The performance score per CPU core — corepower — reported annually by WLCG sites is a critical metric for ensuring reliable accounting, transparency, trust, and efficient resource utilization across experiment sites. It is therefore essential to compare the published CPU corepower with the actual runtime corepower observed in production environments. Traditionally, sites have reported annual...
Developments in microprocessor technology have confirmed the trend towards higher core-counts and decreased amount of memory per core, resulting in major improvements in power efficiency for a given level of performance. Per node core-counts have increased significantly over the past five years for the x86_64 architecture, which is dominating in the LHC computing environment, and the higher...
The Benchmarking Working Group (WG) has been actively advancing the HEP Benchmark Suite to meet the evolving needs of the Worldwide LHC Computing Grid (WLCG). This presentation will provide a comprehensive status report on the WG’s activities, highlighting the intense efforts to enhance the suite’s capabilities with a focus on performance optimization and sustainability.
In response to...
Many efforts have tried to combine the HPC and QC fields, proposing integrations between quantum computers and traditional clusters. Despite these efforts, the problem is far from solved, as quantum computers face a continuous evolution. Moreover, nowadays, quantum computers are scarce compared to the traditional resources in the HPC clusters: managing the access from the HPC nodes is...
