ABSTRACT
Distributed computing system has been used as a tool to solve many large-scale parallel computational problems. However, due to the heterogeneity of the resources as well as applications, most of the dependent parallel tasks are not able to complete at the same time. If the waiting time for task processing increases, overall performance can be degraded significantly cause by the synchronization between parallel tasks. This research proposes a central processing unit (CPU) Utilization Control system, which is able to throttle the CPU usage by periodically, forces the associated processes to be idle for a short time. The released CPU power then can be allocated for other local jobs without scarifying the performance of dependent tasks.
