Proceedings1--12591 TFLOPS Multi-trillion Particles Simulation on SuperMUC2013dynamics highly molecular parallel programming scalable simulation simulations vectorization Anticipating large-scale molecular dynamics simulations (MD) in nano-fluidics, we conduct performance and scalability studies of an optimized version of the code ls1 mardyn. We present our implementation requiring only 32 Bytes per molecule, which allows us to run the, to our knowledge, largest MD simulation to date. Our optimizations tailored to the Intel Sandy Bridge processor are explained, including vectorization as well as shared-memory parallelization to make use of Hyperthreading. Finally we present results for weak and strong scaling experiments on up to 146016 Cores of SuperMUC at the Leibniz Supercomputing Centre, achieving a speed-up of 133k times which corresponds to an absolute performance of 591.2 TFLOPS.Tue Dec 12 09:47:55 CET 2017Tools for High Performance Computing 2016 2017debugging hlrs myown parallel performance programming spmt tools Fri Jan 29 09:34:55 CET 2016Facing the Multicore-Challenge III 2012September133-134LNCSPortable Codes on New HPC Architectures76862012GPU HLRS HPC Hardware Parallel Portable Programming SCOPE architecture mown myown Mon Jan 25 17:32:09 CET 2016Beijing, China44th International Conference on Parallel Processing Workshops, {ICPPW}September111-118A Bandwidth-saving Optimization for {MPI} Broadcast Collective Operation2015hlrs hpc myown parallel programming spmt Fri Nov 20 15:49:19 CET 2015Tools for High Performance Computing 2014 2015debugging hlrs myown parallel performance programming spmt tools Fri Nov 20 15:43:39 CET 20156th European Workshop on OpenMPValidating OpenMP 2.5 for Fortran and C/C++2004OpenMP hlrs myown parallel programming spmt validation Fri Nov 20 15:34:49 CET 2015Journal of Chemical Theory and Computation104455-4464ls1 mardyn: The Massively Parallel Molecular Dynamics Code for Large Systems102014MD hlrs myown parallel program programming simulation spmt Fri Nov 20 15:30:53 CET 2015Tools for High Performance Computing 2012 - Contributed Papers Presented at the 6th International Parallel Tools Workshop, Stuttgart, Germany, September 25-26, 2012DBLP:conf/ptw/201213--21Task Debugging with {TEMANEJO}2012StarSs hlrs debugging myown parallel programming spmt Fri Nov 20 15:29:32 CET 2015Applications, Tools and Techniques on the Road to Exascale Computing, Proceedings of the conference ParCo 2011, 31 August - 3 September 2011, Ghent, BelgiumDBLP:conf/parco/2011639--645{TEMANEJO} {\textendash} a debugger for task based parallel programming models2011StarSs debugging hlrs myown parallel programming spmt Fri Nov 20 15:29:04 CET 201510th {IEEE} International Symposium on Parallel and Distributed Processing with Applications, {ISPA} 2012, Leganes, Madrid, Spain, July 10-13, 2012DBLP:conf/ispa/2012743--748Avoiding Serialization Effects in Data / Dependency Aware Task Parallel Algorithms for Spatial Decomposition2012StarSs hlrs myown parallel programming spmt stencil-operations Fri Nov 20 15:25:51 CET 201510th {IEEE} International Symposium on Parallel and Distributed Processing with Applications, {ISPA} 2012, Leganes, Madrid, Spain, July 10-13, 2012DBLP:conf/ispa/201248--55Hybrid MPI/StarSs - {A} Case Study2012HPC StarSs hlrs myown parallel programming spmt Fri Nov 20 15:25:21 CET 2015J.
