    PARL Attends Supercomputing 2002 in Baltimore, MD
         Wed Nov 27 11:11:55 EST 2002
    Walt, Dan, Nathan, Phil, Will, Dale, and Tim from the PARL attended Supercomputing 2002 in Baltimore, Maryland. We manned a portion of the NASA Goddard Space Flight Center booth. Demos of Coven and PVFS were given. Posters of our problem solving environment, reconfigurable computing, parallel file system, and metasceduler focus areas were on display.

    PARL 2002 Lab Retreat/Summit
         Thu Aug 22 11:43:33 EST 2002
    On Tuesday, August 20, the PARL group held its first anual PARL Retreat at the Madren Center. PARL is now made up of five faculty members and dozens of students. The retreat was a great opportunity to meet everyone and learn about the various lab projects. We also identified several new areas of collaboration. Presentations were given by Dr. Stanzione, Dr. Ligon, Dr. Sass, Dr. Hoover, Nathan DeBardeleben, and Phil Carns on topics ranging from lab history to specific project summaries. This page gives a summary of the event.

    Coven Paper and Presentation From HPDC 2002 Online

    The Coven paper entitled "Coven - a Framework for High Performance Problem Solving Environments" published in and presented at The Eleventh IEEE International Symposium on High Performance Distributed Computing (HPDC-11) is available on the PARL techreports page. The presentation is available there as well. The conference was held in Edinburgh, Scotland. Walt Ligon and Nathan DeBardeleben attended the conference and Nathan presented the paper.

    CERSe Paper and Presentation From SDPW 2002 Online

    The CERSe paper and presentation from the Science Data Processing Workshop 2002 are available on the PARL techreports page.

    Cluster Web Pages
         Mon Mar 4 09:52:47 EST 2002
    Our clusters are all listed on the right hand side. Most now have web sites. The majority of the clusters are developmental machines and testbeds but our Mini-Grid consists of 528 processors spread between four clusters. Aetherwulf was delivered to Code 935 at NASA's Goddard Space Flight Center on February 27th. A web page documenting the construction is here. Travelwulf now has a web page as well, here. Webwulf's web page has been brought back online as well here.

    Here is a photo of some of the PARL team at Supercomputing 2001. From left to right we see Dr. Dan Stanzione, Carel Lewis, Dr. Walt Ligon, and Keith Underwood. This is what our booth looked like at the conference. Notice the posters of problem solving environments, beowulf system software, and PVFS as well as live demos on those two obscured podiums.

    PARL Appears at Supercomputing 2001
         November 10 - 16, 2001
    Many PARL students and faculty demonstrated high performance computing code at Supercomputing 2001 in early November at the Denver Convention Center. PARL appeared as part of the NASA Goddard Space Flight Center booth. PVFS, Coven, and CERSe were demonstrated live on travelwulf. Posters described this work as well as Balloc and the Clemson Mini-Grid. A paper on reconfigurable computing was presented as part of the conference by Keith Underwood. A paper as well as part of a tutorial was presented by a former PARL Ph.D. student, Dr. Robert Ross.
