Network performance in high-performance computing environments such as supercomputers and Grid systems takes a role of great importance in deciding the overall performance of computation. However, most Job Management Systems (JMSs) available today, which are responsible for managing multiple computing resources for distribution and balancing of a computational workload, do not consider network awareness for resource management and allocation. In this paper, the authors briefly overview our proposed and prototyped network-aware JMS that can allocate an appropriate set of computing and network resources to a job request. Also, we evaluate the usefulness and effectiveness of our proposal. Experiments conducted with the prototype implementation imply that our proposed network-aware JMS could reduce job execution time by 23.4 percent.
