Benchmarking of GRID resources using the HammerCloud service — Michael Böhler, •David Hohn, Benoît Roland, Benjamin Rottler, and Markus Schumacher — Albert-Ludwigs-Universität Freiburg

The high luminosity LHC is a major upgrade to the current accelerator and will provide an order of magnitude more high energy physics data in the coming decades than exists now. To enable the analysis of this wealth of data the computing resources need to follow suit and be upgraded as well.

Reliable performance information is the foundation for planning of upgrade efforts as well as efficient operation of the complex computing systems. To this end, benchmarks provide essential insight. This talk will present fast benchmarks of CPUs which can enable prompt matching between available and required resources, as is mandatory to incorporate opportunistic and heterogeneous resources.

The benchmarks are performed by the HammerCloud service within the ATLAS GRID computing network. This constitutes an extension of the HammerCloud use cases from functional to additional performance testing.
