Detailed Description

rocsparse_prune_dense2csr_by_percentage_buffer_size returns the size of the temporary buffer that is required by rocsparse_Xprune_dense2csr_nnz_by_percentage() and rocsparse_Xprune_dense2csr_by_percentage(). 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]	m	- number of rows of the dense matrix A.
[in]	n	- number of columns of the dense matrix A.
[in]	A	- array of dimensions (lda, n).
[in]	lda	- leading dimension of dense array A.
[in]	percentage	- percentage>=0 and percentage<=100.
[in]	descr	- the descriptor of the dense matrix A. The supported matrix type is rocsparse_matrix_type_general and also any valid value of the rocsparse_index_base.
[in]	csr_val	- array of nnz ( = csr_row_ptr[m] - csr_row_ptr[0] ) non-zero elements of matrix A.
[in]	csr_row_ptr	- integer array of m+1 elements that contains the start of every row and the end of the last row plus one.
[in]	csr_col_ind	- integer array of nnz ( = csr_row_ptr[m] - csr_row_ptr[0] ) column indices of the non-zero elements of matrix A.
[in]	myInfo	- prune information structure.
[out]	buffer_size	- number of bytes of the temporary storage buffer required by rocsparse_Xprune_dense2csr_nnz_by_percentage() and rocsparse_Xprune_dense2csr_by_percentage().

Return values

rocsparse_status_success	the operation completed successfully.
rocsparse_status_invalid_handle	the library context was not initialized.
rocsparse_status_invalid_pointer	buffer_size pointer is invalid.
rocsparse_status_internal_error	an internal error occurred.
