* Remove old CK Tile Stream-K implementation
The original CK Stream-K implementation was based on old CK's Stream-K
block to C tile map. However, this implementation did not align with the
original Stream-K paper. Thus, we implemented a new tile partitioner and
associated Stream-K kernel, which was placed in the reboot namespace.
Now that the new Stream-K implementation is ready, this change removes
all artifacts of the old implementation. Specifically, the following
changes were made:
- Removes old Stream-K tile partitioner from CK Tile
- Removes the reboot namespace such that the new implementation resides
in the ck_tile namespace only.
- Adds tests for bf8 and fp8 using the new implementation
- Removes tests for the old implementation
- Remove the v2 suffix from the new CK Tile Tile Partitioner
derived classes.
- Updates Stream-K Kernel ops file to use /** commenting style.
* Remove v2 from tile partitioner validation function names
[ROCm/composable_kernel commit: 2e4b8a8fc4]
1. Enable grouped_gemm_quant and gemm_streamk on gfx12
- test_ck_tile_streamk_smoke is kept on gfx9, since it looks someone is still working on it.
2. Update warp tile size in grouped_gemm_quant and gemm_streamk unit test
3. Reduce gemm tile size to pass the build on gfx12 in test_gemm_streamk_reboot_types.hpp
[ROCm/composable_kernel commit: d2e32b4305]
* Wrap ck host utitlies in CK namespace.
The CK and CK-Tile source code bases are incompatible because CK is not properly using namespaces everywhere. In particular, we need to put hip_check_error in the ck namespace.
Move all functions in include/ck_/host_utility that were in global namespace into the ck namespace.
There may be additional namespace problems like this, and it's possible we'll have namespace clashes. But it is good design to properly guard our to code bases (CK and CKTile) so that they can both coexist. Moreover, estabilishing this compatiblity is essential if we are going to allow the builder to instantiate kernels from either template library.
* Add using declarations to test code.
After moving some of the untils into the ck namespace, most examples and a few tests had to be updated to recognize the new namespace declarations. We add using declarations to individual compute units for functions that were previously in the global namespace.
* Add using declarations to client examples.
[ROCm/composable_kernel commit: ad57f6ef0b]
* Use vectorized stores for dropout randvals
With no kPadSeqLenK the kernel uses 2 buffer_store_dwordx2 instead of
16 buffer_store_byte. This requires less registers and reduces spilling.
* Calculate dropout randvals for storing and applying only once
Even though it may add a small overhead when storing is not required,
it uses significantly less registers and hence no spilling.

* Refactor split-image implementation: simplify code and remove redundant variables
* Add padding debug output to split-image implementation
- Added debug prints for padding calculations in transform_conv_fwd_to_gemm.hpp
- Verified padding works correctly with all tests passing
* Fix sign comparison warning after rebase with origin/develop
- Cast blockIdX from unsigned to signed index_t for comparisons
- Integrated with new GetOutputTileIndex logic from upstream
- Updated to use amd_wave_read_first_lane instead of __builtin_amdgcn_readfirstlane
* Fix Split-N with groups bug and clean up unused parameters
- Fixed batch stride calculation to include G dimension for grouped convolutions
- When moving between batches in NHWGC/NWGC/NDHWGC layouts, need to account for all groups
- Removed unused multi-split parameters (we only support 2-way split)
- All tests now pass: G=1 with Split-N, G>1 with Split-N, G>1 without Split-N
* Implement recursive queue-based split-image detection and calculation
- Add LaunchKernelWithSplitIfNeeded() helper method in transform_conv_fwd_to_gemm.hpp
- Implement recursive binary splitting algorithm (10GB→5GB+5GB→...)
- Correctly handle odd dimensions (61→30+31)
- Calculate proper offsets for each split piece
- Update invoker to use split-image helper
Note: Split detection and calculation work correctly but kernel launching
for individual pieces requires kernel modification to handle different
spatial dimensions (unlike Split-N which uses blockIdx.z).
* WIP: Split-Image investigation - found architecture mismatch
- Split-N modifies N_ directly in transformer constructor
- Split-Image needs different approach due to varying dimensions
- Added split calculation logic for 1D and 2D convolutions
- Still facing memory issues when creating piece transformers
Key finding: Split-N uses blockIdx.z for parallel execution,
while Split-Image needs sequential execution of non-uniform pieces.
