Debugging

Are you using the cluster for the First time?

Please do not start immediately with a 16-node and 40-hour calculation. Start with a short 5-minute run on 1 core. Then try more cores on the same node, Then try going beyond one node and then increase the system size and make your calculation longer.

If your job is failing, create a small example for you

Create something that runs in 5 minutes where you know the result and the timing. Run the small example.

Shorter example is easier to debug and does not queue "forever"
