[slurm-users] $TMPDIR does not honor "TmpFS"

[Douglas Duckworth]

Hi

We are setting TmpFS=/scratchLocal in /etc/slurm/slurm.conf on nodes and controller.  However $TMPDIR value seems to be /tmp not /scratchLocal.  As a result users are writing to /tmp which we do not want.

We are not setting $TMPDIR anywhere else such as /etc/profile.d nor do users have it defined in their ~/.bashrc or ~/.bash_profile.

We do not see any error messages anywhere which could indicate why the default value of /tmp overrides our value of of TmpFS.

As I understand prolog scripts can change this value though, if that's the case, then what's the purpose of setting TmpFS in /etc/slurm/slurm.conf?
