摘要
围绕如何在网格环境中合理调度系统资源这一目标,对实体级并行任务的动态调度问题进行了研究,设计了一种改进的启发式调度算法(阈值算法),并以舰船编队协同反潜对抗仿真系统为例,证明了该方法的可行性,该算法以次优解为目标,减少了任务的执行开销,为提高分布交互式仿真系统的资源利用效率和扩大仿真规模提供了一种可行的途径。
Aiming at how to balance load in grid environment, the dynamic scheduling of parallel tasks in entity level is investigated, and an improved threshold scheduling algorithm is presented for balancing load. The application of the algorithm to the fleet cooperative anti-submarine simulation system verifies its feasibility. This algorithm takes second optimal solution as goal to reduce executive expense of task. The method can enhance the efficiency of distributed interactive simulation and enlarge simulation scale.
