Description
The standard procedures for the extraction of gravitational wave signals coming
from coalescing binaries provided by the output signal of an interferometric
antenna may require computing powers generally not available in a single computing
centre or laboratory. A way to overcome this problem consists in using the
computing power available in different places as a single geographically
distributed computing system. This solution is now effective within the GRID
environment, that allows distributing the required computing effort for specific
data analysis procedure among different sites according to the available computing
power.
Within this environment we developed a system prototype with application software
for the experimental tests of a geographically distributed computing system for the
analysis of gravitational wave signal from coalescing binary systems. The facility
has been developed as a general purpose system that uses only standard hardware and
software components, so that it can be easily upgraded and configured. In fact, it
can be partially or totally configured as a GRID farm, as MOSIX farm or as MPI
farm. All these three configurations may coexist since the facility can be split
into configuration subsets. A full description of this farm is reported, together
with the results of the performance tests and planned developments.
