Detailed Description

rocsparse_csr2gebsr_buffer_size returns the size of the temporary buffer that is required by rocsparse_csr2gebsr_nnz and rocsparse_Xcsr2gebsr(). The temporary storage buffer must be allocated by the user.

Note

This function is non-blocking and executed asynchronously with respect to the host. It can return before the actual computation has finished.

This routine supports execution in a hipGraph context.

Parameters

[in]	handle	- handle to the rocSPARSE library context queue.
[in]	dir	- direction that specifies whether to count non-zero elements by rocsparse_direction_row or by rocsparse_direction_column.
[in]	m	- number of rows of the sparse CSR matrix.
[in]	n	- number of columns of the sparse CSR matrix.
[in]	csr_descr	- descriptor of the sparse CSR matrix. Currently, only rocsparse_matrix_type_general is supported.
[in]	csr_val	- array of nnz elements containing the values of the sparse CSR matrix.
[in]	csr_row_ptr	- integer array containing m+1 elements that point to the start of each row of the CSR matrix.
[in]	csr_col_ind	- integer array of the column indices for each non-zero element in the CSR matrix.
[in]	row_block_dim	- the row block dimension of the general BSR matrix. Between 1 and m.
[in]	col_block_dim	- the col block dimension of the general BSR matrix. Between 1 and n.
[out]	buffer_size	- number of bytes of the temporary storage buffer required by rocsparse_csr2gebsr_nnz and rocsparse_Xcsr2gebsr().

Return values

rocsparse_status_success	the operation completed successfully.
rocsparse_status_invalid_handle	the library context was not initialized.
rocsparse_status_invalid_size	m, n, row_block_dim, or col_block_dim is invalid.
rocsparse_status_invalid_pointer	csr_val, csr_row_ptr, csr_col_ind, or buffer_size pointer is invalid.
