High Performance Computing

The University of Kentucky has been a leader in High Performance Computing (HPC) for scientific research and teaching since 1987, and its supercomputers have ranked as high as #66 on the world-wide Top 500 list supercomputers list. These facilities are available to the faculty at UK and to research institutions throughout the state. Active research areas include physics, astronomy, biochemistry, pharmacy, medicine, mechanical engineering, and many others. The University also participates in networks of research supercomputers and collaborates with researchers across the country and around the world.

Computing Resources

Computing resources available to the University of Kentucky research community.

  • The Lipscomb High Performance Computing Cluster (dlx.uky.edu)

    The Lipscomb cluster is the backbone of the facility and is located in McVey Hall. It was named after UK alumnus and Nobel Laureate Dr. William N. Lipscomb, Jr. The cluster is built from a large number of commodity servers, a high speed interconnect, a unified file system, and a large mass storage system. For details on the cluster hardware, please refer to the Hardware page. If you're new to the cluster, then read the Getting Started pages. Everyone using the cluster should look at the README FIRST page.

    Scheduled Downtime:The Lipscomb cluster has quarterly outages scheduled for system maintenance, normally on the second Monday of January, April, July, and October, from 8AM until 4 PM. Schedule long running jobs accordingly. When no maintenance is required, outages will be canceled. See the System Status when logged onto DLX (enter the sysstatus command) or see the HPC News Blog for details.

  • The XGRID Cluster

    The Xgrid software from Apple, Inc. allows the use of idle Macintosh computers for distributed computing. At the University of Kentucky 322 machines currently participate in the Xgrid. These 322 machines have 1,417 processors which, if all are available, give a computing capacity of 3.74 TF. For more information, see the Xgrid web page.

  • XSEDE — Extreme Science and Engineering Discovery Environment

    XSEDE is a single virtual system, supported by the National Science Foundation, that scientists can use to interactively share computing resources, data and expertise. For more information, see the UK XSEDE page or go to the National XSEDE web site.

The Center for Computational Sciences

The Center for Computational Sciences (CCS) is a major center for computational activity at UK and was started in 1987 as a center of Excellence in the Commonwealth of Kentucky. In the decades since, there has been a revolution in the penetration of computation into every level of academic, industrial and governmental life. The Center has been at the forefront of this revolution, now labeled as Cyberinfrastructure.

One of the many areas that CCS contributes to HPC on campus are consulting services for anything relating to HPC, i.e., porting of codes, installation of software packages, research computing, Digital Humanities, Data management plans, access to national HPC resources etc. Contact Michael Sheetz at CCS (859-257-8737) for a consultation.

UK HPC Email List

This is a low volume Listserv list for us to send information, notices, questions, and warnings to the whole UK HPC user community. We encourage everyone interested in High Performance Computing at the University of Kentucky to subscribe. Subscribe by sending email to LISTSERV@LSV.UKY.EDU with the single line SUB HPC in it. To leave the list, send the single line UNSUB HPC.


If you publish research based on your work on the Lipscomb HPC Cluster, we would appreciate being mentioned in the acknowledgment section. Here is an example:

We would like to thank the University of Kentucky Information Technology department and Center for Computational Sciences for computing time on the Lipscomb High Performance Computing Cluster and for access to other supercomputing resources.

Thank you for your support.
