Description

HEPscore is a CPU benchmark, based on HEP applications, that the HEPiX Working Group is proposing as a replacement of the HEPSpec06 benchmark (HS06), which is currently used by the WLCG for procurement, computing resource requests and pledges, accounting and performance studies. At the CHEP 2019 conference, we presented the reasons for building a benchmark for the HEP community that is based on HEP applications instead of standard industrial benchmarks. In this contribution we describe the mix of HEP workloads selected to build HEPscore. We present the results of the 2022 campaign of measurements that studied the performance of eleven HEP applications on more than 70 unique computer systems on multiple WLCG sites. We provide an update on the current status of a HEPScore candidate and its deployment plans for 2023. We also discuss how HEPscore can be used to assess the power efficiency of different CPU architectures.
