Synergia simulation
<http://cepa.fnal.gov/psm/aas/Advanced_Accelerator_Simulation.html> of
the bunching phase in the Fermilab Booster Accelerator, in which 100
trillion protons are simulated using 5 million macroparticles.
Macroparticles--in this case protons with a charge of 20 million instead
of one--are used to reduce the simulation time by 100 million times, to
approximately one day. The Synergia framework can be used to submit jobs
either locally or on the grid.
Statistic of the Week
167,400
The new Internet2 Land Speed Record
<http://data-reservoir.adm.s.u-tokyo.ac.jp/lsr-20051029/sub.html> in
both the IPv6 single-
stream and multi-stream categories is 167,400 terabit-meters per second,
set by a team from the University of Tokyo, the WIDE Project and Chelsio
Communications. The team, which surpassed the previous record by 131
percent, successfully transferred data at a rate of 5.58 Gbps over a
distance of over 30,000 kilometers traversing the WIDE, IEEAF and JGN2
networks. The Internet2 LSR represents the rate at which data is
transferred multiplied by the distance traveled.

Feature Story
Sciences On The Grid

All fields of science benefit from more resources and better
collaboration, so it's no surprise that scientific researchers are among
the first to explore the potential of grid computing to connect people,
tools, and technology. Physics and biology were among the earliest
adopters, but chemistry, astronomy, the geosciences, medicine,
engineering, and even social and environmental sciences are now
kick-starting their own efforts. Here is a small sampling of some of the
projects now pushing the limits of grid computing.
Identifying Alzheimer's disease before a person exhibits symptoms;
learning the function of all the genes in the human genome; finding
drugs to cure and prevent malaria: From large dedicated biomedical
infrastructures to small individual applications, grid computing aids
scientists in their quest to solve these and other biological, medical,
and health science problems.
One of the first, and largest, of the dedicated cyberinfrastructures is
the Biomedical Informatics Research Network (BIRN). Launched in 2001,
the National Institutes of Health-funded project encourages
collaboration among scientists who traditionally conducted independent
investigations. BIRN provides a framework in which researchers pool
data, patient populations, visualization tools, as well as analysis and
modeling software.
In one of BIRN's three test beds, magnetic-resonance images from small
groups across the country are pooled to form a large population for the
study of depression, Alzheimer's disease, and cognitive impairment. A
large group of subjects makes for a very comprehensive study, but
comparing MRI scans taken at different institutions is a challenge
worthy of grid computing.

UK Engineering Task Force Evaluates GT4
Globus Toolkit
The UK Engineering Task Force recently evaluated the state of the GT4
tool kit as part of the UK e-Science Engineering Task Force activities
reviewing grid and Web service middleware for production grid deployment
within the UK e-Science community. The evaluation considered the
strengths and weaknesses of the GT4 package and identified issues that
will be important if production deployment is recommended.
The evaluation, which tracked and evaluated the development releases of
GT4, began in late November 2004 and was suspended when the last
development released was made in March 2005. The evaluation was
reactivated in May 2005 to evaluate the first full release of GT4,
create a number of large-scale GT4 applications and consider
interoperability of GT2 software and the pre-WS components in the GT4
release.
The evaluation reviewed the state of GT4 by installing the software,
reviewing available documentation, creating sample GT4 grid services and
testing inter-operation between GT2 and pre-WS GT4 components, and thus
evaluating service capabilities, documentation and the capabilities of
the software. The emphasis was on considering GT4 for large-scale
production use.
The ETF evaluation found that the GT4 toolkit release is significantly
more stable and demonstrates significantly better performance than
previous GT releases. The GT4 documentation is more comprehensive and
significantly better structured than documentation for previous GT
releases.
The Pre-WS components of GT4 provide some interoperability with GT2.4
and thus a possible migration route for GT2 code. However, the
systematic migration of the large-scale GT2 legacy investment remains a
concern to wider early adoption and deployment of GT4.

Grids, Grids Everywhere at SC|05
SC05
The Washington State Convention and Trade Center, the venue for SC|05.
Grid computing has come a long way since the first "grid," called I-WAY
for Information Wide Area Year, debuted at the 1995 Supercomputing
conference. I-WAY linked a dozen high-performance computing centers and
advanced visualization environments at speeds of up to 155 megabits per
second, and was the only grid around. This week at the Supercomputing
2005 (SC|05) conference, SCinet is providing almost one-half of a
terabit per second of network connectivity to the show floor, research
grids from the Americas, Europe and Asia are on display everywhere you
turn, and the Grid Workshop has grown so large that it will soon become
a full-fledged conference separate from Supercomputing.
SC|05, the international conference on high performance computing,
networking and storage, has taken over downtown Seattle. SC|05 posts
some impressive statistics: Over 9,250 registered attendees, requiring
1,300 gallons of coffee and 20,000 beverages; thousands of exhibitors
from research and industry; over 30% of the 165 research exhibits
showcase grid computing; 100,000s of hours of research have gone into
the technical papers being presented; 418 people attending the Grid
Workshop; and over 140 high school and undergraduate teachers are
attending this year's education program.
Grid computing at SC|05 was kicked off Sunday afternoon by the Grid 2005
Workshop keynote address. Dennis Gannon from Indiana University spoke
about lessons he's learned while building a series of grids and reviewed
the many challenges still to come in grid research. After discussing
early projects such as the I-WAY and NASA's Information Power Grid,
Gannon described the new Linked Environments for Atmospheric Discovery
project.
"LEAD is a grid designed to change the paradigm for mesoscale weather
prediction," said Gannon.
