#include "slepceps.h" PetscErrorCode EPSCISSSetSizes(EPS eps,PetscInt ip,PetscInt bs,PetscInt ms,PetscInt npart,PetscInt bsmax,PetscBool realmats)Logically Collective
| eps | - the eigenproblem solver context | |
| ip | - number of integration points | |
| bs | - block size | |
| ms | - moment size | |
| npart | - number of partitions when splitting the communicator | |
| bsmax | - max block size | |
| realmats | - A and B are real |
| -eps_ciss_integration_points | - Sets the number of integration points | |
| -eps_ciss_blocksize | - Sets the block size | |
| -eps_ciss_moments | - Sets the moment size | |
| -eps_ciss_partitions | - Sets the number of partitions | |
| -eps_ciss_maxblocksize | - Sets the maximum block size | |
| -eps_ciss_realmats | - A and B are real |
The default number of partitions is 1. This means the internal KSP object is shared among all processes of the EPS communicator. Otherwise, the communicator is split into npart communicators, so that npart KSP solves proceed simultaneously.
