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
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.