* Add 1D split-image implementation for grouped convolution (N=1 working)
Implements split-image for 1D convolution to handle large tensors that
exceed memory thresholds. This is a critical milestone with N=1 fully
working and tested.
Key Changes:
- Invoker: Add split-image logic that splits W dimension in half
- Transformer: Add SplitConvProblem helper for recursive splitting
- Calculate offsets for LEFT and RIGHT pieces
- Launch two kernels sequentially (LEFT then RIGHT)
Implementation Details:
- Binary split: divides W dimension by 2
- LEFT piece: W=0 to W/2, keeps left padding, removes right padding
- RIGHT piece: W/2 to W, removes left padding, keeps right padding
- Offset calculation accounts for stride, dilation, and padding
- Physical memory offset (no padding in memory)
Test Results (N=1):
✅ 94/94 tests passing
- Comprehensive tests: 36/36 (channels, padding, stride, dilation, filters, groups)
- Edge case tests: 31/31 (odd dimensions, extreme parameters, boundaries)
- Stress tests: 27/27 (maximum dimensions, up to 91.4 TFlops)
Known Limitations:
- Only works with N=1 (single batch)
- N>1 fails when split-image triggers (offset calculation issue with Split-N)
- Root cause: Split-N modifies N in transformer, but offset calculated in invoker
- Solution planned: Move offset calculation to transformer (next phase)
Files Modified:
- grouped_convolution_forward_invoker.hpp: Add split-image logic
- transform_conv_fwd_to_gemm.hpp: Add SplitConvProblem helper
This commit represents a stable, tested 1D split-image implementation
for N=1 cases. It's an important milestone before extending to N>1
and multi-dimensional splits.
* Add basic split-image implementation for 1D/2D/3D grouped convolution
This is a working baseline implementation that splits large spatial
dimensions to handle memory constraints.
Implementation:
- 1D: W-split for NWGC layout (36/36 tests passing)
- 2D: H-split for NHWGC layout (20/20 tests passing)
- 3D: D-split for NDHWGC layout (verified working)
Features:
- Binary split of outermost spatial dimension
- Sequential LEFT/RIGHT kernel launches
- Proper padding adjustment at split boundaries
- Offset calculation for pointer arithmetic
- Debug output for verification
Threshold: 100KB (configurable in transformer)
Known limitations:
- No safety checks for edge cases (to be added)
- Offset calculated before Split-N (incompatible with N>1, to be fixed)
- No recursive splitting for very large tensors
Next steps:
- Add safety checks (is_possible_to_split_*)
- Move offset calculation to transformer (after Split-N)
- Test with N>1 + split-image combination
* Refactor split-image to unified structure for 1D/2D/3D
Unified the three separate dimension-specific blocks into a single
common implementation with dimension-specific stride calculations.
Benefits:
- Reduced code from 636 → 348 lines (45% reduction)
- Eliminated code duplication
- Easier to maintain and extend
- Single source of truth for split logic
Implementation:
- Common: Binary split, offset calc, padding adjustment, kernel launch
- Dimension-specific: Stride calculation only
- 1D: stride = G * C
- 2D: stride = W_in * G * C
- 3D: stride = H_in * W_in * G * C
Test results (all passing):
- 1D: 36/36 tests ✅
- 2D: 20/20 tests ✅
- 3D: 28/28 tests ✅
- Total: 84/84 (100%)
All test scenarios verified:
- Varying channels, padding, stride, dilation
- Filter sizes (1x1 pointwise to 7x7)
- Multiple groups (G=1,2,4)
- Odd dimensions
- Complex combinations
* Add safety checks for split-image in all dimensions
Added is_possible_to_split safety checks to prevent crashes when
splitting is not feasible.
Safety checks verify:
1. Output dimension > 1 (can't split single element)
2. RIGHT piece starts after left padding
3. LEFT piece ends within input bounds
If checks fail, falls back to normal kernel launch.
Verified for all dimensions:
- 1D (W-split): Wo=1 case triggers fallback
- 2D (H-split): Ho=1 case triggers fallback
- 3D (D-split): Do=1 case triggers fallback
Original 84 tests still pass - they use normal configurations
that naturally satisfy safety conditions.
