Function Documentation

filter_cols()

void tlapack::starpu::filter_cols ( void *  father_interface, void *  child_interface, struct starpu_data_filter *  f, unsigned  id, unsigned  nparts  )

inlinenoexcept

StarPU filter to partition a matrix along the y (column) dimension.

If nparts does not divide the number of columns, the last submatrix contains the remainder.

Parameters

[in]	father_interface	starpu_matrix_interface of the matrix.
[out]	child_interface	starpu_matrix_interface of the submatrix.
[in]	f	unused.
[in]	id	index of the submatrix.
[in]	nparts	number of submatrices.

filter_ntiles()

void tlapack::starpu::filter_ntiles ( void *  father_interface, void *  child_interface, struct starpu_data_filter *  f, unsigned  id, STARPU_ATTRIBUTE_UNUSED unsigned  nparts  )

inlinenoexcept

StarPU filter to define a multiple submatrices of a non-tiled matrix.

Note

The submatrices shouldn't overlap.

Parameters

[in]	father_interface	starpu_matrix_interface of the matrix.
[out]	child_interface	starpu_matrix_interface of the submatrix.
[in]	f	array with indexes {row0, col0, nrows, ncols}. The size of f is 4 * nparts.
[in]	id	index of the submatrix.
[in]	nparts	unused.

filter_rows()

void tlapack::starpu::filter_rows ( void *  father_interface, void *  child_interface, STARPU_ATTRIBUTE_UNUSED struct starpu_data_filter *  f, unsigned  id, unsigned  nparts  )

inlinenoexcept

StarPU filter to partition a matrix along the x (row) dimension.

If nparts does not divide the number of rows, the last submatrix contains the remainder.

Parameters

[in]	father_interface	starpu_matrix_interface of the matrix.
[out]	child_interface	starpu_matrix_interface of the submatrix.
[in]	f	unused.
[in]	id	index of the submatrix.
[in]	nparts	number of submatrices.

filter_tile()

void tlapack::starpu::filter_tile ( void *  father_interface, void *  child_interface, struct starpu_data_filter *  f, STARPU_ATTRIBUTE_UNUSED unsigned  id, STARPU_ATTRIBUTE_UNUSED unsigned  nparts  )

inlinenoexcept

StarPU filter to define a single submatrix of a non-tiled matrix.

Parameters

[in]	father_interface	starpu_matrix_interface of the matrix.
[out]	child_interface	starpu_matrix_interface of the submatrix.
[in]	f	array with indexes {row0, col0, nrows, ncols}.
[in]	id	unused.
[in]	nparts	unused.
