Mojo trait

AsyncTileCopier

Trait for asynchronously copying a TileTensor between address spaces.

Distinct from TileCopier because async copies have semantics the synchronous trait cannot express: on NVIDIA the copy call only issues the transfer, and callers must commit it via async_copy_commit_group() and synchronize via async_copy_wait_all() or async_copy_wait_group() before reading the destination tile. Keeping the trait separate prevents code generic over TileCopier from silently accepting an async copier and producing reads that race the in-flight transfer, and gives the async path room to grow (e.g., explicit commit/wait members or multi-stage pipelining) as the async story is fleshed out.

Required 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])

Asynchronously copies src into dst.

The copy may not be complete when this call returns; callers must commit and synchronize before reading dst.

Args:

• ​dst (TileTensor[Storage=dst.Storage, address_space=_Self.dst_address_space, linear_idx_type=dst.linear_idx_type]): Destination tile in dst_address_space.
• ​src (TileTensor[Storage=src.Storage, address_space=_Self.src_address_space, linear_idx_type=src.linear_idx_type]): Source tile in src_address_space.
