Abstract

Supercomputer job management systems (JMS) are complex software which have a number of parameters and settings. Various simulating methods have been used in order to explore impact of such parameters on the JMS efficiency metrics. At the same time evaluating accuracy (adequacy) of the applied JMS models is one of the key points. The paper contains the results of adequacy measure experiments for various JMS models, including simulating with a virtual supercomputing nodes and with the Alea job scheduling simulator. JMS SUPPZ functioning at the Joint Supercomputer Center of the Russian Academy of Sciences (JSCC RAS) was used for the experiments. Source data for such simulating was created upon the statistics of supercomputer MVS–10P OP installed at JSCC RAS. The normalized Euclidean distance between the job residence (turnaround) time vectors, obtained from the job streams of the real supercomputer and JMS model, was used as a measure of adequacy. The experiments results have confirmed intuitive ideas about the studied simulating methods accuracy, that allows using the normalized Euclidean distance between the jobs turnaround times vectors as a measure of various JMS models adequacy.

各种超级计算机作业管理系统模型精度对比

摘要

超级计算机作业管理系统 (JMS) 是具有许多参数和设置的复杂软件。已使用各种模拟方法来探索此类参数对 JMS 效率指标的影响。同时评估应用的JMS模型的准确性（充分性）是关键点之一。该论文包含各种 JMS 模型的充分性测量实验结果，包括使用虚拟超级计算节点和 Alea 作业调度模拟器进行模拟。在俄罗斯科学院联合超级计算机中心 (JSCC RAS) 运行的 JMS SUPPZ 用于实验。这种模拟的源数据是根据安装在 JSCC RAS 的超级计算机 MVS-10P OP 的统计数据创建的。工作地点（周转）时间向量之间的归一化欧几里得距离，从真实超级计算机和 JMS 模型的作业流中获得，被用作充分性的衡量标准。实验结果证实了关于所研究的模拟方法准确性的直观想法，允许使用作业周转时间向量之间的归一化欧几里得距离作为各种 JMS 模型充分性的度量​​。
