rocWMMA 2.2.0 for ROCm 7.2.0

Added

• Added sample perf_i8gemm to demonstrate int8_t as matrix input data type
• Added support for the gfx1150 target

Changed

• Removed unnecessary const keyword to avoid compiler warnings
• rocWMMA has been moved into the new rocm-libraries "monorepo" repository (https://github.com/ROCm/rocm-libraries). This repository consolidates a number of separate ROCm libraries and shared components.
  • The repository migration requires a few changes to the CMake configuration of rocWMMA
  • The repository migration rquired the GTest dependency to be updated to v1.16.0

Resolved issues

• Skip invalid test configurations when using 'register file' LDS mapping
• Ensured transform functions in samples are only available on the device

rocWMMA 2.0.0 for ROCm 7.0.0

Added

• Added internal register layout transforms to support interleaved MMA layouts
• Added support for the gfx950 target
• Added mixed input bf8 / fp8 types for MMA support
• Added fragment scheduler API objects to embed thread block cooperation properties in fragments

Changed

• Augmented load / store / MMA internals with static loop unrolling
• rocWMMA mma_sync API now supports wave tile fragment sizes
• rocWMMA cooperative fragments are now expressed with fragment scheduler template arguments
• rocWMMA cooperative fragments now use the same base API as non-cooperative fragments
• rocWMMA cooperative fragments register usage footprint has been reduced
• rocWMMA fragments now support partial tile sizes with padding

Optimized

• Added internal flow control barriers to improve assembly code generation and overall performance
• Enabled interleaved layouts by default in MMA to improve overall performance

Removed

• Removed support for the gfx940 and gfx941 targets
• Removed the rocWMMA cooperative API
• Removed wave count template parameters from transforms APIs

Resolved issues

• Fixed a validation issue for small precision compute types < B32 on gfx9
• Fixed CMake validation of compiler support for bf8 / fp8 types
• Fixed linkage of rocwmma::synchronize_workgroup to inline
