Domenico Giordano summarises the plans for the adoption of the new HEPScore benchmark in WLCG.
The workloads considered for the first official version (HS23) are from ATLAS, ALICE, CMS, LHCb and
Belle II and the score will be normalised to be the same as HS06 on the reference server, to make the
transition easier for the accounting system. The supported architectures are x86 and ARM and the score
has been shown to be reproducible at the per-mille level. The goal is to have HS23 in production by 1 April.
ARM support will be included in the first version only if all the workloads will be ready by 14 February. Sites
will not be required to re-benchmark already deployed hardware, but they may choose to do it.
The following comments are noted:
• James Letts asks for more details about the procedure to update a workload. Domenico explains
that a change should be requested by the experiment contact in the HEPScore Task Force and
Simone adds that updates in HEPScore should not happen too frequently, to be manageable for
the infrastructure. Simone proposes that, whenever an experiment believes that an update to
HEPScore is needed, they should submit the request to the MB, which will then task the relevant
experts with understanding costs and benefits. Simone’s proposal is accepted by the MB.
• Elizabeth Sexton-Kennedy asks if HEPScore might be used also to pledge fractions of HPC
facilities using ARM rather than only for traditional Tier-1/2 sites. Simone replies that today we do
not have a model to pledge a fraction of an HPC, but this might happen in the future and HEPScore
should then be re-evaluated to accommodate this case.
The Management Board gives its green light for the plan outlined by Domenico
