许多研究机构都在部署基于共享/买入模式的计算集群。这样的集群结合了共享计算机和买入计算机,共享计算机可供所有用户免费使用,而买入计算机是用户为半排他用途而购买的计算机。本文的目的是使用波士顿大学共享计算集群(SCC)的数据跟踪作为案例研究,来表征共享/买入计算集群的典型行为和性能。在我们的主要发现中,我们发现半排他策略允许任何SCC用户在有限的时间内使用空闲的买入资源,使买入资源的利用率提高了17.4%,从而显著提高了系统的整体性能。我们发现,与其他作业相比,允许在空闲买入资源上运行的作业到达的频率更高,运行的时间更短。最后,我们将运行时间限制(即允许作业使用资源的最长时间)和并行环境类型确定为对共享作业和买入作业体验的不同性能有显著影响的两个因素。
Many research institutions are deploying computing clusters based on a shared/buy-in paradigm. Such clusters combine shared computers, which are free to be used by all users, and buy-in computers, which are computers purchased by users for semi-exclusive use. The purpose of this paper is to characterize the typical behavior and performance of a shared/buy-in computing cluster, using data traces from the Shared Computing Cluster (SCC) at Boston University that runs under this paradigm as a case study. Among our main findings, we show that the semi-exclusive policy, which allows any SCC user to use idle buy-in resources for a limited time, increases the utilization of buy-in resources by 17.4%, thus significantly improving the performance of the system as a whole. We find that jobs allowed to run on idle buy-in resources arrive more frequently and run for a shorter time than other jobs. Finally, we identify the run time limit (i.e., the maximum time during which a job is allowed to use resources) and the type of parallel environment as two factors that have a significant impact on the different performance experienced by shared and buy-in jobs.
