||If you have not yet acquired an account with the HPC, please email the HPC Administratorswith your full name.
To receive an account, you must be an enrolled student, faculty, or conducting research
affiliated with a department within the University of Memphis. If the latter case
applies, then we must have verification from the department which will sponsor your
time on our resources and we may discuss this on a case by case basis.
Once you have acquired a [username] you may open up a s(ecure)sh(ell) to 1 of 4 login nodes (login0-3) by opening up a Terminal window (Unix/Linux/Mac)
and submitting the following command:
||Windows users will most likely need to install an application such as PuTTY, a SSH client which offers a graphical user interface where you can input the necessary
login information, such as your username, password, and the the host name for our
login node penguin.memphis.edu (or just penguin). An SFTP(Secure File Transfer Protocol) client such as WinSCP or Tunnelier will also be necessary for uploading to, and/or downloading from, your share on the
cluster. Please read the paragraph directly below for information on how to connect
to the cluster from off campus, keep in mind that if you are able to secure an off
campus connection you will need to appropriately configure whichever third party application(s)
you decide to use.
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.
If you are logging into the cluster for the first time, you will need to immediately
change the temporary password initially given to you. This process should begin automatically
when you login for the first time. If not, or if you would like to change your password
at any other point in time, you can use the command:
If you cannot remember your password, please email the HPC Administrators and it will be reset for you.
