Mojo struct
BlockwiseFP8TilePayload
struct BlockwiseFP8TilePayload[a_type: DType, b_type: DType, a_scales_type: DType, a_shape: IndexList[2], b_shape: IndexList[2], a_scales_shape: IndexList[2], num_pipeline_stages: Int]
Tile payload for blockwise FP8 matmul (A, B, A-scales tiles).
Unlike BlockScaledTilePayload, this only stores A-scales in SMEM. B-scales are read directly from global memory during the epilogue phase.
Fields
