Mojo struct
ScalesLoader
struct ScalesLoader[tma_origin: ImmutOrigin, dtype: DType, tile_layout: TensorLayout, desc_layout: TensorLayout = tile_layout, /, *, cta_group: Int]
TMA scales loader parameterized on new Layout types.
Uses TmaOpType to derive the TMATensorTile type from new Layout. Uses async_copy (no multicast). Coordinate order is (row_coord, k_coord) matching scales tensor layout.

comptime members
TmaOp
comptime TmaOp = TMATensorTile[dtype, tile_layout.rank, _to_index_list[tile_layout](), _to_index_list[tile_layout.rank, desc_layout]()]
TmaOpPtr
comptime TmaOpPtr = Pointer[ScalesLoader[tma_origin, dtype, tile_layout, desc_layout, cta_group=cta_group].TmaOp, tma_origin]
Methods
__init__
__init__[tma_op_type: AnyType](tma_op: Pointer[tma_op_type, tma_origin]) -> Self
Accepts any TMA pointer. Rebinds to the loader's derived type.
load
load[LayoutType: TensorLayout](self, dest: TileTensor[dtype, LayoutType, MutAnyOrigin, address_space=AddressSpace.SHARED], ref[AddressSpace._value] barrier: SharedMemBarrier, row_coord: Int, k_coord: Int)
Load scales using TMA async copy.
