#include "petscksp.h" PetscErrorCode PCRedundantSetNumber(PC pc,PetscInt nredundant)Logically Collective on PC
| pc | - the preconditioner context | |
| nredundant | - number of redundant preconditioner contexts; for example if you are using 64 MPI processes and use an nredundant of 4 there will be 4 parallel solves each on 16 = 64/4 processes. |
