13 default, cmake_build updates) ## Test Result - Linter: passes - Function diff vs develop: all 35 functions match exactly - Awaiting Jenkins run to confirm end-to-end stage execution ## Submission Checklist - [ x ] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests. |

[CK_TILE] Fix conditional rescale numerical instability in FMHA forward (#6498) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [CK_TILE] Fix conditional rescale numerical instability in FMHA forward ## Motivation Fix numerical instability in the conditional O-accumulator rescaling optimization for CK-Tile FMHA forward (FlashAttention-4, Algorithm 6, Eq. 6). The conditional rescale optimization skips the expensive O-accumulator rescale when the running row-max shift is within a threshold (tau = log2(256) = 8.0). The original implementation had a bug: attention weights P were computed in the `m_new` reference frame before the skip/rescale decision. In the skip branch, `m` was reverted to `m_old`, but P remained in the `m_new` frame, causing incorrect softmax normalization. This fix introduces a `p_row_correction` factor: in the skip branch, P is multiplied by `exp2(m_new - m_old)` to bring it back to the `m_old` reference frame. - **Correctness:** Fixes broken inference on long sequences where running-max drift causes exp2 overflow (observed as degraded image quality on MI350X Flux2 generation) - **Performance:** Neutral to +4% depending on workload shape ## Technical Details 6 pipeline header files (same pattern in each): - `block_fmha_pipeline_qr_ks_vs.hpp` - `block_fmha_pipeline_qr_ks_vs_async.hpp` - `block_fmha_pipeline_qr_ks_vs_async_trload.hpp` - `block_fmha_pipeline_qr_ks_vs_fp8.hpp` - `block_fmha_pipeline_qr_ks_vs_whole_k_prefetch.hpp` - `block_fmha_pipeline_qs_ks_vs.hpp` In each file: - Lower threshold from 10.0 to 8.0 (tau = log2(256)) - Add `p_row_correction` distributed tensor initialized to 1.0 - Rescale branch: standard rescale of O_acc and l; correction = 1.0 - Skip branch: compute correction = exp2(-acc_scale_log2), update l, revert m, store correction - New `p_spans` sweep applies per-row correction to `p_compute` before P*V GEMM - Move P-to-PDataType cast to after correction sweep ## Dependencies None — this PR is standalone. ## Test Plan - GPU validation on MI300X (gfx942, ROCm 6.4.1): - Command: `./build/bin/tile_example_fmha_fwd -b=2 -h=8 -s=4096 -d=128 -prec=bf16 -v=1 -warmup=1 -repeat=3` - GPU validation on MI350X (gfx950, ROCm 7.0): - Command: `./build/bin/tile_example_fmha_fwd -b=2 -h=8 -s=4096 -d=128 -prec=bf16 -v=1 -warmup=1 -repeat=3` - Command: `./build/bin/tile_example_fmha_fwd -b=2 -h=8 -s=4096 -d=128 -prec=fp16 -v=1 -warmup=1 -repeat=3` ## Test Result Accuracy vs FP32 reference (MI350X, gfx950): | Shape | max_diff | mean_diff | |-------|----------|-----------| | B=1 H=24 M=4096 K=128 bf16 | 9.1e-4 | 4.6e-5 | | B=4 H=32 M=4096 K=128 bf16 | 9.9e-4 | 4.6e-5 | | B=1 H=24 M=4096 K=128 fp16 | 1.2e-4 | 9.0e-6 | Performance (MI350X, gfx950, ROCm 7.0): | Shape | FA4 (TFlops) | Always-rescale (TFlops) | Delta | |-------|-------------|------------------------|-------| | B=1 H=24 M=4096 K=128 bf16 | 425.9 | 428.5 | neutral | | B=2 H=8 M=2048 K=256 bf16 | 513.9 | 509.0 | +1.0% | | B=1 H=64 M=2048 K=64 bf16 | 481.7 | 464.3 | +3.7% | Benchmark results (MI300X, gfx942, ROCm 6.4.1): No regression on MI300X.

