Hardware: 16 dual processor G4/450
Project: Simulation of Extreme Plasma Physics
Development Environment: Absoft Fortran
The Laser and Plasma Group, Center of Plasma Physics. The ep2 cluster is capable of delivering over 50 GFlops of peak power, and it is based on 16 Dual PowerPC G4/450, 32 processors, 12 Gigabytes of RAM, 0.5 Terabyte of hard disk space. This is the fastest Macintosh-based cluster in the world. They plan to use it for numerical simulation of plasmas, novel plasma particle acceleration schemes, and relativistic shocks in astrophysics.
Location: York University, Toronto, CanadaThis cluster was created by Roman Koniuk and Chris Stewart
at the Department of Physics and
Astronomy at York University in Toronto, Canada. They are using the
cluster to investigate an area of particle physics named Quantum Chromodynamics.
Total time from arrival of equipment and software to executing parallel
code: 3 leisurely days. This cluster was featured in an
article by Apple Canada.
Location: University of Wisconsin, Madison, Wisconsin
Hardware: 6 G3/450s
Project: Medical Imaging
Development Environment: ?
Dept. of Medical Physics, Center for the Mathematical
Sciences. Facilities include 6 Macintosh G3/450's, and are used for
intensive medical imaging and massive data analysis. Initial tests
show performance of 1.7 GFlops!

Hardware: 1 G3/400, 4 iMac/233s, 3 PowerBook G3/333s,
1 PowerPC 8500/120
Project: Astronomy
Development Environment: Absoft Fortran/Metrowerks C
Mario Armando Higuera at Observatorio
Astronomico Nacional of the Universidad Nacional de Colombia tells
us that they have built a cluster of four iMacs's and an 8500 and are implementing
algorithms for matrix manipulation, Jacobi methods, and Fourier transforms.
Several teachers and students are involved in the OAN Appleseed Cluster
project, and they hope to expand with G3's in the future. Once their implementations
are complete, they plan to address problems in celestial mechanics, astrophysics,
and cosmology. This appears to be the first parallel Macintosh cluster
in South America.
R. Hixon and A. T. Norris said "The elapsed time from
unpacking the machines to running an existing parallel computational aeroacoustics
code on all 15 nodes was 14 hours, of which 8 hours were spent making connecting
cables and configuring the switch. Using the documentation from UCLA,
each machine took approximately 10-15 minutes to configure once started.
From the first code run, the Macintosh cluster ran flawlessly.
Moriel NessAiver at the
University of Maryland School of Medicine is building a cluster of
seven G3's for faster processing of raw data from Magnetic Resonance Imaging
medical scans.
Bedros Afeyan says that our work involves solving the
kinetic equations that describe nonlinear optical processes in large scale
length plasmas. Our emphasis is on direct Vlasov solvers, Wigner/Schrodinger-Poisson
systems, adaptive wavelet methods and comparison wth PIC codes. We
collaborate with scientists in Nancy, France, UCLA, SNL, LLNL, LANL, and
NRL on these projects. Speedup and compression using wavelet techniques
is the first and foremost goal towards which we direct our research efforts.
Dr.
Jay Rubinstein, MD, PhD, is doing biophysical
numerical simulations of the auditory nerve's response to electrical
stimulation for the development of speech processing strategies for
cochlear implants. He says that his Macintosh cluster has made a
big difference in his research.

Development Environment: Metrowerks C
This cluster is currently under construction in the Physics
Department at American University. The intended use is for Computational
Physics, Neural Networks, Fuzzy Systems, Hybrid Intelligent systems, Genetic
algorithms, Data Analysis, Applied Physics, Multimedia Development and
Audio Technology Research and Development. They hope to add new computers
by next semester.
