摘要

在集群或网格计算系统中寻找最小负载节点的任务是负载平衡和调度算法所必需的。因此,这些算法中的lint步骤通常是预测每个系统节点上新任务的CPU分配或可用性(与其工作负载成反比)。本文介绍了DYPAP监测仪;一种实时监控工具,负责定期描述节点状态,并利用这些信息计算动态流程分配预测(DYPAP)模型。该模型的目标是通过测量来预测工作站的CPU分配,而无需先验地了解其状态。通过大量的实验验证了DYPAP模型,并对各种情况下的监测性能进行了评估。

Estimating a workstation CPU assignment with the DYPAP monitor
The task of finding the least loaded node on a cluster or Grid computing system is necessary in load balancing and scheduling algorithms. Therefore, the lint step in these algorithms is usually a prediction of the CPU assignment or availability for a new task on each system node (inversely related to its workload). This paper presents the DYPAP monitor; a real-time monitoring utility responsible for periodically characterizing a node state and computing with this information the dynamic process assignment prediction (DYPAP) model. The goal of this model is to predict the CPU assignment of a workstation from measurements, without a priori knowledge about its state. An extensive set of experiments is presented to validate the DYPAP model and to evaluate the monitor performance in all kind of situations.
