ABSTRACT

In this paper, we propose an efficient dynamic workload balancing strategy which improves theperformance of high-performance computing system. The key idea of this dynamic workloadbalancing strategy is to minimize execution time of each job and to maximize the systemthroughput by effectively using system resource such as CPU, memory. Also, this strategydynamically allocates job by considering demanded memory size of executing job and workloadstatus of each node. If an overload node occurs due to allocated job, the proposed scheme migratesjob, executing in overload nodes, to another free nodes and reduces the waiting time and execution time of job by balancing workload of each node. Through simulation, we show that the proposeddynamic workload balancing strategy based on CPU, memory improves the performance ofhigh-performance computing system compared to previous strategies.
