HEPScore is a new CPU benchmark created to replace the HEPSPEC06 benchmark
that is currently used by the WLCG for procurement, computing resource pledges
and performance studies. The development of the new benchmark, based on HEP
applications or workloads, has involved many contributions from software
developers, data analysts, experts of the experiments, representatives of
several WLCG computing centres, as well as the WLCG HEPScore Deployment Task
Force. In this contribution, we review the selection of workloads and the
validation of the new HEPScore benchmark.Comment: Paper submitted to the proceedings of the Computing in HEP Conference
