Advanced Research Computing Center (ARCC)

A division of The Office of Research and Economic Development

Research and High Performance Computing at UW

High performance computing (HPC) plays an increasingly critical role in all areas of research. Complex phenomena can be examined, and systems optimized in a virtual research lab through modeling and simulation. Visualization and data-mining tools enable the understanding of various types of data sets. UW researchers, students and their collaborators have access to world-class computational resources, including the NCAR-Wyoming Supercomputing Center (NWSC), UW's Advanced Research Computing Center (ARCC), and the School of Energy Resources Visualization Center. The Information Technology Research Support Team’s purpose is to support and lead the University of Wyoming faculty, staff and students in using advanced computing to enhance their science and/or engineering research.

The ARCC's primary mission is to facilitate the research of UW faculty, researchers, staff and students by integrating compute resources (software and hardware), networking, data storage, information management, and human resources in an approachable and adaptable manner.

ARCC Announcements

ARCC User Drop-in Sessions happen every Wednesday morning from 10 AM to 12 PM in the ARCC Project room (IT building, room 325) excluding holidays or special events when ARCC staff are unavailable. These sessions are intended for individuals and small research groups to stop by to discuss their computing needs, troubleshoot any issues, and provide some one-on-one training. Topics can range from accessing and using ARCC resources, such as the Teton supercomputer and the petaLibrary storage system, to general help with any other questions regarding computing that you may have in your research. ARCC staff will be available during the scheduled time to do demonstrations and provide consultation. Feel free to bring along your own laptop if you wish, but it is not required.

All Mount Moran nodes have been reprovisioned within the Teton HPC Cluster. The login nodes and Globus nodes for Mount Moran will be available to access Bighorn storage until the end of 2018. Bighorn 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.

Performance of the BigHorn storage service continues to be unstable. We will be using maintenance days to investigate/optimize the file system. The more small files you can tar up together and/or data you can delete, the faster the work will be done. Currently there are over 200 Million files in BigHorn. All reductions are welcomed. Please note, Bighorn will be decommissioned on Jan 1st, 2019!

Resources and Services

The major ARCC resources available across UW are: Teton (HPC cluster), the petaLibrary (research storage), Linux desktop support, and HPC consulting. Other services available by arrangement.

These resources are supported on a best effort basis by the ARCC staff with the following service availability targets:

• Teton - 99% uptime (not counting scheduled outages)
• PetaLibrary - 99.99% uptime
• Linux desktop support - best effort, business hours only
• HPC consulting - business hours only

Access to/help with these resources can requested here: ARCC Access Request Forms. For further information, see ARCC Resources.
