I'm having trouble running apps with multiple inputs using the xgrid backend to mpirun. I can't find any options to send files to the nodes as I would be able to do via simple xgrid commandline options. In addition, the output files don't show up. E.g. when I run LAMMPS locally, I get a dump file, but when I run it on the cluster, no dump file. Is there a return mechanism in the current xgrid interface?
This is unrelated to Open MPI. I've been looking at setting up an NFS to deal with the input problems and make installation of MPI apps easier, but Mac OS X 10.4 seems to have NFS disabled somehow. Is there another protocol I can setup on 20 nodes without using a GUI on each node?
