- Parameters
-
[in] | d_temp_storage | Device-accessible allocation of temporary storage. When NULL, the required allocation size is written to temp_storage_bytes and no work is done. |
[in,out] | temp_storage_bytes | Reference to size in bytes of d_temp_storage allocation |
[in] | d_values | Pointer to the array of num_nonzeros values of the corresponding nonzero elements of matrix A. |
[in] | d_row_offsets | Pointer to the array of m + 1 offsets demarcating the start of every row in d_column_indices and d_values (with the final entry being equal to num_nonzeros ) |
[in] | d_column_indices | Pointer to the array of num_nonzeros column-indices of the corresponding nonzero elements of matrix A. (Indices are zero-valued.) |
[in] | d_vector_x | Pointer to the array of num_cols values corresponding to the dense input vector x |
[out] | d_vector_y | Pointer to the array of num_rows values corresponding to the dense output vector y |
[in] | num_rows | number of rows of matrix A. |
[in] | num_cols | number of columns of matrix A. |
[in] | num_nonzeros | number of nonzero elements of matrix A. |
[in] | stream | [optional] hip stream to launch kernels within. Default is stream0. |
[in] | debug_synchronous | [optional] Whether or not to synchronize the stream after every kernel launch to check for errors. May cause significant slowdown. Default is false . |
