GROMACS is a widely used package for biomolecular sim- ulation, and over the last two decades it has evolved from small-scale efficiency to advanced heterogeneous acceleration and multi-level paral- lelism targeting some of the largest supercomputers in the world. Here, we describe some of the ways we have been able to realize this through the use of parallelization on all levels, combined with a constant focus on absolute performance. Release 4.6 of GROMACS uses SIMD acceleration on a wide range of architectures, GPU offloading acceleration, and both OpenMP and MPI parallelism within and between nodes, respectively. The recent work on acceleration made it necessary to revisit the fun- damental algorithms of molecular simulation, including the concept of neighborsearching, and we discuss the present and future challenges we see for exascale simulation - in particular a very fine-grained task paral- lelism. We also discuss the software management, code peer review and continuous integration testing required for a project of this complexity
