Getting Started

To be eligible for access, please check with our Account Request section, subsection 'Eligibility' which is located within HPC Policies and Procedures.

  1. To access the HPC cluster, you must have an active UHD account. To obtain a UHD HPC cluster account, you must meet all the “Eligibility" requirements as stated above and then request an account here. This account allows you to log in to the login/head node of the cluster and communicate with the compute nodes.

  2. To access UHD's HPC cluster, you will need a secure SSH client. This is the only way to connect to the login/head node. Here are a few SSH client recommendations to access the login/head node.

  • SSH Secure Shell – SSH Secure Shell is a free implementation of SSH and Telnet for Windows. It also has an SFTP application for secured file transfers.
  • PuTTY SSH - PuTTY is a free implementation of SSH and Telnet for Windows and Unix platforms, along with an xterm terminal emulator.
  • XShell SSH - The XShell is a powerful terminal emulator that supports SSH1, SSH2, SFTP, TELNET, RLOGIN, and SERIAL. XShell is free for home and school usage.
  • Windows Command Prompt (cmd.exe) – To access the login/head node using the built-in Windows Command Prompt, on your keyboard click the Windows key + r. In the search box, type in cmd.exe and hit enter. When you see c:\users\username> type in “ssh <username>" and hit enter.
  • Once you have a UHD HPC account and your preferred SSH client installed, now is time to connect to the login/head node. You can connect to the login/head node on or off campus. Configure your SSH client to connect to the following addresses:

    • On Campus:
    • Off Campus:
  • IMPORTANT: Please change your password once you log in using the command $passwd

  • When you have logged in, you will see [<username>@login ~]$. This is where you can start typing out commands. To learn more about Linux commands and navigating through the Linux terminal, take a look at our Linux Basics page.
