Grid technology allows resource sharing among several entities, but selecting the best resource to run a specific job remains one of its main problems. The authors try to solve this problem by predicting the performance of the resources for a given job and submit user's job to best suited one. So an appropriate resource selection mechanism is crucial for the success of job execution and performance of Grid. The QoS parameter is key factor in their selection process. The QoS ensure that high quality requested jobs which may be a communicational or computational based must be submitted to high quality resources.
