Logging in to the cluster

To log into the cluster, you need to use a an SSH client and connect to hpc.usd.edu.

Unless you have arranged otherwise, your username and password are your regular USD username and password.

Note: Usernames are case sensitive — if your username is Jon.Smith, logging in a jon.smith will not work.

Windows

  1. Install PuTTY
  2. Launch PuTTY
  3. Type hpc.usd.edu in the Host Name field, and click Open.
  4. If this is your first time connecting to the cluster, you may see a Security Alert window. Click the Yes button on this window.

Mac & Linux

  1. Use the ssh command from the Terminal application on Mac OS X or Linux (ssh yourusername@hpc.usd.edu).
  2. If this is your first time connecting to the cluster, you may see a message asking if you are sure you want to connect. Type yes.

Configuring X11 Forwarding

Some applications (like MATLAB and GaussView) have graphical interfaces that require an X display. To run these applications, you need to have a program called an X server running on your computer (Mac and Linux have this by default) and enable X11 Forwarding in your SSH client.

Windows

Install an X server, such as Xming. This only needs to be done once. Then:

  1. Ensure your X server is running.
  2. Launch PuTTY
  3. Type hpc.usd.edu in the Host Name field Navigate to Connection->SSH->X11
  4. Select Enable X11 forwarding as shown below

  5. Click Open, providing your username nad password when prompted

Mac and Linux

Pass the -X option to the ssh command, for example

ssh -X yourusername@hpc.usd.edu
