128-Xserve G5 Cluster Achieves 1.21 TeraFlop
"Dawson" Cluster exceeds a TeraFlop using 256 2-GHz G5's
Huntington Beach, California, USA - January 11, 2005 - Dauger Research,
Inc., announces today that a new milestone for cluster computing and the
Macintosh platform has been accomplished. Software written by
researchers at Dauger Research and the University of California, Los
Angeles, (UCLA) achieved 1.21 trillion floating-point operations
per second on a cluster of 128 Dual-Processor Xserve G5s.
The Plasma Physics Group at UCLA acquired 128 Xserve G5s to create the
new "Dawson" high-performance parallel computing cluster to advance plasma physics
research. Among the codes executed on the Dawson cluster, the AltiVec
Fractal benchmark was one that achieved over a TeraFlop (1 TF = 1000 GF
= one trillion floating-point operations per second). This result is the
largest calculation yet performed using Pooch Pro.
With the advent of the Dawson cluster, the Xserve has finally been
successfully applied to large numerically-intensive physics
calculations. Using Pooch Pro, provided by Dauger Research, this new
Xserve cluster ran parallel computing jobs that achieved over a
TeraFlop. A similar result using Linpack was accomplished on the Dawson
cluster, placing it in the most recent Top 500 Supercomputer list.
Most recently, the Pooch family introduced new technologies to access
and run clusters behind firewalls and automatically access job output.
Adding support for the use of Myrinet hardware from
Myricom and the
LAM/MPI implementation, Pooch today supports five distinct
MPI implementations, making good on its "MPI-agnostic" support for
The software that made the 1.21 TeraFlop result obtainable is
MacMPI, the latest incarnation of AppleSeed, a project begun by
physics researchers at UCLA in 1998. For seven years and counting, their
software is being used world-wide to transform Macintoshes into
easy-to-use, numerically-intensive parallel computers. Complementing
milestone benchmarks performed
using 76 Power Macintoshes at the University of
Southern California (USC) in 2001 and
another using 33 Xserve
G4s at NASA's Jet Propulsion Laboratory (JPL) in 2002, this
most recent calculation demonstrates the scalability and computational
power of clusters based on the Xserve.
The hardware included 128 Dual-Processor G5/2GHz Xserves and a Cisco
6500 Gigabit switch. The application code was the
AltiVec Fractal Carbon benchmark.
The operating system was
Mac OS X Server 10.3, and the
parallel computing code was launched and managed using
Pooch Pro. For
