GROMEX / GROMEX-2

Highly Scalable Unified Long-Range Electrostatics and Flexible Ionization for Realistic Biomolecular Simulations on the Exascale

The goal of the GROMEX project is to develop a flexible, portable and ultra-scalable solver for potentials and forces within the GROMACS MD code, which is a prerequisite for exascale applications in particle-based simulations with long-range interactions in general. The second challenge is to realistically describe the time-dependent location of (partial) charges, as e.g. the protonation states of the molecules depend on their time-dependent electrostatic environment. Both tightly interlinked challenges are addressed by the implementation and optimization of a unified algorithm for long-range interactions that will account for realistic, dynamic protonation states, and at the same time overcome current scaling limitations.
