Notes

If you are a member of a group with a commitment, then these costs get deducted from that commitment. Typically we are fairly lax with enforcing limits - only once you get to around 150% of your commitment will we consider taking action (mainly coming to discuss things).

Example

You are running a job that needs 4 cores, 32G of RAM and runs for 90 minutes in the Std partition. To run this, you over-request resources slightly, and execute in a job that requests 4 CPUs, 40G of RAM and with a time limit of 3 hours. Your job terminates early. Thus, your costs are:

4 * 0.015 * 1.5 = 0.09 EUR for the CPU

40 * 0.0015 * 1.5 = 0.09 EUR for the memory

Total: 0.18 EUR
