poster presentation Track8: Performance increase and optimization exploiting hardware features

The Piz Daint Cray XC30 HPC system at CSCS, the Swiss National Supercomputing centre, is in 2014 the highest ranked European system on TOP500, also featuring GPU accelerators. Event generation and detector simulation for the  ATLAS experiment has been enabled for this machine. We report on the technical solutions, performance, HPC policy  challenges and possible future opportunities for HEP on extreme HPC systems. In particular a custom made  integration to the ATLAS job submission system has been developed via the Advanced Resource Connector (ARC) middleware. Further, some GPU acceleration of the GEANT4 detector simulations were implemented to justify the allocation request for this machine.
