摘要
现在分布式系统中调度组件包含了预测主机负载的算法。根据这些算法得出的结果,可以看出预测的区间长度会直接影响调度结果。为此,设计了一个模拟试验,获得了预测区间长度与调度结果之间的关系,对改进调度系统中预测算法提出了一些建议。
There are many distributed systems which have the prediction algorithm to predict host load. According to the result of these algorithms, a conclusion can be gained that the interval of the prediction is the key to the result of system balance. This paper designs a simulation test and gets the relationship of the interval of prediction and the balance of the system, and gives some advices to improve the schedule algorithm of distributed system.
