-In you working (home) directory create your project files for computing.  For example if using python create a python file "runSomeCode.py" with a editor.  Using VScode might be the easiest way for beginner to work on the cluster, setup. If using the command line you can use the editors vi(or vim) or nano.

 The cluster uses Slurm as a scheduler and workload manager.
 To submit your you need to create a file(batch file for Slurm), an example filed is already in your home directory called "myJob.sh", which can be used with minor adjustments.
-But user can also create their own batch file for Slurm, but the content of it must follow slurms ruleset to work and it must be executable.
