> Any chance you could upgrade to Open MPI 1.5.5? It has a better version of the processor affinity stuff than the 1.4 series.
Did this and recompiled everything that depended on OMPI. No difference whatsoever. It still tells me, if I specify -np 2 for example, that "There are not enough slots available in the system to satisfy the 2 slots that were requested by the application." >My bad. I did not read the bottom part of the email. Not sure If this would help, but can u try, --mca btl sm,self ? This also does not change anything... Really confused what is going on here! Kyle
