Creates an application mapping using two integer arrays.
comm - MPI communicator that is to share the
napp - size of integer arrays
myapp - integer array that defines an ordering
mypetsc - integer array that defines another ordering (may be NULL to indicate the identity ordering)
aoout - the new application mapping
Options Database Key#
The arrays myapp and mypetsc need NOT contain the all the integers 0 to napp-1, that is there CAN be “holes” in the indices.
AOCreateBasicIS() if they do not have holes for better performance.
