The Technology Watch Working Group, established in 2018 to take a close look at the evolution of the technology relevant to HEP computing, has resumed its activities after a long pause. In this report, we provide an overview of the hardware technology landscape and some recent developments, highlighting the impact on the HEP computing community.
This study presents analyses of natural job drainage and power reduction patterns in the PIC Tier-1 data center, which uses HTCondor for workload scheduling. By examining historical HTCondor logs from 2023 and 2024, we simulate natural job drainage behaviors, in order to understand natural job drainage patterns: when jobs naturally conclude without external intervention. These findings provide...
The CERN Cloud Infrastructure Service provides access to large compute and storage resources for the laboratory that includes virtual and physical machines, volumes, fileshares, loadbalancers, etc. across 2 different datacenters. With the recent addition of the Prevessin Data Center, one of the main objectives of the CERN IT Department is to ensure that all services have up-to-date procedures...
The objective of this talk is to share the tentative plan of energy efficiency status review by the TechWatch WG. Progress of the primary tasks such as reviewing and understanding of the trends of industry, market and technology, efforts of WLCG and sites, as well as the strategy from measurement/ data collection/ analysis/ modeling/ to estimation will be shared. Through this report, the...
Extending the data presented at the last few HEPiX workshops, we present new measurements on the energy efficiency (HEPScore/Watt) of the recently available AmpereOne-ARM and AMD Turin-x86 machines.
In this presentation we try to give an update on CPU, GPU and AI accelerators in the market today.