Safety checks protect against pathological edge cases with:
- Very small spatial dimensions
- Extreme stride/dilation combinations
- Invalid padding configurations
* Fix Split-N + Split-Image compatibility issue
Fixed critical bug where Split-N and Split-Image working together
caused ~50% incorrect results due to wrong batch stride calculation.
Problem:
- Batch stride was calculated using MODIFIED spatial dimensions
(e.g., W=50000 after split) instead of ORIGINAL dimensions (W=100000)
- Spatial offset was applied globally in invoker, not per-batch in kernel
- Each batch (blockIdx.z) got wrong memory offset
Solution:
1. Store spatial offset in kargs (don't apply to pointer in invoker)
2. Copy correct batch_stride from temp_kargs to left/right kargs
3. Apply formula in operator(): ptr = base + (batch × stride) + spatial_offset
Changes:
- grouped_convolution_forward_kernel.hpp:
* Added spatial_offset_in/out fields to KernelArgs
* Apply batch + spatial offset in operator()
- grouped_convolution_forward_invoker.hpp:
* Keep base pointer, store spatial offset in kargs
* Copy batch_stride from temp_kargs (has original dimensions)
- transform_conv_fwd_to_gemm.hpp:
* Add debug output for split-image calculation
Results:
- N=1 tests: 84/84 passing (100%)
- N>1 tests: Now all passing (previously ~50% errors)
- Tested: 1D, 2D, 3D with N=1,2,4,8,16,20
* Implement unified threshold for Split-N and Split-Image
This commit consolidates threshold management for both Split-N and
Split-Image operations into a single source of truth, eliminating
code duplication and fixing offset calculation issues.
Key Changes:
============
1. Transformer (transform_conv_fwd_to_gemm.hpp):
- Moved TwoGB constant to public section for unified access
- CalculateSplitImage() now takes no parameters
- Uses internal threshold: TwoGB / sizeof(CDataType)
- Calculates offsets using N_ (after Split-N) for correctness
2. Kernel (grouped_convolution_forward_kernel.hpp):
- GetSplitImageInfo() simplified to take no parameters
- Forwards to transformer's CalculateSplitImage()
- Clean interface with unified threshold internally
3. Invoker (grouped_convolution_forward_invoker.hpp):
- Removed redundant threshold calculation
- Simplified to call kargs.GetSplitImageInfo() with no params
- Clean early-return pattern (no unnecessary else blocks)
- Removed duplicate/dead code paths
Benefits:
=========
- Single source of truth: TwoGB defined once in transformer
- No parameter passing for threshold between components
- Correct offset calculation using N_ (post-Split-N)
- Cleaner code with no duplication
- All tests passing: 1D/2D/3D with various N values
Testing:
========
- Split-Image only (N=1, large spatial): PASS
- Split-N only (N>1, small spatial): PASS
- Both splits active (N>1, large spatial): PASS
- No splits (N=1, small spatial): PASS
- CPU verification correct for all scenarios
* Comment out outdated split-image code (SplitConvProblem/LaunchKernelWithSplitIfNeeded)
The old recursive queue-based implementation has been replaced by the
new CalculateSplitImage() method which is simpler and correctly handles
Split-N + Split-Image interaction.
Changes:
- Wrapped lines 381-1078 in #if 0...#endif
- Old methods: SplitConvProblem() and LaunchKernelWithSplitIfNeeded()
- Preserved for reference but disabled from compilation
- No functional changes - all tests still pass
The new implementation (CalculateSplitImage at line ~2163) provides:
- Correct offset calculation using N_ (after Split-N)
- Simpler binary split logic
- Better integration with unified threshold approach
* Implement recursive split-image with depth limit (MAX_DEPTH=10)
Changes:
- Add depth tracking to SplitPiece struct
- Implement two stopping conditions:
1. Piece size below threshold (optimal case)
2. Depth >= MAX_DEPTH (prevents infinite recursion)
- Remove MAX_PIECES limit in favor of depth-based control
- Support up to 2^10 = 1024 pieces with depth 10
This allows handling extreme tensor sizes while ensuring termination.
Pieces larger than threshold will still launch correctly if depth limit reached.
Tested with H=100 (4 levels), H=2000 (6 levels), H=4000 (9 levels) - all pass CPU verification.
