Is there an alternative for the -nolocal option when I execute mpiexec?

-nolocal is no longer required. mpiexec takes the list of hosts you want to run the application on. If you don’t give the local host in that list, it won’t run anything locally.

What's the difference between mpirun and mpiexec?

None. Both of them are symbolic links to mpiexec.hydra. — Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji
