The Arctic Region Supercomputing Center (ARSC) is 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) offers high-performance computing (HPC) and mass storage to the UAF and State of Alaska research communities. Funding for ARSC operations is 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 focuses on the Earth's arctic region. Common projects include 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.


Since its founding in 1993, ARSC has hosted a variety of HPC systems. The following is a listing of various HPC systems acquired by ARSC over the course of time:

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

Current ARSC hardware and projects[edit]

Academic resources[edit]

  • Bigdipper — A Sun SPARC Enterprise T5440 Server connected to a Sun StorageTek SL8500 robotic tape library. Potential long term storage potential capacity is seven petabytes.[4]

Research systems[edit]

  • Quasar - IBM QS222 System [5]
  • Various additional research systems, including general-purpose GPU computing systems

HPCMP Enhanced User Environment[edit]

ARSC is under contract to operate the High Performance Computing Modernization Program Enhanced User Environment Test Lab for the Department of Defense. This consists of a small number of test systems with no operational data at the Lab. Also, ARSC is hosting a Cray XE6 named Tana with 256 CPUs and 2.36 TFLOPS. This is a test and development system for the HPCMP Open Research System's Cray, Chugach.
