Mojo module
grouped_block_scaled_smem
Shared memory layout for grouped block-scaled SM100 matmul.
Extends BlockScaledTileCore with tensormap descriptor storage for dynamic updates. Used by GroupedBlockScaledMatmulKernel for grouped GEMM with variable problem sizes.
Additional SMEM allocations:
- 5 TMA descriptors (A, B, SFA, SFB, C) at 128 bytes each = 640 bytes total
- Aligned to 128 bytes for TMA descriptor requirements
Tile storage is shared via BlockScaledTileCore from block_scaled_smem.mojo.
