In today's compute-intensive research environment, it is important to have resources that are able to perform particular tasks. ARCC provides users with The Teton Compute Environment, which is a high-performance computing (HPC) cluster with over 500 compute nodes that allow researches to perform computation-intensive analysis on large datasets. Built-in tools and the ability to request custom tools allow users to fine-tune their research procedures and have control over their data, projects, and collaborators. **ADD SOMETHING ABOUT LOREN

Overview

As research becomes more compute-intensive, ARCC has made high performance compute a core service. This core service is currently being performed by The Teton Compute Environment, allowing researchers to perform computation-intensive analysis on large datasets. Using Teton, researchers have control over their data, projects, and collaborators. Built-in tools help users get up and running in a short amount of time, and the ability to request custom tools allows users to fine-tune their research procedures.

Condo Model

The model for sustaining the Condo program is premised on faculty and principal investigators using equipment purchase funds from their grants or other available funds to purchase compute nodes (individual servers) which are then added to the Teton compute cluster. Condo computing resources are used simultaneously by multiple users. Teton is a condo model resource and as such, investors do have priority on invested resources. This is implemented through preemption and jobs not associated with the investment could be requested on the system when investor submits jobs. However, if the investor chooses not to implement preemption on their resources, ARCC can disable preemption while offering next-in-line access if that mode is preferred.

...

• Finally, individual jobs occur runtime limits based on a study that was performed in ~2014 such that our maximum walltime for a compute job is 7 days. ARCC is currently evaluating this to determine whether the orthogonal limits of CPU count and walltime are optimal operational modes. ARCC is considering concurrent usage limits based on a relational combination of CPU count, Memory, and walltime that would allow more flexibility for different areas of science. There will likely still be an upper limit on individual compute job walltime as ARCC will not allow infinite job walltime and due to possible hardware faults.

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.
