Project: Laser Gravitational Wave Observatory

Description: LIGO (Laser Interferometer Gravitational-Wave Observatory) is a distributed network of three-km-scale interferometers occupying two sites in the U.S. The construction project was funded by NSF and jointly built by Caltech and MIT. The LIGO Scientific Collaboration is the scientific body organized to use the instrumentation as a national resource. The observatoryÕs mission is to detect and measure gravitational waves predicted by general relativity, Einstein's theory of gravity, in which gravity is described as due to the curvature of the fabric of time and space. LIGO has built a specialized Lighweight Data Replicator build entirely on Globus Toolkit technologies. They are using the software to move data off of the detectors and to replicate it among interested sites.

Participants: Caltech, MIT, UWM, UT Brownsville

Sponsors: National Science Foundation

Countries Involved: US

Tools: All components of Globus Toolkit 2.x are in use.
