AOCreateMemoryScalableIS#
Creates a memory scalable application ordering using two index sets.
Synopsis#
#include "petscao.h"
PetscErrorCode AOCreateMemoryScalableIS(IS isapp, IS ispetsc, AO *aoout)
Collective
Input Parameters#
isapp - index set that defines an ordering
ispetsc - index set that defines another ordering (may be NULL to use the natural ordering)
Output Parameter#
aoout - the new application ordering
Notes#
The index sets isapp and ispetsc must contain the all the integers 0 to napp-1 (where napp is the length of the index sets) with no duplicates; that is there cannot be any “holes”.
Comparing with AOCreateBasicIS(), this routine trades memory with message communication.
