IIRC, you don't need to have a centralized user account management system, and in fact even same account w/ different UIDs *should* work. Grid Engine looks up the account information when it starts a job, so really a sync UID is not absolutely needed, but it can be if you have a shared filesystem that has ACLs that uses UID. Instead of implementing a centralized user account system, which *really* is lots of work, I think the best to approach is to find out why it can't write to the local disk. You can submit a job that runs "id", and output it to the shared FS, and check if the job is really running as the job owner. And then you can login as tommy and run something interactively and see if writing to the local disk is OK or not, etc... basically standard Linux admin stuff - you got the idea. :-) Rayson > > Thanks a lot for your responses...
