make_mma_load_layout(local_buf, matrix='A')¶

Create a layout function for storing MMA results into a fragment buffer. This layout is used in conjunction with inverse_mma_store_layout to map fragment indices to threads and local indices.

Parameters:
  • local_buf (tir.Buffer) – The local buffer representing a fragment of a matrix.

  • matrix (str)

Returns:

A fragment object that describes how threads and indices in local_buf are laid out.

Return type:

T.Fragment

Raises:

AssertionError – If local_buf is not detected to be a fragment buffer.

make_mma_store_layout(local_buf)¶

Create a layout function for storing MMA results into a fragment buffer. This layout is used in conjunction with inverse_mma_store_layout to map fragment indices to threads and local indices.

Parameters:

local_buf (tir.Buffer) – The local buffer representing a fragment of a matrix.

Returns:

A fragment object that describes how threads and indices in local_buf are laid out.

Return type:

T.Fragment

Raises:

AssertionError – If local_buf is not detected to be a fragment buffer.
