Benchmarking of GRID resources and infrastructure using the HammerCloud service — •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, both in storage and processing capabilities.

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 heterogenous resources. Furthermore, benchmarks of remote storage access via several different protocols, e.g. WebDAV via Dynafed, direct WebDAV and Xrootd, will be presented. Dynafed could allow for aggregation and more efficient usage of storage resources.

Both sets of 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.
