that should be all you need to do, correct. > After doing this I wrote a simple MPI > program, compiled it and tried running on all the 4 nodes and I > got an error message saying the executable is not available on the other > three nodes, so the execution failed.

You can copy the program out to all nodes, or you can put it on a common file system. It will be easiest if the executable has the same path on all nodes, and if you specify the path to the executable. Sometimes it's as simple as a missing './' in front of the executable. ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
