基于传统的DAGs调度算法,提出了一种适于网格环境下使用的协同调度算法,目标是使得一组应用程序的整体执行时间最小,并且算法中提供了对资源的提前预约的支持。模拟结果表明,该算法与传统的调度算法相比,性能有了较大的提高。
Based on the previous DAGs scheduling algorithm, a resource co-scheduling algorithm in the Grid is presented. The goal is to minimize the overall execution time for a collection of applications. In addition,it accommodates emerging notions of advance resource reservations. Simulation results for the algorithm show a greater performance improvement over a baseline algorithm.
