iGrid 2002Japan

• TACC Quantum Chemistry Grid/Gaussian Portal
• National Institute of Advanced Industrial Science
  and Technology, Japan

Gaussian code, used in computational chemistry,
sometimes receives inadequate computational
resources when run on large computers. The
Gaussian Grid Portal efficiently utilizes
costly computational resources without knowing
the specifications of each system environment.
It consists of a Web interface, meta-scheduler,
computational resources, archival resources, and
Grid Infraware. Grids allow one to compute from
anywhere. 10Gb networking will eliminate the
latency of using the portal to obtain adequate
resources.

• Virtual Laboratory on a National Scale
• University of Amsterdam, The Netherlands

This demonstration of upper middleware
complements Grid services, enabling scientists to
easily extract information from raw datasets
utilizing multiple computing resources. The
Virtual Lab software assigns various clusters
(part of a distributed wide-area computer) parts
of the problem (retrieval, analysis,
visualization, etc.) To do data analysis and
visualization on a distributed system, high
bandwidth is a necessary prerequisite.

• D0 Data Analysis
• NIKHEF, The Netherlands
• Fermi National Accelerator Laboratory (Fermilab),
  USA

At D0 at Fermilab, raw data is coming from the
detector. It is processed at a computer farm at
Fermilab and the results are written to tape.
Using NetherLight/StarLight, it would be possible
to process the raw data on computers at NIKHEF.
Raw data would be transferred to NIKHEF and
results sent back to Fermilab.

• Griz Grid Visualization Over Optical Networks
• Vrije Universiteit, The Netherlands
• Electronic Visualization Laboratory, UIC

A distributed parallel rendering toolkit, Aura,
remotely renders data on available graphics
resources (notably in Chicago and Amsterdam) for
local display. Interactive and collaborative
applications have a near-real-time requirement.
For interaction over long distances, network
delay is a key factor. We expect a high-bandwidth
optical network to have a highly constant
(predictable) latency, which will make
near-real-time behavior easier.

• University College London, UK
• University of Amsterdam, The Netherlands

Very Long Baseline Interferometry (VLBI) is a
technique in which an array of physically
independent radio telescopes observes
simultaneously to yield high-resolution images of
cosmic radio sources. Today, magnetic tape
transports data from telescopes to computers. The
European VLBI Network (EVN) has access to
multiple data sources that can deliver 1Gbps each
and a data processor that can process 16 data
streams simultaneously. High-speed networks would
enable the EVN to achieve many-fold improvements
in bandwidth.

processes and systems. Understanding gene and
protein sequence information helps find new
medical drug leads. Using BICs BioGrid
(networked computational resources) and KooP

• Image Feature Extraction on a Grid Testbed
• National Center for High Performance Computing,
  Taiwan
• Institute of Statistical Science, Academia
  Sinica, Taiwan
• High Performance Computing Center, Rechenzentrum
  Universität Stuttgart

For medical imagery (confocal laser-scanning
microscopes, CT, MRI and PET), NCHC does image
processing, analysis and 3D reconstruction. For
biotechnology imagery (e.g., microarray
biochips), NCHC uses a data clustering procedure
for feature extraction that provides insight into
an image, such as identifying diseases caused by
some protein. Grid techniques enable the use of
distributed computing resources and shared data.
High-speed networks enable fast processing
typical medical doctors want the procedure
accomplished in 5 seconds for use in daily
operations.

ENZO is one of the successful parallel

in astrophysics and cosmology. We propose a
framework for dynamic load balancing on
distributed systems and implement the scheme in
ENZO code. To sufficiently simulate the formation
of galaxies, taking communication and latency
issues into consideration, the bandwidth must be
100Gbps.

time-varying datasets that are multiple terabytes
in size. In addition to supporting audio and
video, the Access Grid connects users with the
output of visualizations ? to explore datasets,
create isosurfaces, look at particle traces, and
move cutting planes. Current AG sessions consume

Logistical Networking is defined as the global
scheduling and optimization of data movement,
storage and computation. We develop tools that
are dedicated to fast data transfer, such as the
Data Mover, using as much bandwidth as is
available. For iGrid, a geographically
distributed abstraction of a file is replicated,
transported to depots that are closer according
to network proximity values calculated in
real-time using NWS, and downloaded from the
nearest site in a completely transparent way for
a high-level application.

• PAAPAB
• Res Umbrae, USA
• University at Buffalo, USA

PAAPAB (Pick An Avatar, Pick A Beat) is a shared
virtual-reality disco environment inhabited by
life-size puppets (user avatars). Currently, due
to limited bandwidth, the disco motions and music
are cached and played back locally at each client
rather than streamed continuously. Our
theoretical bandwidth needs are in the 50-100
Mbps range (for up to 12 participants, 40
puppets, and high-quality audio). Assuming 10Gb,
the limiting factor becomes the number of people
who have access to VR equipment and network
connections. Of course, latency and jitter are
also issues to understand.

Approximately 10000 scientists from 100s of

Collider (LHC) data. To make processing the data
efficient, it might be desirable to create remote

(files) to reduce access latency, increase
robustness, or increase the probability that a
file can be found associated with idle computing
capacity. Tools that accomplish this are
presented GridFTP (a transport mechanism for
moving the data over the WAN), a replica location
service (RLS), and GDMP (a simple, high-level
