Computing Information

These pages have information on the computing services and resources provided by the UVA Computer Science Department.

Computing services and resources are accessed via a CS Dept computing account. Faculty and graduate students have accounts created for them, undergraduates majoring in CS or taking CS courses can request a CS account.

When you start at UVA, you get a userid (something like “abc1de”), which you use to access general UVA sites like Collab or NetBadge systems. When you get a CS Dept. account, you will have an identical userid (“abc1de”), but a different password than the one you use for general UVA systems. When the CS account is created for you, you are sent an email with a temporary password that needs to be changed upon first login. See Account Information below.


2023 Summer Updates

  • Both the portal load balanced cluster and the nx (Nomachine) cluster have been updated to Ubuntu Server Linux 22.04 (from the deprecated CentOS Linux v 7). This update retains the software available on portal and Nomachine clusters, so users should not experience any difference in the servers' operations.
  • We have added four servers to the portal cluster, increasing the number of servers to ten.
  • All research servers (those whose access is controlled by the job scheduler (SLURM), have also been upgraded to Ubuntu Server 22.04.
  • NOTE: if you source software in the /sw/centos branch of software in your .bashrc or other login file, this may cause an issue with your login. You should change that to /sw/ubuntu. Software modules are already updated, so doing a 'module load' of software will work seamlessly.
  • New single mode fiber has been run to all floors of Rice Hall, and new 10Gb optics installed in floor switch stacks. This fiber is capable of 25, 40, and 100Gb throughput.

CS Account Password Reset

Reset your Computer Science Department account password: Use the Password Reset Tool

(New account users cannot use the password reset tool until they change their temporary password. See Account Information below.)

Server Software

Most common Linux software is already available on our systems! There is no need to install it. See Software Modules for more information.

Papercut Printing

Due to changes in Microsoft server, many Windows 11 laptops and desktops will no longer be able to print via our print server. To address this, we have deployed a solution called “papercut” that will help ease things.

Simply go to: Papercut server

You should be able to install and select printers following the prompts!

Account Information

Faculty and graduate students have Computer Science (CS) accounts created for them, undergraduates in CS or Computer Engineering (CPE) or taking CS courses can request an account by sending an email to

When your account for the Computer Science network has been created, you will be emailed the account information. Welcome!

Your account is for logging into servers and desktops within the CS Dept. It is NOT for CS websites or general UVA systems like Collab or other general UVA systems. Even though your user id is the same as your NetBadge user id used for UVA systems, your CS account password is only for CS Dept. servers and desktop systems.

New accounts are assigned a temporary password, so the first time you log in you will be asked to set a new password. The ONLY way to change your temporary password is to open a “terminal” window on your laptop or desktop, and use ssh to, for example “ssh”. You will then be asked for a new password, which you should set to a password you typically use. You will then use this password to login to all CS network systems. See Linux SSH Access for more information. You cannot use the Password Reset tool link above to change your temporary password.

Note: if you want to use a Linux remote desktop, (see: Nomachine Remote Desktop Sessions) you should FIRST login to portal to change your temporary password. The Linux remote desktop system will not let you login with that temporary password.

If you forget your CS password you can reset it using the Password Reset Tool.

Upon separation from UVA CS, your account will be closed one month after that separation, and your home directory will be removed. No backup will be provided, so it is important for you to save any files you wish to take with you onto other storage.

Regular accounts vs. mysql accounts

Please view this video for important information about mysql accounts. One thing not mentioned in the video is that your regular account and your mysql account are two different accounts with two different initial passwords, keep that in mind!

Using the CS Dept computing environment

The CS Dept provides extensive computing resources. The entry point these resources is the portal cluster, a load balanced cluster of systems providing general purpose computing. From portal, other servers are available that have GPU accelerators, large memory sizes, and large core counts.
