TY - GEN A1 - Allalen, Mohammed A1 - Brehm, Matthias A1 - Stüben, Hinnerk T1 - Performance of Quantum Chromodynamics (QCD) Simulations on the SGI Altix N2 - We study performance and scaling of the Berlin Quantum Chromodynamics Program (BQCD) on the SGI Altix 4700 at Leibniz Supercomputing Centre (LRZ). We employ different communication methods (MPI, MPI with two OpenMP threads per process, as well as the shmem library) and run the MPI version on the two types of nodes of that machine. For comparison with other machines we made performance measurements on an IBM p690 cluster and a Cray XT4.
