Good Practice

Here are few guidelines and suggestions that prevent users accidently hogging all the computing resources.

All jobs that are expected to take more than 10 mins of CPU should be run at nice +18.

Low Priority Jobs: If you want to run a job at even lower priority, i.e. you are in no hurry and don't mind if other people's jobs take priority over yours then run them at nice +19.
Multiple Jobs: When you have several long jobs to run do not spread them over all our machines. Please try to limit yourself to no more than 3 or 4 CPUs in ordinary circumstances. Note that europa, callisto and ganymede each have two CPUs. Multiple jobs on one CPU should be set to run sequentially rather than simulataneously. Together these self-imposed restrictions should give all users a fair share of the CPU.

Urgent Jobs: If you need a large chunk of CPU for a week or less to finish something urgently then follow this procedure. Send an email to all the theorists (potential CPU users) explaining that you need priority on particular machine for a certain length of time. If no one complains simply run your jobs there at high priority, ie at nice +17 rather than nice +18.
Beware that unattended emacs sessions have a habit of going crazy and grabbing all the CPU on a machine. An alias of the following form prevents it from using more than 30 mins of CPU before terminating.

Other Resources: Note that the multiple CPUs on the IT service's Marvin machine are not heavily used and also have a reasonable allocation of disk space to go along with them.
