论文摘要
WLCG中CPU资源的基准测试基于HEP-SPEC06(HS06)套件已有十多年了。最近很明显,基于非HEP域的真实应用的HS06不再描述典型的HEP工作负载。 HEP基准项目的目的是基于LHC实验的实际应用,为WLCG计算资源开发新的基准套件。因此,通过构造,这些新的基准可以保证与HEP应用程序的吞吐量高度相关,并且CPU使用模式与它们的使用模式相似。 Linux容器和CERNVM-FS文件系统是实现这种方法的两种主要技术,过去被认为是不可能的。在本文中,我们回顾了新基准套件的动机,实施和前景。
Benchmarking of CPU resources in WLCG has been based on the HEP-SPEC06 (HS06) suite for over a decade. It has recently become clear that HS06, which is based on real applications from non-HEP domains, no longer describes typical HEP workloads. The aim of the HEP-Benchmarks project is to develop a new benchmark suite for WLCG compute resources, based on real applications from the LHC experiments. By construction, these new benchmarks are thus guaranteed to have a score highly correlated to the throughputs of HEP applications, and a CPU usage pattern similar to theirs. Linux containers and the CernVM-FS filesystem are the two main technologies enabling this approach, which had been considered impossible in the past. In this paper, we review the motivation, implementation and outlook of the new benchmark suite.
