Thanks for this Lachlan and thanks for the reminder.... Sorry, should also have mentioned, we use NFS for /usr/local, for /home and for our shared data area /group. Our scratch is local and in most cases, jobs copy their datasets across before starting. The time cost of that operation is really just a rounding error in the job runtimes in most cases.
Cluster uses Torque/Moab for queue/resource management and scheduling.
