Mojo trait

SMemTileWriter

Base trait for tile writing mechanisms in matrix multiplication.

This trait defines the interface for writing tiles from shared memory to global memory, abstracting over different hardware mechanisms.

Implemented traits

AnyType, Copyable, ImplicitlyCopyable, ImplicitlyDestructible, Movable, RegisterPassable, TrivialRegisterPassable

Required methods

__init__

__init__(out self: _Self, *, copy: _Self)

Create a new instance of the value by copying an existing one.

Args:

  • copy (_Self): The value to copy.

Returns:

_Self

__init__(out self: _Self, *, deinit take: _Self)

Create a new instance of the value by moving the value of another.

Args:

  • take (_Self): The value to move.

Returns:

_Self

write_tile

write_tile(self: _Self, src: LayoutTensor[_Self._dtype, src.layout, MutAnyOrigin, address_space=AddressSpace.SHARED, element_layout=src.element_layout, layout_int_type=src.layout_int_type, linear_idx_type=src.linear_idx_type, masked=src.masked, alignment=128], coords: Tuple[Int, Int])

Write a tile from shared memory to global memory.

Args:

  • src (LayoutTensor): Source tile in shared memory (must be 128-byte aligned).
  • coords (Tuple): Tile coordinates (row, column) in the destination matrix.

Provided methods

copy

copy(self: _Self) -> _Self

Explicitly construct a copy of self, a convenience method for Self(copy=self) when the type is inconvenient to write out.

Returns:

_Self: A copy of this value.
