Limiting number of slots on cluster

The best solution I've come up with to limiting the number of slots assigned to long-running jobs on the cluster is denying access to nodes for the project involved. So, as of now, handalign is denied access on half the cluster nodes. Is there a better way to do this with share policies? It seems there's a better (or at least less confusing) option in SGE 6.1, 'Flexible Resource Quotas', but unfortunately we're running 6.0r3. Should think about upgrading at some point.

Random Notes

  • Burning ISOs from the command line on OS X, seems to be less cranky than disk utility: hdiutil burn youriso.iso
