Mojo struct
BlockwiseFP8TileStorage
struct BlockwiseFP8TileStorage[a_type: DType, b_type: DType, c_type: DType, a_scales_type: DType, a_shape: IndexList[2], b_shape: IndexList[2], c_dim0: Int, c_dim1: Int, a_scales_shape: IndexList[2], num_pipeline_stages: Int, num_output_stages: Int]
Storage for blockwise FP8 matmul tiles (A, B, C, A-scales).
Single source of truth for blockwise FP8 tile arrays and storage. B-scales are read directly from global memory during epilogue.
All tiles use TileTensor natively. LayoutTensor conversion is kept for SMemEpilogueWriter compatibility.
IMPORTANT: Field order preserves SMEM layout compatibility: a, b, c, a_scales.
Parameters
- a_type (
DType): Data type for A matrix tiles. - b_type (
DType): Data type for B matrix tiles. - c_type (
DType): Data type for C matrix tiles. - a_scales_type (
DType): Data type for A scale tiles. - a_shape (
IndexList[2]): Tile shape for A tiles as (rows, cols). - b_shape (
IndexList[2]): Tile shape for B tiles as (rows, cols). - c_dim0 (
Int): First dimension for C tiles (OutputM). - c_dim1 (
Int): Second dimension for C tiles (OutputN). - a_scales_shape (
IndexList[2]): Tile shape for A scale tiles as (rows, cols). - num_pipeline_stages (
Int): Number of input pipeline stages. - num_output_stages (
Int): Number of output pipeline stages.
