This matrix type is identical to MATSEQAIJCUSPARSE when constructed with a single process communicator, and MATMPIAIJCUSPARSE otherwise. As a result, for single process communicators, MatSeqAIJSetPreallocation is supported, and similarly MatMPIAIJSetPreallocation is supported for communicators controlling multiple processes. It is recommended that you call both of the above preallocation routines for simplicity.
| -mat_type mpiaijcusparse | - sets the matrix type to "mpiaijcusparse" during a call to MatSetFromOptions() | |
| -mat_cusparse_storage_format csr | - sets the storage format of diagonal and off-diagonal matrices during a call to MatSetFromOptions(). Other options include ell (ellpack) or hyb (hybrid). | |
| -mat_cusparse_mult_diag_storage_format csr | - sets the storage format of diagonal matrix during a call to MatSetFromOptions(). Other options include ell (ellpack) or hyb (hybrid). | |
| -mat_cusparse_mult_offdiag_storage_format csr | - sets the storage format of off-diagonal matrix during a call to MatSetFromOptions(). Other options include ell (ellpack) or hyb (hybrid). |
