• Set of unit tests that demonstrate the usage of sparse and blockscaled sparse Blackwell SM100 GEMM.
• A new Multi-head Latent Attention (MLA) for SM100 Blackwell architecture in CUTLASS example covers the flashMLA-like weight-absorbed decoding use-case.
• A new FMHA Backward kernel for SM100 Blackwell architecture extends CUTLASS example to show how the five backward pass MMAs can be fused into a single kernel to achieve high performance.
• A new distributed GEMM example for SM100 Blackwell architecture.
• Enhancement and new support of block-wise and group-wise GEMM for Hopper and Blackwell architectures:
  • Enhancement of blockwise GEMM for Hopper architecture.
  • Enhancement of groupwise GEMM for Hopper architecture.
  • Support for grouped GEMM with blockwise and groupwise scaling for Hopper architecture.
  • Support for grouped-wise GEMM in CUTLASS profiler.
  • Support for blockwise GEMM for Blackwell architecture.
  • Support for groupwise GEMM for Blackwell architecture.
  • Support for grouped GEMM with blockwise and groupwise scaling for Blackwell architecture.
• Added support for enhanced kernel performance search (auto-tuning) in CUTLASS profiler:
  • Sorting performance results by GFLOPs/second: Users can now sort the final performance report based on GFLOPs/second, making it easier to identify the most efficient kernels.
  • Exhaustive search for best kernel performance in GFLOPs/second: The profiler now searches for the best-performing kernel across a range of problem sizes, swizzle sizes, rasterization orders, and dynamic cluster configurations to maximize performance.
  • Performance search under a fixed GEMM shape: Enables exhaustive tuning within a fixed GEMM shape, exploring various kernel parameters to find the best configuration.
  • More detailed introductions and examples to leverage this feature can be found in profiler.md.
• Support void as the D element in sm100 kernel epilogues.
