CPU utilization, throughput, turnaround time, waiting time, and response time are the factor to
influence system performance. Every system uses different scheduling algorithms to achieve his
goal. In the grid computing, resources usages are important to get good performance . When jobs
are not uniformly distributed in all grid nodes, job scheduling is more important . In order to achieve
performance optimization, we propose a Maximum Processor Utilization and Minimum Turnaround  
Time (MPUMTT) scheduling algorithm which maximizes CPU utilization and minimizes turnaround
time as well. The algorithm is used in all execute grid nodes to schedule their jobs and get good
