173 implement device grouped gemm fixed nk for rdna4 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Proposed changes This PR adds an RDNA4 implementation of the device_grouped_gemm_fixed_nk instance library using for WMMA. The implementation is based on the existing DeviceGroupedGemm_Xdl_Fixed_NK design and reuses the same high-level structure, but replaces the XDL kernel with a WMMA-based one. It uses the GridwiseGemm_wmma_cshuffle_v3 kernel. At this stage, the focus is functional correctness and compatibility, not performance tuning. ## Technical Details - Device struct for grouped gemm fixed NK - Example code for the WMMA version - Unit tests for both new wmma implementation and the reference XDL code (previously missing) - Generic ck profiler interface with the purpose of calling unit tests. ## Checklist Please put an into the boxes that apply. You can also fill these out after creating the PR. If you're not sure, please don't hesitate to ask. - [x] I have added tests relevant to the introduced functionality, and the unit tests are passing locally - [x] I have added the test to REGRESSION_TESTS list defined at the top of CMakeLists.txt in tests/CMakeLists.txt, **IF** the test takes more than 30 seconds to run. - [ ] I have added inline documentation which enables the maintainers with understanding the motivation - [ ] I have removed the stale documentation which is no longer relevant after this pull request - [x] (If this change is user-facing) I have added release notes which provide the end users with a brief summary of the improvement from this pull request - [x] I have run on all changed files - [x] Any dependent changes have been merged ## Discussion If this is a relatively large or complex change, feel free to start a discussion by explaining why you chose the solution you did and what alternatives you considered
