33-XServe Cluster Achieves 217 GigaFlops
XServe Cluster achieves over 1/5 TeraFlop using 66 1-GHz G4's
Huntington Beach, California, USA - November 14, 2002 - Dauger Research, Inc., announces
today that a 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, achieved over 217 billion floating-point operations per
second on a cluster of 33 XServes.
The Applied Cluster Computing Group (formerly known as
the High-Performance Computing Group) at
NASA's Jet Propulsion Laboratory (JPL)
recently acquired 33 XServes for the purpose of using them as a parallel
computing cluster. Using
Pooch, provided by Dauger Research, the JPL
group has begun running parallel computing code on their
new XServe cluster.
widely publicized as Apple Computer's entry into server
and large-scale scientific computing markets, has finally been
used successfully for a large numerically-intensive calculation.
Among the codes executed on the cluster,
the AltiVec Fractal Carbon demo was
one that achieved over 1/5 of a TeraFlop
(1 TF = 1000 GF = one trillion floating-point operations per second).
This result is the largest calculation yet performed on an XServe cluster.
The software used to obtain this impressive result is
the latest incarnation of
AppleSeed, a project begun
by physics researchers at UCLA in 1998. For four years and counting,
their software is being used world-wide to transform Macintoshes into easy-to-use,
numerically-intensive parallel computers. Complementing
a benchmark performed
using 76 Power Macintoshes at the University of Southern California (USC) in December 2001,
this most recent calculation demonstrates the potential scalability and computational
power of clusters based on the XServe.
The hardware included 33 Dual-Processor G4/1GHz XServes and
one 48-port 100BaseT 3COM switch.
The application code was
the AltiVec Fractal Carbon demo,
MacMPI_X.c for its message passing.
The operating system was
Mac OS X Server 10.2, and
the parallel computing code was launched and managed using

A representative of Dauger Research, Inc., will be available at
next week's SuperComputing 2002 conference
to discuss this result.
