The Teton Compute Environment, or Teton for short, is a high performance computing (HPC) cluster with over 500 compute nodes that allow researchers to perform computation-intensive analysis on large datasets. Teton contains high performance data storage systems that have 1.2 PB of storage to accommodate some of the largest datasets. The Teton Compute Environment gives researchers the ability to have control over their data, projects, and collaborators. Teton can be securely accessed anywhere, anytime with 98% expected uptime and SSH connectivity using UWyo two-factor authentication.




Teton was preceded by UWyo’s first community HPC cluster, Mount Moran, which went into service in 2012. The second generation of HPC at UWyo, Teton, first went into service in 2018 and is available to all research interests at UWyo. With over 1.2 PB of storage, Teton can accommodate some of the largest datasets. Isolated filesystems ensure that researchers have control of where their data are, and who can access it. 

Teton Filesystems

The Teton global filesystem has three main filesystems called homeproject, and gscratch. The home area is for configuration files and software installations for each user, the project area is for collaboration among project members, and the gscratch area is for personal compute on larger datasets and is not backed up. Users with datasets on gscratch should remember to migrate them somewhere else once their computation is complete or risk losing all their data. 

Project and Account Requests

For research projects, UWyo faculty members (Principal Investigators) can request a Project be created on Teton. PIs can then add access to the project for UWyo students, faculty, and external collaborators. User Accounts on Teton require a valid UWyo e-mail address and a UWyo-Affiliated PI sponsor. UWyo faculty members can sponsor their own accounts, while students, post-doctoral researchers, or research associates must use their PI as their sponsor. Non-UWyo external collaborators must be sponsored by a current UWyo faculty member.

View the Account Policy page for additional information and policy statements on account usage. Use the link under "Account Requests" to request that either a project or user(s) be created or added. From this same page, you can request that users be added to an existing project.

Note, that for external collaborators a special UWYO account must be created by the ASO office before access can be granted to Teton. There is a one time $10 fee for having these accounts created. Please allow extra time for the ASO office to create the account.

Please go to this web page to request a project be set up, ARCC Access Request Form.

Once the form is submitted, and the information verified, the project and user account(s) will be created. Users will receive an email notification once a project has been created and/or when they are added to a project.

To request access for instructional use, send an email to arcc-info@uwyo.edu with the course number, section, and student list. If the PI prefers generic accounts can be created instead of providing a student list. Instructional accounts are usually valid for a single semester and access to the project is terminated at the beginning of the next semester.

Specialty Clusters

For those with very specific computing needs, ARCC is here to support you with the option of specialty clusters. If this is something you are interested in or would like to learn more, please contact ARCC or schedule an appointment to meet with ARCC staff.
