ARSC Transitions to RCS

The Arctic Region Supercomputing Center resources, services, and expertise have transitioned to the Research Computing Systems (RCS) Group at the UAF Geophysical Institute.  RCS’ mission is to provide advanced computing, storage, data sharing solutions and research IT support to the UA research community and State of Alaska.

RCS is making some exciting changes in the year ahead, including the incremental deployment of a new energy efficient community HPC cluster.  We look forward to engaging with you, our users, throughout the process and will notify you of any changes to service in advance.

The following is the official UAF announcement introducing this transition:

New Unit to Serve UA Research Computing Needs
November 9, 2015
The University of Alaska Fairbanks Geophysical Institute has launched a new unit, Research Computing Systems.

The new unit will provide advanced computing, storage, data-sharing solutions and research information technology support to the University of Alaska research community and state of Alaska.

Research Computing Systems will provide services similar to those offered by the former Arctic Region Supercomputing Center, which was dissolved earlier this year. ARSC users will not experience a disruption in services without adequate notice.

The website for RCS is

Alaska Wildfire Tracking Web App Available!

UAF Geophysical Institute's Research Associate Professor Martin Stuefer and Research Assistant Christine Waigl's web application hosted on ARSC resources at has gained wide spread attention as the number of wildfires increases across the state.  Read more about the web application in the Alaska Dispatch News:

Important Announcement Regarding the HRRR-AK Model

Dear Colleagues,

Apologies for the short notice, but the HRRR-AK model behind will be temporarily suspended on Friday, 10 April 2015 in order to transition from the current, energy-inefficient computing platform to a newer system.  With this transition - which is expected to be complete by early summer - the HRRR-AK will be upgraded to newer versions of WRF and HRRR-specific routines, and new features are planned for incorporation.

Additionally, older, archived data will be removed, some of which dates back to 2010.  This will likely take place in the next month.  At this point, all raw NetCDF wrfout outputs that date earlier than 6 months ago will be removed.  A sliding 6-month archive window will be maintained.  Each forecast generates close to 400 GBytes of these wrfout files.  By removing these old files we anticipate freeing capacity to store more useful products in the future.

During this hiatus, we encourage you to provide us with thoughts and ideas how a revived HRRR-AK may better serve the needs of a Weather-Ready Alaska, providing forecasts and warnings for the protection of life and property and enhancement of the economy.  Please think about things like frequency and duration of forecasts, types of forecast and verification products, etc.  Some found our high-resolution HYSPLIT-ready output products to be useful.  Are these kinds of things worth considering?  We have put some thought into an optional, floating 1km nest (analogous to the 1km NAM NEST for fire weather) - what about this?  Most importantly, are there potential features to an enhanced HRRR-AK that we might be able to support through outside collaborations?  

Please share your thoughts with Dr. Don Morton <>.

EPSCoR Award Funds Two ARSC Web Sites

Part of the NSF Research Infrastructure Improvement Cyberconnectivity Award, administered by Alaska EPSCoR, funded two new ARSC Web sites. One of these sites is Alaska Data Central, which is designed to serve as a central access point for data and metadata from across the University of Alaska system. The other is Scholarworks, an institutional repository holding UA library materials, theses and dissertations, meeting minutes, scientific posters, and archival footage and images.

Attention Researchers!

If your research involves the use of ARSC resources, remember to mention ARSC in your publications acknowledgments!  We recommend a statement similar to, "This work was supported in part by a grant of HPC resources from the Arctic Region Supercomputing Center and the University of Alaska Fairbanks".

Information about how to incorporate ARSC utilization into grant proposals is available in the ARSC knowledge base
