Thank you Pavan, Just to clarify: you were able to run the program that accesses /dev/mem not just mpiexec id? I did not want to spend a whole day installing hydra instead of smpd if it would not work. Thank you everyone for your help!

Antonio set up a ticket http://trac.mpich.org/projects/mpich/ticket/1885 to check whether the problem would still occur in hydra. Could you please run the test provided there with hydra and see if it works?

I've verified that it works correctly and resolved the ticket. Please only use hydra. -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji
