A Job Scheduling Policy Used to Minimize the Mean Response Time of the un-Real Time Jobs in the Multi- Heterogeneous Clusters
异构机群下最小化非实时任务平均响应时间的调度策略

Clusters are more and more popular being used as the high performance computing platform. Clusters need to connected together to form a much stronger integrated computing system to fulfill the request of the applications. The jobs which are processed by the system are divided into two main kinds, refered as real-time jobs and un-real-time jobs, and each can be further divided into data related jobs and un-data related jobs. This paper address on processing of the un-real-time jobs without data relationships. And made the goal function as the minimizing the mean response time. Some of the existed polices are not suited in the multi-heterogeneous-clusters, others are lack of communication cost considering, or both. This paper propose a job scheduling policy to solve those problem without increasing the additional system cost.
