California Digital & Lawrence Livermore Deploy Fastest Linux
23 Teraflop Peak System Is World's Second Fastest
FREMONT, CA-[May 13, 2004]--Linux cluster vendor
California Digital, Quadrics, and Intel today announced that they
had successfully deployed the most powerful Linux supercomputer
ever built, a 4,096 Itanium2 processor based Linux cluster code
named "Thunder" at Lawrence Livermore National Laboratory.
The Thunder cluster delivers 19.94 teraflops of sustained performance,
making it the most powerful computer in North America. Thunder
also boasts the largest Itanium 2 processor deployment, as well
as the largest implementation of Quadrics' low-latency QsNet^II
interconnect technology. These technologies allow Thunder to achieve
record cluster efficiency of 86.9%, an important metric in measuring
"We're proud to have successfully delivered such a ground-breaking
Linux cluster with world-record performance and efficiency,"
reported California Digital CEO B.J.Arun. "Thunder sets important
benchmarks for massively-parallel Linux computing."
Thunder uses 1,024 California Digital 6440 servers, each with
four Intel Itanium2 1.4GHz processors with 4MB of cache, 8GB of
RAM, and 73GB of local storage. "Working with California
Digital and Lawrence Livermore has been a great opportunity to
demonstrate the absolute performance and scalability that can
be achieved with Intel's Itanium2 processor" said Intel Enterprise
Platforms General Manager Richard Dracott.
Thunder's efficiency and scalability rest on the strength of its
sophisticated interconnect technology, Quadrics' QsNet^II offering.
QsNet^II (Elan4) provides the underlying high bandwidth and low
latency MPI communications required by today's demanding scalable
applications. With support for broadcast in hardware and scaleable
collective operations, QsNet^II scales clusters efficiently to
over 4,000 nodes.
Despite the technical sophistication of Thunder and the incorporation
of new technologies, California Digital deployed Thunder in five
months, speeding delivery of computing solutions to support Lawrence
Livermore's national security and science programs in fields such
as materials science, structural mechanics, electromagnetics,
atmospheric science, seismology, biology, and inertial confinement
"Thunder represents the next generation of Linux cluster
for scientific simulation," remarked Mark Seager, Livermore's
Assistant Department Head for Advanced Technology. "Our applications
are seeing a 50% to 400% speed up over our Xeon base clusters."
Thunder uses a number of innovative open-source software tools
developed by California Digital and Lawrence Livermore to manage
the cluster effectively, leveraging the industry-leading remote
management capability of Intel's Itanium2 system family. California
released a number of these tools under open source licenses as
part of its freeIPMI project for server management and configuration.
