A large distributed computing environment with different groups of interest (funding agencies, resource providers, users), such as the WLCG, requires a score to define the amount of needed and provided computing resources.
The HEPiX Benchmarking Working Group has developed and provided benchmarks for high-energy physics (HEP) for years.
In addition to the classic CPU benchmark, we are...
The effective processing of experimental and simulated HEP data at scale on restrictive High Performance Computing (HPC) systems poses a known challenge to the physics communities. A significant aspect of such challenge is of technical nature. Many of the barriers have been successfully overcome or mitigated thanks to several integration projects over the last decade. Containerisation...
We built a coordinated scheduling layer across our local cluster and grid resources. Using glideins, idle grid capacity is elastically federated into our local HTCondor pool, while busy periods trigger proactive glidein removal to promptly return resources—achieving cross-domain elastic scale-out/in. On the local side, we introduced performance-aware labeling: nodes are tiered...
The BESIII experiment has been operating since 2009 and received several upgrades, to study the τ -charm physics utilizing the BEPCII accelerator. The offfine software system is the fundamental tool for physics analysis. It is developed to process the raw data from BESIII detector and Monte Carlo data from simulation,produce the reconstructed data which contains various physics information of...
AUDITOR is a flexible framework designed to address the challenges of managing large volumes of accounting data across diverse computing environments, including institute clusters, Grid sites, and Kubernetes clusters. Due to its modular design, it is possible to gather job information from various batch systems. AUDITOR effectively stores this data in a database for easy access and processing....
