LocalToGenericTileCopier
struct LocalToGenericTileCopier[thread_layout: Layout[thread_layout.shape_types, thread_layout.stride_types], *, num_threads: Int = thread_layout.size(), thread_scope: ThreadScope = ThreadScope.BLOCK]
A TileCopier that moves a tile from registers into generic memory.
Parameters
- thread_layout (
Layout[thread_layout.shape_types, thread_layout.stride_types]): Layout describing how threads are organized over the copy. - num_threads (
Int): Total number of threads in the thread block. Threads beyondthread_layout.size()do not participate. - thread_scope (
ThreadScope): Scope at which thread operations are performed.

Methods
copy
copy[element_size: Int](self, dst: TileTensor[linear_idx_type=dst.linear_idx_type, element_size=element_size], src: TileTensor[address_space=LocalToGenericTileCopier[thread_layout, num_threads=num_threads, thread_scope=thread_scope].src_address_space, linear_idx_type=src.linear_idx_type, element_size=element_size])
Copies src in local memory into dst in generic memory.
Masked bounds checking is not supported.
Parameters:
- element_size (
Int): Number of scalar elements per logical element.
Args:
- dst (
TileTensor[linear_idx_type=dst.linear_idx_type, element_size=element_size]): Destination tile in generic memory. - src (
TileTensor[address_space=LocalToGenericTileCopier[thread_layout, num_threads=num_threads, thread_scope=thread_scope].src_address_space, linear_idx_type=src.linear_idx_type, element_size=element_size]): Source tile in local memory.
