The goal of the workshop is to define the strategy for the adoption of HEPscore as replacement of HepSpec06.
The HEPSpec06 benchmark has been a reliable estimate of CPU performance for many years, and is currently used by the WLCG for accounting and pledges. However, HEPSpec06 is based on the SPEC2006 benchmark that is no longer supported. Further, it uses applications that do not reflect those used by the HEP community and will not provide benchmark for the new CPU+GPU systems.
The HEPscore Workshop will consist of several sessions:
Monday September 19
The first session will summarize the work of the WLCG HEPscore Task Force and the HEPiX Benchmark Working Group. During the session, potential candidates for the new HEPScore22 benchmark will be introduced.
The second session is devoted to the presentation of the current HEP-Workloads provided in the past year by the LHC experiments, Belle2, Juno and IWGN. Besides a description of the applications and of their performance, representatives of each experiment will highlight their expectations about the HEPscore22 composition and its lifetime.
The last session will introduce the framework developed to run HEP benchmarks and collect benchmark measurements ensuring traceability and monitoring. The HEP Benchmark Suite will be described and feedback about its usability will be provided by WLCG sites having used the suite.
Tuesday September 20
The morning session will focus on the policy and strategy foreseen to evolve from HepSpec06 to HEPscore, and the implications to accounting, pledging and procurement. The session will start with presentations from members of the Accounting Task Force, regarding the status of the development and the proposed deployment strategies. A round table with all the stakeholders will follow the presentations.
The last session is named "beyond x86". It will cover R&D work done by the Benchmarking Working Group in the area of heterogeneous computing, in order to extend HEPScore also to the benchmarking of servers with GPUs. In addition, there will be presentations on CPU power consumption and its relation to HEPScore.
