Mojo struct
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.

comptime members
dst_address_space
comptime dst_address_space = AddressSpace.LOCAL

src_address_space
comptime src_address_space = AddressSpace.SHARED
Source AddressSpace this copier reads from.
Methods
copy
def copy(self, dst: TileTensor[Storage=dst.Storage, address_space=Self.dst_address_space, linear_idx_type=dst.linear_idx_type], src: TileTensor[Storage=src.Storage, address_space=Self.src_address_space, linear_idx_type=src.linear_idx_type])
Copies src in shared memory into dst in local memory.
Args:
- dst (
TileTensor[Storage=dst.Storage, address_space=Self.dst_address_space, linear_idx_type=dst.linear_idx_type]): Destination tile in local memory. - src (
TileTensor[Storage=src.Storage, address_space=Self.src_address_space, linear_idx_type=src.linear_idx_type]): Source tile in shared memory.
