Integrating LHCb Offline Workflows on Supercomputers State of Practice / Boyer, Alexandre F (CERN) ; Stagni, Federico (CERN) ; Haen, Christophe (CERN) ; Burr, Christopher (CERN) ; Romanovskiy, Vladimir (Kurchatov Inst., Moscow) ; Bozzi, Concezio (INFN, Ferrara)
To better understand experimental conditions and performances of its experiment, the LHCb collaboration executes tens of thousands of looselycoupled and CPU-intensive Monte Carlo simulation workflows per hour. To meet the increasing LHC computing needs, funding agencies encourage the collaboration to exploit High-Performance Computing resources, and more specifically supercomputers, which offer a significant additional amount of computing resources but also come with higher integration challenges.

Study of ATLAS TRT performance with GRID and supercomputers. / Krasnopevtsev, Dimitriy (National Research Nuclear University MEPhI) ; Klimentov, Alexei (Brookhaven National Laboratory (BNL)) ; Belyaev, Nikita (National Research Nuclear University MEPhI) ; Mashinistov, Ruslan (P.N. Lebedev Institute of Physics) ; Ryabinkin, Evgeny (NRC Kurchatov Institute Tier site)
After the early success in discovering a new particle consistent with the long awaited Higgs boson, Large Hadron Collider experiments are ready for the precision measurements and further discoveries that will be made possible by much higher LHC collision rates from spring 2015. A proper understanding of the detectors performance at highoccupancy conditions is important for many on-going physics analyses. [...]

Integration of the Chinese HPC Grid in ATLAS Distributed Computing / Filipcic, Andrej (Jozef Stefan Institute and University of Ljubljana, Department of Physics) /ATLAS Collaboration
Fifteen Chinese High Performance Computing sites, many of them on the TOP500 list of most powerful supercomputers, are integrated into a common infrastructure providing coherent access to a user through an interface based on a RESTful interface called SCEAPI. These resources have been integrated into the ATLAS Grid production system using a bridge between ATLAS and SCEAPI which translates the authorization and job submission protocols between the two environments.
