#include "petscksp.h" PetscErrorCode KSPPIPEGCRSetMmax(KSP ksp,PetscInt mmax)Note: mmax + 1 directions are stored (mmax previous ones along with a current one) and whether all are used in each iteration also depends on the truncation strategy (see KSPPIPEGCRSetTruncationType)
Logically Collective on KSP
