The Arctic Region Supercomputing Center (ARSC) was from 1993 to 2015 a research facility organized under the University of Alaska Fairbanks. Located on the University of Alaska Fairbanks (UAF) campus, the Arctic Region Supercomputing Center (ARSC) offered high-performance computing (HPC) and mass storage to the UAF and State of Alaska research communities. Funding for ARSC operations was primarily supplied by UAF, with augmentation through external grants and contracts from various sources such as the National Science Foundation[1] and Lockheed Martin[2] (through the Department of Defense High Performance Computing Modernization Program.)

In general, the research supported with ARSC resources focused on the Earth's arctic region. Common projects included arctic weather modeling, Alaskan summer smoke forecasting, arctic sea ice analysis and tracking, arctic ocean systems, volcanic ash plume prediction, and tsunami forecasting and modeling.


ARSC has hosted a variety of HPC systems. Following is list of various HPC systems acquired by ARSC:

  • 1993 - Cray Y-MP named Denali with 4 CPUs and 1.3 GFLOPS, StorageTek 1.1 TB Silo.

  • 2011 - Expanded Pacman to 3256 CPUs and 200 TB Filesystem.


ARSC was dissolved as of Nov. 9, 2015, and its systems are now operated by the Research Computing Systems unit at UAF's Geophysical Institute. RCS provides services similar to those that had been offered by ARSC.[3] The RCS unit provides advanced computing, storage, data-sharing solutions and research information technology support to the University of Alaska research community and the state of Alaska.
