GridPP is a collaboration of particle
physicists and computer scientists from the UK and CERN, the European Organization for Nuclear
Research.
GridPP is building a distributed computing grid across the UK for particle physicists, which
currently includes 17 institutions.
When the Large Hadron Collider, the world’s largest particle accelerator, opens at CERN
in 2007 several grids around the world will be used to process the accompanying data deluge. GridPP will
contribute the equivalent of 10,000 PCs to this worldwide effort.

The peak performance of CrimsonGridBGL, the largest IBM Blue Gene Supercomputer in U.S.
academia, is 11 trillion floating point calculations per second.
The system will be part of the Crimson Grid, Harvard University's campus grid.

Probing the Perfect Liquid with the STAR Grid
Schematic of the collision zone between two incoming nuclei. |
Microseconds after the Big Bang, the universe consisted only of a soup of free quarks and gluons. Experiments at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory seek to reproduce this soup—called the quark-gluon plasma—by creating "little bangs" from high-energy collisions of heavy nuclei. The Open Science Grid's software stack helps the STAR experiment study the quark-gluon plasma in the laboratory by bringing its far-flung computing resources into a uniform environment.
Recent findings from STAR and other experiments have shown that the quark-gluon plasma behaves like an extraordinarily perfect liquid that flows with little resistance. To measure the properties of this perfect liquid, physicists must sift through the ashes from millions of little bangs, or collisions of two nuclei. One quantity that can reveal the properties of matter at these very small scales is the "elliptic flow" of particles in the STAR detector.
"When two heavy nuclei collide in the center of the detector, the initial shape of the collision zone is usually an ellipse," explains James Dunlop from Brookhaven National Laboratory. "Pressure in the liquid seeks to make the matter round, and so makes the liquid flow faster in the shorter direction."

$3.2M Grant to Bolster Campus Info System
The UCSD Gazette, October 24, 2006
By Casey Lo
UCSD’s Pacific Rim Application and Grid Middleware Assembly, an internationally uniform grid system that connects the United States and 10 participating Pacific Rim countries to encourage collaborative scientific research, has recently been endowed with a $3.2 million grant to expand its worldwide scientific application systems.

Intelligent sensors gear up for real-time flood monitoring
UK E-Science Press Release, October 18, 2006
An intelligent flood monitoring system that could give advance warning of the type of rapid flood that engulfed the UK Cornish village of Boscastle in 2004, is under test in the Yorkshire Dales.

U.S. Grid Funding Roundup
The last two months have seen a flurry of grid computing-
related funding announcements from
the National Science Founda-
tion and the U.S. Department of Energy. The following is a
quick guide to some of the recent awards.
The second
round of the DOE's Scientific
Discovery through Advanced Computing program, known as SciDAC-2, included significant funding
for several grid and cyberinfrastructure-related projects. Petascale is the buzzword of
the SciDAC-2 program, which includes awards to the Center for Enabling Distributed Petascale
Science and the Petascale Data Storage Institute. A project to scale the Earth System Grid to a Petascale
Data Center also received funding, and the DOE joined with the NSF to support the Open Science
Grid.
The NSF's most recent awards include support for cyberinfra-
structure educa-
tion, outreach,
career training and global collaboration. The Pacific Rim Applications
and Grid Middleware Assembly and the Open Science Grid both received grants to
broaden their scientific impact. An award to the Texas Advanced Computing Center for a new
high-performance computing system will further enhance the TeraGrid infrastructure.
The NSF also continues to support the training
of the next generation of cyberinfrastructure workers with its new round of CI-TEAM awards,
including implementation projects focusing on engineering, civil infrastructure, citizen
scientists and global collaboration.
For more information about these and other awards, please visit the DOE and NSF Web sites.
