General Workflow of Running a Calculation
On a compute cluster, you do not simply run log in and your software, but you write a "job script" that contains all commands to run and process your job and send this into a waiting queue to be run on one of several hundred computers.

Learn about Scaling your Job
How many compute-cores should my job use? This depends on the software and the problem you are trying to solve. But if you use too few cores, your computation may take much too long - if you use too many cores, they will not improve the speed of your computation and all you do by using more cores is wasting compute resources and energy.
If you run hundreds or thousands of similar calculations, you should look at this carefully before starting.
How to do this is described in: Scaling