[CK_TILE] Use gfx11 float buffer atomics in FMHA Bwd ## Motivation FlashAttention CK backward on gfx11 can hit out-of-bounds/tail writes in the dQ accumulator atomic-add path when sequence rows are padded at the tile level but not marked invalid in the DQDKDV main tensor view. With the generic global atomic fallback, an incorrectly-valid tail element can issue an actual pointer-based `atomicAdd`. With the buffer atomic path, the write is issued through a buffer resource with bounds information and follows the same backend already used by gfx9/gfx12. This fixes the gfx11 FMHA BWD failure without changing the gfx11 default for unrelated CK Tile kernels. ## Technical Details This PR enables the existing CK Tile AMD buffer float atomic-add path only for generated FMHA BWD gfx11 translation units. gfx11 normally uses the generic global atomic fallback for floating-point `buffer_view::atomic_add`. That fallback performs the atomic through a raw computed pointer and depends on the software validity predicate to avoid invalid elements. In FMHA BWD dQ accumulation, padded tail rows can reach this path, so using the buffer atomic backend is safer: it uses a buffer resource with base pointer, bounds information, and an element offset, matching the backend already used by gfx9/gfx12. Enabling `CK_TILE_USE_AMD_BUFFER_ATOMIC_ADD_FLOAT` globally for gfx11 is too broad and can break unrelated gfx11 CK builds such as GEMM. Instead, `config.hpp` now preserves an explicitly pre-defined `CK_TILE_USE_AMD_BUFFER_ATOMIC_ADD_FLOAT`, while keeping the existing default disabled for gfx11. ## Test Plan Validated the change with the FlashAttention CK full test suite with backward pass enabled on gfx11. pytest -q -s tests/test_flash_attn_ck.py ## Test Result FlashAttention CK gfx11 test result: 260680 passed, 152076 skipped ## Submission Checklist - [ ] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.

[CK_TILE] Fix Stream-K k_size calculation ## Motivation In a recent benchmarking task for CK Tile Stream-K algorithm, we identified that certain instances segfault. This change works to fix the bug and adds necessary regression tests. ## Technical Details The StreamK kernel constructs tensor views using a `k_size` parameter that determines how much of the K dimension to process in each iteration. Previously, this was calculated as: ```cpp index_t k_size = num_loop_sk * TilePartitioner::KPerBlock; ``` This calculation assumes all macro tiles along K are exactly `KPerBlock` in size. However, when `K % KPerBlock != 0`, the final macro tile along K has a remainder size of `K % KPerBlock`, not a full `KPerBlock` (see the figure below): <img width="961" height="488" alt="image" src="https://github.com/user-attachments/assets/3e1cceed-5dcd-4980-8b02-cee24eecf262" /> With the old code, a workgroup working with the `MPerBlock x (K % KPerBlock)` tile in A and B risk accessing illegal memory. Hence, this change ensures that when `K % KPerBlock != 0`, workgroups processing iterations that include the final macro-tile along K calculate the correct `k_size` based on the remainder rather than assuming a full `KPerBlock`. ## Test Plan I added the following tests: 1. Unit tests added for the Stream-K Tile Partitioner: - `StreamKTilePartitionerBaseGetKSize/NoRemainderTiles` - validates full tiles - `StreamKTilePartitionerBaseGetKSize/RemainderTiles` - validates remainder handling 2. Regression tests that test a case where `K % KPerBlock != 0` ## Test Result Tests passed locally on gfx90a, gfx942, and gfx950. ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests. |

ck_tile: add FillUniformScaleDistribution and fix MX GEMM scale init (#7724) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary ### Problem MX GEMM pipeline tests were passing vacuously: scale bytes were drawn from a fixed range (40–60) which, for e8m0, maps to scales ≈ 10⁻²⁷ — far below FP16 min denorm. Both GPU and CPU produced all-zero outputs, so numerical checks passed without exercising the GEMM. ### Changes **`include/ck_tile/host/fill.hpp`** — new `FillUniformScaleDistribution<ScaleType>` functor - Accepts human-readable float bounds and maps them to the raw byte range of any ExMy scale type (e8m0, e4m3, e5m3) by re-centering the IEEE 754 exponent into the type's bias space - Sampling is uniform over raw bytes → uniform over representable values - Fixes left-shift UB: uses multiplication instead of `<< mant_bits` to avoid shifting negative signed integers (C++17 UB) - Adds `assert(min_r <= max_r)` to catch inverted-range UB when both bounds exceed the type's representable range - Provides default member values (0.125f, 2.0f) and `std::optional` seed consistent with sibling fillers - `/** */` Doxygen style with `@note` on snapping asymmetry **`test/ck_tile/gemm_mx/test_mx_gemm_pipeline_util.hpp`** — fix scale initialization - Replace manual byte-range distribution with `FillUniformScaleDistribution<>{0.125f, 2.0f}` - Use distinct seeds for scale_a (11941) and scale_b (11943) to avoid correlated scale tensors that were causing 60 test failures for fp4+e5m3/e4m3 combinations **`test/ck_tile/utility/test_fill.cpp`** — new unit tests for `FillUniformScaleDistribution` - 16 typed tests across e8m0, e4m3, e5m3: validity, range, reproducibility, coverage, snapping, stress, nullopt seed, and range overload - Test helper `expected_raw_range` mirrors implementation clamping exactly |
