The node you log into is determined by a "round-robin" scheme which will distribute users evenly among our login nodes. Also, please note, access to the cluster is restricted to connections within the University of Memphis's LAN (assuming that you are trying to ssh within the LAN, you can drop the ".memphis.edu" tag and merely use $ssh [username]@penguin ).

If you wish to access the HPC from outside the University's LAN you must secure an account on a host within the LAN that does allow for an off campus connection and log into their server before logging into the HPC cluster. It is the users responsibility to secure an account on a host server outside the HPC. One method for students and faculty is the University's Virtual Private Network (VPN), which only requires your UUID and password. Detailed information regarding installation and usage, as well as a comprehensive FAQs, can be found at the University's VPN site.
