针对网格计算中的工作流
大部分只考虑DAG(Directed Acyclic Graph)工作流调度模型
本文对于含有更复杂的工作流结构(如循环、并行、分支等)进行了研究
并提出了一种任务优先级调度策略
用循环并行算法(LOOP-PARAL)解决了含有循环结构的网格工作流的任务调度问题
在满足用户QoS(Quarlity of Service)需求的同时
使系统的负载更加平衡
更加适合开放复杂的网格环境
提高了系统的性能.仿真实验证明了该算法的合理性和有效性.
Regarding workflow scheduling in grid computing
most research consider the model of DAG(Directed Acyclic Graph).In this paper
we consider more complicated workflow structure(e.g.loop
parallel
and pipeline) and propose a scheduling strategy based on task priority.The algorithm called LOOP-PARAL solves the task scheduling which contain a loop structure.The algorithm
on one hand
satisfies the user’s QoS(Quality of Service)
on the other hand
it makes more balance of the load.The algorithm improves the system quality and fits more complex grid environment.Experimental results show that the algorithm is more reasonable and efficient.
