How to make cluster accessible for multipe users

Hi,

What's the best way to manage users in a supercomputer?

I have the following setup:

- a headnode: users login to the headnode and are able to submit there jobs from there.

- multiple compute nodes: receive the job request and use their hardware to complete it.

There's a software share on the headnode which is accessible from all the nodes.

The thing is if i want to add a new user i have to manually add the user on each node. How is this done in most clusters?

Hi,

traditionally this sort of thing would have been done with nis, but more recently I think some people are using ldap.

EDIt: And of course here I'm assuming you have shared /home and /data (or whatever) partitions over nfs.
