NERSC launches Linux Networx supercomputer into production.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 The National Energy Research Scientific Computing Center, or NERSC for short, is a designated user facility operated by Lawrence Berkeley National Laboratory and the Department of Energy. (NERSC NERSC National Energy Research Scientific Computing Center (new name)
NERSC Nansen Environmental and Remote Sensing Center (Bergen, Norway)
NERSC National Energy Research Supercomputer Center ) at Lawrence Berkeley National Laboratory Lawrence Berkeley National Laboratory and Lawrence Livermore National Laboratory, scientific research centers run by the Univ. of California, located in Berkeley, Calif., and Livermore, Calif., respectively. 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 hot spots

The system has 722 dual AMD (Advanced Micro Devices, Inc., Sunnyvale, CA, www.amd.com) A major manufacturer of semiconductor devices including x86-compatible CPUs, embedded processors, flash memories, programmable logic devices and networking chips. Opteron(TM) processors, Model 248, with 640 processors devoted to computation, and the rest used for I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output.

"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 (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. 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 Jacquard loom
Loom incorporating a special device to control individual warp yarns. It enabled production of fabrics with intricate woven patterns such as tapestry, brocade, and damask, and has also been adapted to the production of patterned knitted fabrics. , 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.
