Eric Fahrenthold and graduate student Robert Rabb in the Department of Mechanical
Engineering at the University of Texas at Austin developed this image using the
Texas Advanced Computing Center's ACES Visualization Laboratory. The image illustrates
how high-strength fabrics are used in a variety of applications to protect structures
and personnel from the effects of hypervelocity impact.

PHENIX Data Fly With GridFTP

The hunt for the quark-gluon plasma, a state of matter that may have existed in the very early universe, is getting a little help from a common grid tool. During the current run of the Relativistic Heavy Ion Collider at Brookhaven National Laboratory, the PHENIX nuclear physics experiment is using GridFTP to transfer data automatically between BNL and Vanderbilt University.
Physicists study the quark-gluon plasma and other nuclear physics phenomena by examining what happens when beams of nuclei collide in the center of the massive PHENIX detector. While identifying new states of matter requires a detailed analysis of years' worth of data, a partial analysis of each day's data gives experimenters insight into the health of the detector and of the beams, ensuring that they collect high-quality data. With PHENIX's computing resources at BNL busy analyzing previously collected data, such partial analyses must take place remotely.
"We've come to rely on these daily remote analyses for real-time data monitoring and quality assurance, and for the jump-start it gives us on our physics analysis," explains PHENIX spokesperson Bill Zajc. "Looking at the partial data sets sharpens our analysis tools, so that they are ready to be used on the full data set as soon as it is available."

| Recommended Reading for Aspiring Grid Programmers
When middleware developers write about grid, they typically describe it in very implementation-centric terms, focusing on very low-level details. When visionaries write about grid, they tend to focus on lofty concepts and future directions. So often lost in the shuffle are the novice application developers that simply want to cut their teeth and start building systems.
With the release of "Globus Toolkit 4, Programming Java Services," developers now have access to the first ever, truly developer-friendly printed guide to GT4. As Ian Foster and Carl Kesselman say in the book's foreword, "The aspiring grid programmer need be frustrated no longer. Borja Sotomayor and Lisa Childers have produced, in 'Globus Toolkit 4: Programming Java Services,' a masterly tutorial text that is surely destined to find a place beside every grid programmer's keyboard."

HawkGrid Takes Off

When scientists from The University of Iowa need extra computing power to complete an air quality simulation or test a new medical imaging algorithm, they turn to the HawkGrid. Applications from eight departments and three multi-disciplinary research centers run on this three-year-old campus grid, which contains up to 1,000 CPUs dynamically contributed by three schools and the Information Technology Services within the University.
The HawkGrid is the brainchild of Shaowen Wang, a UI research scientist. Wang was a graduate student in computer science and geography when he started learning about grid computing. In 2002, he became a staff member tasked with spearheading grid technologies on the UI campus.
"At that time there were very strong research groups all over campus that were working relatively independently," says Wang. "We found we needed to work together to increase our resources. Now anyone can bring an application to the HawkGrid, they don't need to bring resources. Applications from the physics and astronomy, geography, radiology, statistics and engineering departments now run on the HawkGrid."
