I'll take a look - offhand, I don't know of anything limiting you to

I have a problem starting large SMP jobs (e.g., 64 processes on a

(Guessing.) Does the following ring any bells?

It looks like MPI_INIT failed for some reason; your parallel process
is
likely to abort. There are many reasons that a parallel process can
fail during MPI_INIT; some of which are due to configuration or
environment
problems. This failure appears to be an internal failure; here's some
additional information (which may only be relevant to an Open MPI
developer):
orte_grpcomm_modex failed
--> Returned "Not found" (-13) instead of "Success" (0)

*** An error occurred in MPI_Init
*** before MPI was initialized
*** MPI_ERRORS_ARE_FATAL (your MPI job will now abort)
[burl-t5440-0:6756] Abort before MPI_INIT completed successfully;
not able to guarantee that all other processes were killed!
