SharedToLocalTileCopier
struct SharedToLocalTileCopier[thread_layout: Layout[thread_layout.shape_types, thread_layout.stride_types], *, thread_scope: ThreadScope = ThreadScope.BLOCK]
A TileCopier that moves a tile from shared memory into registers.
thread_layout is used as the warp layout. axis-based distribution
is not yet supported, and this copier currently only produces correct
data when src was populated without a swizzle; reading a swizzled
shared-memory tile into local memory is not yet supported.
Parameters
- thread_layout (
Layout[thread_layout.shape_types, thread_layout.stride_types]): Warp layout describing how threads are organized over the copy. - thread_scope (
ThreadScope): Scope at which thread operations are performed.

Methods
copy
copy[element_size: Int](self, dst: TileTensor[address_space=SharedToLocalTileCopier[thread_layout, thread_scope=thread_scope].dst_address_space, linear_idx_type=dst.linear_idx_type, element_size=element_size], src: TileTensor[address_space=SharedToLocalTileCopier[thread_layout, thread_scope=thread_scope].src_address_space, linear_idx_type=src.linear_idx_type, element_size=element_size])
Copies src in shared memory into dst in local memory.
Parameters:
- element_size (
Int): Number of scalar elements per logical element.
Args:
- dst (
TileTensor[address_space=SharedToLocalTileCopier[thread_layout, thread_scope=thread_scope].dst_address_space, linear_idx_type=dst.linear_idx_type, element_size=element_size]): Destination tile in local memory. - src (
TileTensor[address_space=SharedToLocalTileCopier[thread_layout, thread_scope=thread_scope].src_address_space, linear_idx_type=src.linear_idx_type, element_size=element_size]): Source tile in shared memory.
