EPSKrylovSchurSetPartitions
Sets the number of partitions for the case of doing spectrum slicing for a computational interval with the communicator split in several sub-communicators. 
Synopsis
#include "slepceps.h" 
PetscErrorCode EPSKrylovSchurSetPartitions(EPS eps,PetscInt npart)
Logically Collective on EPS
Input Parameters
|  | eps | - the eigenproblem solver context | 
|  | npart | - number of partitions | 
Options Database Key
|  | -eps_krylovschur_partitions <npart> | - Sets the number of partitions | 
Notes
By default, npart=1 so all processes in the communicator participate in
the processing of the whole interval. If npart>1 then the interval is
divided into npart subintervals, each of them being processed by a
subset of processes.
The interval is split proportionally unless the separation points are
specified with EPSKrylovSchurSetSubintervals().
