    SALT LAKE CITY and BERKELEY, Calif., Aug. 16 /PRNewswire/ -- Linux Networx
 and the U.S. Department of Energy's (DOE) Office of Science announced today
 that DOE's National Energy Research Scientific Computing Center (NERSC) at
 Lawrence Berkeley National Laboratory has accepted a 722-processor Linux
 Networx Evolocity(R) cluster system for full production use by researchers
 across the nation.
     Named "Jacquard," the Linux Networx system will provide computational
 resources to scientists from DOE national laboratories, universities and other
 research institutions to support a wide range of scientific disciplines
 including climate modeling, fusion energy, nanotechnology, combustion,
 astrophysics and life sciences.  Established in 1974, NERSC is DOE's flagship
 facility for unclassified supercomputing.
     The acceptance test included a 14-day availability test during which a
 select group of NERSC users were given full access to the Jacquard cluster to
 thoroughly test the entire system in production operation.  Jacquard had a 99
 percent availability uptime during the testing while users and scientists ran
 a variety of codes and jobs on the system.  The thorough acceptance testing by
 NERSC ensures Jacquard is ready for a production environment for thousands of
 scientists and researchers across the nation.
     "NERSC is the leading provider of computing resources for DOE's Office of
 Science and this new system will provide valuable computational science
 support for a wide range of users, allowing them to run more detailed
 simulations with faster turnaround, thereby helping advance scientific
 discovery," said NERSC General Manager Bill Kramer.
     The Jacquard system is one of the largest production InfiniBand-based
 Linux cluster systems and has met rigorous acceptance criteria for
 performance, reliability and functionality.  Jacquard also takes advantage of
 Mellanox 12X InfiniBand uplinks in its fat-tree interconnect, reducing network
 hot spots and improving reliability by dramatically reducing the number of
 cables required.
     The system has 722 dual AMD Opteron(TM) processors, Model 248, with 640
 processors devoted to computation, and the rest used for I/O, interactive
 work, testing and interconnect management. Jacquard has a peak performance of
 3.1 trillion floating point operations per second (teraflop/s). Storage from
 DataDirect Networks provides 30 terabytes of globally available formatted
     "By delivering this system to NERSC, we've provided a highly productive
 computing system to over 2,500 users nationwide," said Robert (Bo) H. Ewald,
 CEO of Linux Networx. "We are committed to providing NERSC with the most
 advanced high-performance computing system available and are thrilled that
 this system will be a key part of major research initiatives taking place
 throughout the country."
     Following the tradition at NERSC, the system was named for someone who has
 had an impact on science and/or computing. In 1801, Joseph-Marie Jacquard
 invented the Jacquard loom, which was the first programmable machine. The
 Jacquard loom used punched cards and a control unit that allowed a skilled
 user to program detailed patterns on the loom.
