Mojo struct
StandardTilePayload
struct StandardTilePayload[a_type: DType, b_type: DType, a_shape: IndexList[Int(2)], b_shape: IndexList[Int(2)], num_pipeline_stages: Int]
Tile payload for standard matmul (A and B tiles).
Uses explicit dimensions for tile arrays. The tiles are stored as TileTensor with row_major layout. TileTensors are passed directly to TMA/MMA. at TMA/MMA boundaries.
Parameters
- a_type (
DType): Element type of the A operand tiles. - b_type (
DType): Element type of the B operand tiles. - a_shape (
IndexList[Int(2)]): A tile dimensions as(BM, BK). - b_shape (
IndexList[Int(2)]): B tile dimensions as(BN, BK). - num_pipeline_stages (
Int): Number of pipeline buffer stages.
Fields
- a_tiles (
StandardTilePayload[a_type, b_type, a_shape, b_shape, num_pipeline_stages].ATileArray): - b_tiles (
StandardTilePayload[a_type, b_type, a_shape, b_shape, num_pipeline_stages].BTileArray):
