Looks like the directory that your MPI executable 'test' is in is: /home/npsf/last Correct? This directory needs to be visible on each node used by MPI to run your program. You might also need to put a ./ in front of the name of the executable, as in ./test . You also need be able the 'rsh' to each of those nodes. Because you have not specified a 'machines' file, MPI is using the default file in the install tree which normally lists the nodes in simple sequence. Still, I think the problem option 1 or 2 above. rbw _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
