High Performance Computing

  • Chinook

    Penguin Computing Community Cluster

    Chinook is the foundation for a new energy-efficient, condo-style HPC cluster for UA researchers. The computing environment hosted on Chinook includes:

    • 100+ Relion 1900 Compute Nodes each with dual Intel Xeon 12- or 14-core processors (24 or 28 cores per node) and 128 GB memory
    • 3x Relion 1900 Compute Nodes each with dual Intel Xeon 14-core processors (28 cores per node) and 1.5 TB memory
    • 2x Relion 1903GT Compute Nodes each with dual Intel Xeon 14-core processors (28 cores per node), 128 GB memory, and 2 dual GPU Tesla K80m accelerators
    • Multiple login nodes with dual Intel Xeon processors and 48 or more GBs memory
    • CentOS operating system, Slurm open-source workload management software, and Scyld ClusterWare HPC management software
    • Compute and login node access to the 307 TB Lustre scratch file system
    • Login node access to the 7+ PB long term tape storage file systems

    Are you interested in using the Chinook HPC cluster in your computational work? Please read our directions on how to obtain RCS project and user accounts.

    In 2016, the Geophysical Institute launched Chinook as an energy efficient linux cluster purchased from Penguin Computing, Inc. Chinook is named in honor of long time GI colleague Kevin Engle's unique, strong, collaborative nature and passion for salmon and Alaska. In 2016 and 2017, Chinook expansions were supported with funding from the M. J. Murdock Charitable Trust. Chinook is also made possible by the Geophysical Institute, IARC, the Institute of Arctic Biology, the Vice Chancellor of Research, and your fellow colleagues who contribute shares.

  • XSEDE/Campus Champions

    Members of RCS staff are part of XSEDE's Campus Champions program, providing support and contacts for XSEDE systems and XSEDE startup allocations. Please contact RCS if you are interested in pursuing XSEDE resources.


  • Digdug

    Lustre File System

    Dig Dug is a non-commodity cluster hosting 275 Terabytes of fast-access scratch storage for the RCS HPC clusters. UA researchers utilize this resource for program compilation, data manipulation and massive short-term file input/output storage. Dig Dug
    serves the Gemini and Infiniband interconnects and Ethernet connection to the HPC clusters.

  • Bigdipper

    Sun SPARC Enterprise T5440 Server

    Bigdipper hosts the long term mass file storage for RCS user data. Offering 214 Terabytes of local disk cache and management of the long term file writing and staging requests to tape, Bigdipper works in conjunction with the automated tape library to
    offer access to over 7 Petabytes of file storage.

  • Galaga

    IBM System Storage TS3500 Tape Library

    Galaga is home to over seven Petabytes of enterprise-scale, long-term data storage on the UAF campus. Hosting an automated tape cartridge system with an available tape slot count of over 2,600, this system presents a seemingly unlimited file storage
    solution to the UA community.
