Decentralized Job Scheduler in Desktop Grid

Desktop Grid computing are developed using different desktop Computers to benefits from idles computers in an efficient way to solve complex problems. Desktop Grid system, which connects a number of personal desktop computers, can achieve the same computing power as a supercomputer does, also with a lower cost. The goal of desktop grid system to aggregate idle computers on the network to utilize them in an efficient way. In this research we present desktop computational grid system that used to utilize desktop computers in Intranet to execute jobs in an efficient way than using a single computer. We design and implement Service Oriented Decentralized Job Scheduler (SODJS) framework based on web services technology. SODJS schedules and balances the jobs among available resources to minimize jobs response time. We evaluate SODJS performance by applying different tests. These tests show that SODJS system provides good performance compared with using single computer in terms of job execution time and system throughput.
