Try to avoid NFS at all costs. (disclaimer, i'm pretty much just retyping what i've seen yesterday on the beowulf mailing list) NFS works well in a workstation environment where a user does some IO but is generally idle a lot of the day. NFS in a beowulf is not so good a choice because it's slow (especially without the 2.4 NFS backport) and has cache consistency problems. Bootup will suck, since 15 nodes are going to try to access the NFS server at once. (not that it can't handle it, but serving 15 root partitions takes time: time you could use doing computations) a lot of people do have an NFS home directory across the cluster, but the users (if they are looking to maximize their cycle usage) work from a /scratch or some other local filespace. ==rob -- Rob Latham: linux A-Team Bethlehem, PA USA GPG Fingerprint: EAE8 DE90 85BB 526F 3181 1FCF 51C4 B6CB 08CC 0897
