卫星数据分布式处理平台中并行调度技术的研究

摘要

由于卫星数据处理的特殊性，现有的任务调度算法均无法取得良好的效果。针对上述问题，本文对卫星数据分布式处理平台中的任务调度进行了深入研究，提出了资源槽的概念，并在此基础上提出了基于资源槽的并行调度技术。实验表明，采用基于资源槽的并行调度技术，极大地提高了系统资源的利用率和任务的响应速度，并有效改善了系统负载的均衡性。%Due to the particularity of satellite data, the existing task scheduling algorithm can not achieve good results. To solve the above problem, in this paper, the task scheduling of the satellite data distributed processing platform is studied, and the concept of resource slot is put forward. And a parallel scheduling technique based on resource slot is proposed. Experiments show that the use of resource slot in parallel scheduling technology, has greatly improved the utilization of system resources and the corresponding task speed, and effectively improved the system load balance.
