Abstract

We have developed a simple and robust system based on standard UNIX tools and frame library code to transfer and merge data from multiple gravitational wave detectors distributed worldwide. The transfer and merger take place with less than 20 minute delay and the output frames are available for all participants. Presently VIRGO and LIGO participate in the exchange and only environmental data are shared. The system is modular to allow future improvements and the use of new tools like Grid.
