分析了网格任务调度中经典的Max-Min算法,在此基础上充分考虑了服务质量(QoS)对任务调度的影响,并结合执行成本概念,提出了一个基于QoS约束的网格任务分组调度算法——MOS算法,目的是追求任务的高执行效率和使用者的低使用成本。%After analysis of the classical Max-Min algorithm and consideration of the effect of QoS on task sched-uling and of running cost, a algorithm for task scheduling in grid based on QoS, makespan oriented scheduling algo-rithm(MOS), is put forward to maximize efficiency and minimize cost.
