The diskless clients can have their root directories NFS mounted from, say, /nfsmount/10.0.0.1 etc. Their programs will be located in, for example, /mpiprog, which corresponds to /nfsmount/10.0.0.1/mpiprog on the BOOTP server (assuming that you are using BOOTP). Look for the HOWTOs on BOOTP, NFS, and Beowulf. Good Luck. Josh =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= = Josh Guffin guffin@purdue.edu = = Purdue U.
