This matrix type is identical to MATSEQAIJCUSP when constructed with a single process communicator, and MATMPIAIJCUSP 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 mpiaijcusp | - sets the matrix type to "mpiaijcusp" during a call to MatSetFromOptions() | |
| -mat_cusp_storage_format csr | - sets the storage format of diagonal and off-diagonal matrices during a call to MatSetFromOptions(). Other storage formats include dia (diagonal) or ell (ellpack). | |
| -mat_cusp_mult_diag_storage_format csr | - sets the storage format of diagonal matrix during a call to MatSetFromOptions(). Other storage formats include dia (diagonal) or ell (ellpack). | |
| -mat_cusp_mult_offdiag_storage_format csr | - sets the storage format of off-diagonal matrix during a call to MatSetFromOptions(). Other storage formats include dia (diagonal) or ell (ellpack). |
