What is Jupyterlab and how do I use it?

For more information about jupyterlab, please read the jupyterlab user guide: https://jupyterlab.readthedocs.io/en/stable/user/interface.html

How many resources should I request?

Please request only the resources that you need. For example, if you are just running very small calculations that do not require a lot of memory and cannot run in parallel, please request 1 core 4 GB memory. If you need slightly more horsepower than your laptop, 4 core x 16 GB memory or 4 core 32 GB memory should be fine. If you need more cores, 12 core options are available. 12 cores 128GB memory should be used only when absolutely needed. 

How can I relinquish my resource allocation?

Open

Then, click "Stop My Server"

How can I access my environment variables from the terminal?