* Summary of recursive split-image implementation:
- Recursive queue-based splitting with depth limit (MAX_DEPTH=10, up to 1024 pieces)
- Two stopping conditions: size below threshold OR max depth reached
- Cumulative offset tracking through all recursion levels
- LEFT piece inherits parent offset, RIGHT accumulates (parent + local)
- Per-batch spatial offset application in kernel operator()
- Batch stride uses original dimensions (before split)
- Works with Split-N: split-N first, then recursive split-image
- Handles odd dimensions, padding, stride, dilation correctly
- All 1D/2D/3D tests pass with CPU verification
* Add comment explaining MAX_DEPTH capacity for 2GB threshold
* Refactor: move recursive split-image logic to transformer
- Move LaunchWithRecursiveSplit() from invoker to transform_conv_fwd_to_gemm.hpp
- Simplify invoker from ~250 lines to ~140 lines (removed 110 lines of inline logic)
- Encapsulate SplitPiece struct and BFS splitting algorithm in transformer
- Remove unused includes (queue, vector) from invoker
- Add documentation comment for AreDescriptorsSmallerThan2GB()
- Improve code organization and reusability
- No performance overhead (static template function, compiler inlines)
- All tests passing with 2GB production threshold
* Apply clang-format-18 formatting
- Format invoker and transformer files with clang-format-18
- Fix brace placement and alignment
- No functional changes
* Fix clang-format-18 issues in forward kernel
- Remove extra blank lines
- Fix line wrapping for template calls
- Consolidate GetSplitImageInfo() to single line
* Update include/ck_tile/ops/grouped_convolution/utils/transform_conv_fwd_to_gemm.hpp

* Split-Image implementation with temporary fixed divider
- Implemented spatial dimension splitting (Split-Image) for large tensors
- Added piece-based coordinate transformation for 1D/2D/3D convolutions
- Integrated Split-N (batch splitting) with automatic threshold detection
- Fixed M dimension calculation to include batch: M = N × spatial_size
- Added spatial offset support in kernel arguments
- Verified 20/20 test cases passing for Split-Image alone
- Known issue: Split-N + Split-Image combination needs coordinate fix
Implementation Details:
- Split factors: 4 (1D), 4×4 (2D), 4×4×4 (3D) - temporary fixed values
- Batch strides properly calculated for NWGC/NHWGC/NDHWGC layouts
- Piece descriptors track spatial boundaries and block ranges
- No performance overhead for N=1 cases
* Fix 1D split-image padding issue with per-piece dimensions
- Store actual size per piece to handle non-uniform splits
- Remove dead code from transform utils
* Fix 2D/3D split-image with independent split factors per dimension
Problem: Single split factor caused non-uniform pieces when dimensions
didn't divide evenly. Result: 18/25 (72%) 2D padding combinations failed.
Solution: Independent split factor selection for W, H, D dimensions.
Each dimension gets optimal factor based on its own size.
Test Results:
- 1D: 42/42 pass (100%)
- 2D: 25/25 pass (100%)
- Total: 67/67 combinations verified
* Remove unused split-image struct fields
Cleanup of split-image implementation:

- These fields were declared but never used in the kernel
- Per-piece dimensions are already stored in pieces[] array
- Reduces struct size and improves code clarity
Tested: 1D/2D/3D convolutions with split-image, padding, stride all pass
* Refactor split-image invoker code for improved readability
- Extract piece calculation logic into calculate_piece lambda helper

* Refactor split-image code and remove debug prints
- Extract GPU kernel helper lambdas for better readability
- Remove all split-image debug print statements
- Set memory threshold to 2GB for production

- Add MAX_TOTAL_PIECES=64 limit to prevent segfault
- Move calculate_spatial_piece to library utils
- Add layout validation (NWGC, NHWGC, NDHWGC only)
- Fix hierarchical splitting to respect piece limits
- Add proper documentation and formatting
* Change split-image from runtime to compile-time branching
Response to @bartekxk review comment:
Convert 'if(kargs.num_spatial_pieces > 1)' to 'if constexpr(EnableSplitImage)'
Changes:
- Add EnableSplitImage template parameter to kernel
- Change runtime if to compile-time if constexpr
- Update invoker to instantiate kernel variants with true/false
Benefits:
- Eliminates runtime branching in GPU kernel
- Dead code elimination (each variant is smaller)
