针对利用网上空闲机进行非专用机群分布式并行计算的环境,研究复杂通用网络上用什么指标发现空闲处理机及如何实时衡量处理机的负载变化以调度分配处理机。在研究现有分布式系统和专用机群负载指标的基础上,提出了一种适用于网络机群计算环境的复合型负载指标,详细讨论了它在系统中的作用和实现,并通过大量测试分析实验,得出了一个合理的负载指标更新周期。
Aiming at the environment of distributed parallel computing for non-dedicated clusters using online idle machines, this paper studies what indicators are used to find idle processors in complex general networks and how to measure load changes of processors in real time to schedule allocation processors. On the basis of studying the load indexes of existing distributed systems and private clusters, a composite load index suitable for network cluster computing environment is proposed. Its function and realization in the system are discussed in detail. Through a large number of test analysis experiments , Come to a reasonable load indicator update cycle.
