Microsoft Linux Cluster User Notes

Using the Linux Cluster

Get in touch

This is still a bit experimental, so mail Wes to get started.

Sort out your shares

• On linux, the ~ symbol refers to something that is probably not what you want - it's your local linux home directory, on the particular node that your job happens to get run on. So different jobs might have a different local linux home directory, because they might be run on different nodes.
• Instead, use ~/dide/home - which will be mapped to your DIDE home directory.
• If you want to have other shares mapped, then, edit or create a file in your DIDE home directory, called .pam_mount.conf.xml which contains something like this.

<?xml version="1.0" encoding="utf-8" ?>
<pam_mount>
  <volume options="vers=2.1,nodev,nosuid" user="*" mountpoint="/homes/<dide-username>/dide/tmp" path="Tmp" server="fi--didef2.dide.ic.ac.uk" fstype="cifs" />
  <volume options="vers=2.1,nodev,nosuid" user="*" mountpoint="/homes/<dide-username>/dide/f2gsim" path="GlobalSim" server="fi--didef2.dide.ic.ac.uk" fstype="cifs" />
  <volume options="vers=2.1,nodev,nosuid" user="*" mountpoint="/homes/<dide-username>/dide/nas1gsim" path="Test" server="fi--didenas1.dide.ic.ac.uk" fstype="cifs" />
</pam_mount>

• Obviously, replace <dide-username> with your username. So note here that /homes/<dide-username> is what Linux refers to when you use ~.
• The full path to your dide home directory, from a linux job, will therefore be: /homes/<dide-username>/dide/home.
