[slurm-users] Slurm and shared file systems

[David Baker]

Hello,

We are currently helping a research group to set up their own Slurm cluster. They have asked a very interesting question about Slurm and file systems. That is, they are posing the question -- do you need a shared user file store on a Slurm cluster?

So, in the extreme case where this is no shared file store for users can slurm operate properly over a cluster? I have seen commands like sbcast to move a file from the submission node to a compute node, however that command can only transfer one file at a time. Furthermore what would happen to the standard output files? I'm going to guess that there must be a shared file system, however it would be good if someone could please confirm this.

Best regards,
David
