耦合分布式仿真中任务调度的研究与实现

Research and Realization of Task Scheduling in Coupling Distributed System

在耦合分布式仿真系统中,为解决任务对资源合理利用的问题,采用一种First-Available调度策略,即在对资源和任务有效管理的基础上,根据工况计算任务的资源请求,在资源表中选取第一个符合要求的计算节点,指定此节点运行某项工况任务。测试表明,该调度策略能够快速有效匹配任务的资源请求,有非常强的实用价值和实效性,能够有效合理地利用资源,满足了大规模多工况多任务耦合仿真计算的要求。

In order to solve the problem of reasonable using of task for resources, a First-Available scheduling strategy is applied in the coupling distributed system, which is to compute the resource request in accordance with working condition based on effective manage- ment for resource and tasks, choosing the first available computer node and determining a certain task. The test shows that the scheduling strategy can fast effectively match task resource request, and has very highly practical value and effectiveness, can effectively and reasona- bly make use of resources ,meeting more large-scale condition multitasking coupling simulation requirements.
