Notes: The arrays myapp and mypetsc must contain the all the integers 0 to napp-1 with no duplicates; that is there cannot be any "holes"
in the indices. Use <A HREF="../AO/AOCreateMapping.html#AOCreateMapping">AOCreateMapping</A>() or <A HREF="../AO/AOCreateMappingIS.html#AOCreateMappingIS">AOCreateMappingIS</A>() if you wish to have "holes" in the indices.
Comparing with <A HREF="../AO/AOCreateBasic.html#AOCreateBasic">AOCreateBasic</A>(), this routine trades memory with message communication.
