HPC系统的失效数据分析

Failure Data Analysis of HPC Systems

Charng-Da Lu

摘要:

随着系统规模增长到数千个处理器,由商用组件构建的HPC系统的持续可用性已成为主要问题。在本文中,我们提出了8-24个月的实际故障数据收集的分析,从三个HPC系统在国家超级计算应用中心(NCSA)在2001-2004年。结果表明,可用性为98.7-99.8%,大多数中断是由于软件停止。另一方面,停机时间主要是由硬件停止或定期维护造成的。我们还使用故障聚类分析,以确定几个相关的故障。

英文摘要:

Continuous availability of HPC systems built from commodity components have become a primary concern as system size grows to thousands of processors. In this paper, we present the analysis of 8-24 months of real failure data collected from three HPC systems at the National Center for Supercomputing Applications (NCSA) during 2001-2004. The results show that the availability is 98.7-99.8% and most outages are due to software halts. On the other hand, the downtime are mostly contributed by hardware halts or scheduled maintenance. We also used failure clustering analysis to identify several correlated failures.
