ABSTRACT:
We present performance and scaling of all-atom molecular dynamics (MD) simulation of multimillion-atom biological systems. These simulations are limited by the parallel efficiency of the MD algorithms. Highly tuned SSE compute kernels enable node performance similar to GPU performance. The bottleneck for highly-parallel all-atom simulations is the computation of the electrostatic interactions. Shown is the scaling of MD using the reaction field method to the full Jaguar XT5 size. We present also a new highly-scalable Particle Mesh Ewald decomposition.
