When there are multiple workgroups contributing to a tile, when using
atomics, there may be round off error in cases where the accumulator
type is not the same as the C type. To compute an error tolerance for
test validation, the Stream-K Tile Partitioner has a function called
estimate_num_wgs_per_tile to estimate the number of workgroups per tile.
That said, this function only provides an estimate. In some cases for
DP+2TSK, the function returns 1 rather than the more accurate value of
2.
Thus, this change updates the estimate_num_wgs_per_tile function to
explicitely return the value of 2 in cases for DP+2TSK to ensure that we
have a better error tolerance to avoid test failures due to round-off
error.
* 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
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
* 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.
* 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.
* Reapply "[CK_TILE] Non-K Major from old CK to CK-Tile (#2442)" (#3017)
This reverts commit e4298e55c7.
* WIP
* take Y2 as the AK1/BK1 value, that is the 'vector size' after shuffle
* use get_n_lds_banks()
* clang-format
