基于GRIDSIM的网格调度Min-Min算法改进研究

Grid-based GRIDSIM Min-Min Scheduling Algorithm to Improve Research

本文中的网格任务调度算法是在研究异构工作流系统基于OGSA网格协同任务调度的过程中,根据网格环境中资源的可用度,在特定的相依性网格任务环境下,对经典Min-Min算法进行了部分改进,提出基于资源可用度和任务相关性的相依性网格任务映射启发式算法。在作者所设计的层次网格任务调度器中得到了较好的调度效果和调度服务质量。

The grid task scheduling algorithm is in the study of heterogeneous workflow system based on OGSA Grid co-scheduling process, according to the grid environment, resource availability, in particular the task dependency grid environment, the classical Min-Min algorithm is part of the improvement is proposed based on resource availability and task dependencies task dependency mapping heuristic grid. The level of the author designed a task scheduler in the grid to get a better quality of service scheduling and dispatch results.
