AOCreateMemoryScalableIS

 Creates a memory scalable application ordering using two index sets.

Synopsis

#include "petscao.h"   
PetscErrorCode  AOCreateMemoryScalableIS(IS isapp,IS ispetsc,AO *aoout)
Collective on IS

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.
