This mirror is a component of one of two interferometers at the Laser
Interferometer Gravitational-Wave Observatory (LIGO) Hanford Observatory
in Washington State, which operates in unison with a third interferometer at LIGO Livingston
Laboratory in Louisiana, to search for cosmic gravitational waves. At the observatories,
LIGO's 25-pound mirrors are suspended at the vertex and the ends of an L-shaped vacuum pipe
2.5 miles long on each side. Gravitational waves
produce tiny changes in the mirror positions. Laser light that travels the 2.5-mile distances
between the mirrors records these changes.

From Pakistan to Pasadena

Over the past 18 months, five students from the National University of Sciences and Technology in Pakistan have traveled to Caltech to develop their grid computing skills. The students, who have already collaborated remotely with Caltech scientists for at least one year, spend six months in California developing grid software and services.
"It's a fantastic learning experience," says Adeel Zafar, one of two NUST students currently visiting Caltech. Zafar and Atif Mehmood, both research assistants preparing to apply to graduate school, started working on grids at NUST in early 2004. They deployed a grid node for the CMS particle physics experiment, then moved to developing Web services for the Grid Analysis Environment.

"Until recently all work with NUST had been remote, through email and occasional videoconferences," says Caltech's Michael Thomas, who has worked with NUST students for over two years. "The first student came to Caltech in February 2004, and it was very beneficial. Once they're here, the communication is a lot easier and their projects move along much faster."
At NUST, a team of computer science students led by Professor Arshad Ali and graduate student Ashiq Anjum collaborates remotely with Caltech, the University of Florida and CERN in Switzerland. The students develop their software engineering skills and help scientists in the U.S. and Europe enable data analysis on the grid. One or two students are then selected to travel to Caltech under a program sponsored by both institutions, the U.S. State Department and the Ministry of Science and Technology in Pakistan.

Seismic Modeling and Oil Reservoir Simulations with TeraGrid

While oil prospecting used to rely on hunches and luck, oil companies today demand intelligent ways to surmise the geological features of the ground and choose ideal places for their equipment. Using TeraGrid resources, a multidisciplinary team—led by the University of Texas at Austin's Mary Wheeler, the Ohio State University's Joel Saltz, and Rutgers University's Manish Parashar—is at work on software tools that improve oil reservoir management.
The approach relies on subdividing a hypothetical reservoir into a mesh of blocks. Wells, pumps, and other equipment are associated with individual blocks, and an approx-
imate model of the blocks' fluid dynamics is created. Equipment is moved in order to compare the oil recovery efficiency of different con-
figurations. This process could yield billions of possible configurations, so a dynamic, data-driven optimization system narrows the field. Middleware tools manage the data produced from a rough sampling and identify starting points for more compre-
hensive searches. Dynamic steering tools allow on-the-fly searches within these subsections. Sophisticated optimization algorithms guide these searches by comparing configurations.
