This wiki is intended to be a collaborative effort and as such allows anyone with a UWYO account to edit content. Please consider your actions. It is intended to share information and best practices related to research computing among researchers and students. See How to login and the User's Guide for more information.

Prerequisites for Using ARCC Resources

There are a few things you must have in place before you can use ARCC High Performance Computing or Research Data Storage core services. They are:

  1. Be a UWYO Faculty Member or be sponsored by one
  2. Have an active UWYO account
  3. Enrolled in Two-Factor Authentication
  4. Internet Access

UWyo Faculty Sponsorship

For UWYO faculty members can sponsor their own HPC projects or Storage Allocations, while students, post-doctoral researchers, or research staff must use a UWyo faculty member as their Principal Investigator, or PI, as their sponsor.

This is because there must be an on-campus contact to be responsible for these projects, and if we are doing a job as a university, students will graduate and post-docs will get jobs and won’t be able to serve as long-term contacts.

An Active UWYO account

ARCC resources are reserved for current UWyo Faculty, Students, and staff who do research for the University. Therefore an active UWyo account is required to be eligible to use our resources.

However, if a student graduates or if a UWyo faculty member is working with a collaborator at another institution, but both require access to ARCC resources, the Faculty Principal investigator can request an external collaborator account get created for those situations.

An External collaborator is issued by UWIT and costs $10 as a one-time setup fee. Once the account is created then the Faculty PI can request the Collaborator to be added to their Teton project or petaLibrary allocation. You can request an External Collaborator account here:

It’s important to know that ARCC does not manage UWyo accounts, we rely on UWIT to manage these. If your UWyo account is locked out or having issues, ARCC is unable to fix problems. If you encounter problems, please contact UWIT for help.

Enrolled in Two-Factor Authentication

Two-factor authentication, or 2FA, strengthens access security by requiring two methods to verify your identity. These methods can include something you know -- like a username and password, plus something you have -- like a smartphone app, a token, or a phone number to approve authentication requests.

At ARCC we are dedicated to providing security to researchers’ projects, but want to make it as convenient as possible for them to do their work. Therefore, we must ask them to provide two-factors when logging into ARCC resources, while staying accessible.

One of our frequently asked questions is “Do I need a smartphone to use two-factor?” No, there are three ways of using 2FA at UWyo.

  1. Use the Duo mobile app. It’s the easiest to use and makes sense to many users who use their smartphone or tablet on a daily basis. Enroll here:
  2. Purchase a YubiKey. This is a small USB device that you can press to generate your second factor. It costs $50 and can be purchased from UWIT here:
  3. The minimum thing required for two-factor is a phone number. You can enroll any landline with Duo to get your second factor as a phone call. The link to do that is the same as option 1.

Internet Access

About that accessibility, ARCC resources are generally available on the Internet. Meaning, if you have internet access and the three prior prerequisites you can theoretically use ARCC resources from anywhere in the world.

UW Research Computing Environment

  • ARCC maintains an HPC cluster for research computing, named Teton ( All UW researchers can have an account on the system and requests for accounts can be completed online. Faculty are encouraged to seek funding to add capacity to this system, but this is not a prerequisite for its use. The research office provides annual funding to add capacity and replace any outdated hardware.
  • The previous HPC cluster was named Mount Moran and was used with the storage system called Bighorn. The migration from Mount Moran to Teton is complete. Any research projects that still have data on Bighorn will need to migrate it off. The login nodes for Mount Moran — and Bighorn Globus endpoint — will be available to access Bighorn storage until the end of 2018. The storage can also be accessed from Teton login nodes, but as a read-only filesystem to encourage the movement of data from Bighorn to the new Teton storage.
  • ARCC also maintains a more general research storage system called the petaLibrary, and various tools for facilitating storage and transfer of data.

Proposal Development

Proposal Development If you wish to state how you intend to use ARCC resources in a grant proposal, we have provided a couple of documents that might be helpful in your proposal development.
