Scientists Achieve World's Largest Molecular Dynamics Simulation

Molecular Dynamics (MD) Simulation has become a recognized tool in engineering and natural sciences, complementing theory and experiment. Despite its development for over half a century, scientists still quest for ever larger and longer simulation runs to cover processes on greater length and time scales. Due to the massive parallelism MD typically exhibits, it is a preeminent task for high-performance computing. Thanks to the vast computing power of GCS system SuperMUC, installed at LRZ Garching, a new world record in molecular dynamics simulation of particles was achieved. A team of scientists from the LRZ, HLRS, Technische Universität München, the laboratories of Thermodynamics at Technische Universität Kaiserslautern and Universität Paderborn were able to simulate the behaviour of more than four trillion (4.125*1012) particles, which is a four-fold increase over the previous record.
