    Hi,

    Im glad I found this group. I have a tiny homemade cluster. Some of the machines are Dual core and some single core. How would I specify number of processes as well as number of cores (for hosts that have more than one core) in the same mpiexec command line?

    Thanks.

    Hello Saurabh,

    You can run your mpi app with the following command line, suppose machine 1 is dual core and machine 2 is single core:

    mpiexec -hosts 2 [machine 1 hostname or IP address] 2 [machine 2 hostname or IP address] 1 [your mpi app]

    Thanks,

    James
