The MOSIX extensions to the Linux Operating System allow the creation of high-performance Linux Farms and an excellent integration of the several CPUs of the Farm,whose computational power can be furtherly inereased and made more effective by netorking them within the GRID environment .Following this strategy,we started to perform computational tests using two independent farrms within the GRID environment.In particular,we performed a preliminary evaluation of the distributed computing efficiency with a MOSIX Linux farm in the simulation of gravitational waves data analysis from coalescing binaries.To this task,two different techniques were compared.the classical matched filters technique and one of its possible evolutions,based on a global optimisation technique.
