Finding a terminal on Lynx

There are three good options.

1. Using SSH from a terminal on your laptop

• You may need to connect to the Penn State VPN prior to this method working.

• ssh to Lynx cluster

ssh userid@feed.lynx.hpc.psu.edu

• Login.

• Note that you'll likely have to complete 2 factor authentication again.

• Run script to setup the class environment

source ~/hpc4astro/astro_528/scripts/env_setup

• Note that if you try to use lots of memory or CPU resources, your session may be killed.

• Pro tip: If you want more resources than you can submit an interactive slurm job.

2. A terminal within the portal

• Open portal.lynx.hpc.psu.edu in your browser's guest or incognito mode.

• Log in with your Penn State credentials (and authenticate if necessary).

• Select Clusters > Shell Access

• Note that you'll likely have to complete 2 factor authentication again.

• Run script to setup the class environment

source ~/hpc4astro/astro_528/scripts/env_setup

• Note that these terminals time out relatively quickly. And if you try to use lots of memory or CPU resources, your session may be killed.

3. A terminal within JupyterLab

• Open portal.lynx.hpc.psu.edu in your browser's guest or incognito mode.

• Log in with your Penn State credentials (and authenticate if necessary).

• Request a Jupyter Lab session via the Lynx portal (see starting Jupyter Lab & Pluto Servers)

• Click Click to Connect to Jupyter button. Click it.

• Go to the newly opened tab, you'll have a Jupyter Lab Server or a Pluto Server.

• If you don't see tiles for Python, Julia and Pluto Notebooks, then click File.NewLauncher.

• Find the Terminal tile or in the menu system, File.New.Terminal.
