#include "petscao.h" PetscErrorCode AOCreateMemoryScalableIS(IS isapp,IS ispetsc,AO *aoout)Collective on IS
|isapp||- index set that defines an ordering|
|ispetsc||- index set that defines another ordering (may be NULL to use the natural 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.
