PEPCISSSetRefinement#

Sets the values of various refinement parameters in the CISS solver.

Synopsis#

#include "slepcpep.h" 
PetscErrorCode PEPCISSSetRefinement(PEP pep,PetscInt inner,PetscInt blsize)

Logically Collective

Input Parameters#

  • pep - the polynomial eigensolver context

  • inner - number of iterative refinement iterations (inner loop)

  • blsize - number of iterative refinement iterations (blocksize loop)

Options Database Keys#

  • -pep_ciss_refine_inner - Sets number of inner iterations

  • -pep_ciss_refine_blocksize - Sets number of blocksize iterations

Note#

PETSC_CURRENT can be used to preserve the current value of any of the arguments, and PETSC_DETERMINE to set them to a default value.
