Mojo trait

OutputFusionTile

Trait for tile-based output fusion structs that provide custom store behavior for a TileTensor.

The tile analog of OutputFusion: store is terminal (owns the store and returns nothing), where ComputeOutputFusionTile.compute transforms a tile and returns it for the primary kernel to store.

Takes two copiers, both chosen by the calling kernel: copier loads any aux epilogue inputs (e.g. a broadcast bias) into local, and store_copier writes the transformed tile out to the output. Passing the store copier (rather than having the graph compiler synthesize one) keeps the copier choice with the kernel author.

Implemented traits​

AnyType, Copyable, ImplicitlyCopyable, ImplicitlyDeletable, Movable, RegisterPassable, TrivialRegisterPassable

Required methods​

__init__​

def __init__(out self, *, copy: Self)

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

Args:

  • ​copy (_Self): The value to copy.

Returns:

_Self

def __init__(out self, *, deinit move: Self)

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

Args:

  • ​move (_Self): The value to move.

Returns:

_Self

store​

def store[dtype: DType, rank: Int, LayoutType: TensorLayout, Copier: TileCopier, StoreCopier: TileCopier](self, tile_coords: IndexList[rank], copier: Copier, store_copier: StoreCopier, val: TileTensor[dtype, LayoutType, MutAnyOrigin])

Provided methods​

copy​

def copy(self) -> Self

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

Overriding this method is not allowed.

Returns:

_Self: A copy of this value.
