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.
