You are running a job that needs 4 cores, 32G of RAM and runs for 90 minutes in the std quality. 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:
You are running a job that needs 4 cores, 32G of RAM and runs for 90 minutes in the std quality. To run this, you over-request resources slightly, and submit a job that requests 4 CPUs, 40G of RAM and with a time limit of 3 hours. Your job is done after two hours, using at maximum 3 CPUs and 32G of RAM.


Thus, your costs are:


4 * 0.015 * 1.5 = 0.09 EUR for the CPU
4 * 0.015 * 2 = 0.12 EUR for the CPU


40 * 0.0015 * 1.5 = 0.09 EUR for the memory
40 * 0.0015 * 2 = 0.12 EUR for the memory


Total: 0.18 EUR
Total: 0.24
 
So you are billed for the duration that you claimed the 4CPUs and 40G of RAM, not the 3 CPUs and 32G RAM you actually used.

If you are a member of a group with a commitment, then these costs get deducted from that commitment. Once you get to around 125% of your commitment we will take action to fix things.

Example

You are running a job that needs 4 cores, 32G of RAM and runs for 90 minutes in the std quality. To run this, you over-request resources slightly, and submit a job that requests 4 CPUs, 40G of RAM and with a time limit of 3 hours. Your job is done after two hours, using at maximum 3 CPUs and 32G of RAM.

Thus, your costs are:

4 * 0.015 * 2 = 0.12 EUR for the CPU

40 * 0.0015 * 2 = 0.12 EUR for the memory

Total: € 0.24

So you are billed for the duration that you claimed the 4CPUs and 40G of RAM, not the 3 CPUs and 32G RAM you actually used.
