DPCT1134#
Message#
The tool cannot deduce the consumer API (dpct::sparse::csrgemm) of this API,
and this API has 2 arguments depending on the 8th and the 12th parameters of the
consumer API. Please replace the 2 arguments tagged as dpct_placeholder with
the corresponding value.
Detailed Help#
The output of dpct::sparse::csrgemm_nnz is a number representing the NNZ
(number of non-zero). This number is usually used as the size for memory allocation
which will be used by consumer API dpct::sparse::csrgemm. The API
dpct::sparse::csrgemm_nnz has 2 arguments depending on the 8th and the 12th
parameters of the related consumer API dpct::sparse::csrgemm. The tool cannot
detect the relationship. Users need to manually fill in those 2 arguments.
Suggestions to Fix#
For example, this original CUDA* code:
1void bar(cusparseHandle_t handle, cusparseOperation_t trans_a,
2 cusparseMatDescr_t descr_a, int c_nnz, cusparseMatDescr_t descr_b,
3 cusparseMatDescr_t descr_c, const float *val_a_s, const int *row_ptr_a,
4 const int *col_ind_a, const float *val_b_s, const int *row_ptr_b,
5 const int *col_ind_b, float *val_c_s, int *row_ptr_c, int *col_ind_c) {
6 cusparseScsrgemm(handle, CUSPARSE_OPERATION_NON_TRANSPOSE,
7 CUSPARSE_OPERATION_NON_TRANSPOSE, 3, 4, 3, descr_a, 4,
8 val_a_s, row_ptr_a, col_ind_a, descr_b, 5, val_b_s,
9 row_ptr_b, col_ind_b, descr_c, val_c_s, row_ptr_c,
10 col_ind_c);
