   *Drop is:

+     *    With 6 nodes at 8 cores each, DROP is designed for non-interactive queue-based parallel supercomputing.
   *Drop is not:
      *    For anything that is interactive, uses less than 8 parallel cores per job, is not queue-able, or generally takes less than a few nights to run on your desktop, you had better use one of the stand-alone servers.
      *    Drop has only scratch storage. Move important data to a different server. Anything on /data/ can be deleted without notice.
      *    Kindly note that this cluster comes 'as is' with no support from IT, Joeri or Jason.
+     *    The login node 'drop' is also the file server. Do not run jobs there, in for- or background.
   *Come see Joeri for an account

+      *RAID6, 20GB/user quota, nothing ever auto-deleted
     */data (crossmounted over all nodes) = RAID0, unlimited space
       *RAID0, 5TB, no quotas
       *heaviest users will have older data auto-deleted by semi-random script, so better clear it out yourself
+  * Login/master/fileserver node is "drop", nodes are called c0 to c5
+  * Queueing implemented to balance loads. Only use queue, do not start processing on your own.
+  * Cluster runs [[http://www.centos.org/|CentOS5]] (a version of RHEL) under [[http://www.rocksclusters.org/roll-documentation/base/5.1/|Rocks 5.1]]
