# Hardening and Development of the GROMACS Molecular Simulation Engine

> **NIH NIH R01** · UNIVERSITY OF VIRGINIA · 2020 · $11,103

## Abstract

Advances in molecular simulation methods and hardware have finally made possible to
simulate biomolecules on physiological timescales. Such simulations provide an important
tool to aid the molecular understanding of disease. However, fully integrating these new tools
into medical research requires that simulation software becomes easier to use, easier to
develop for, and more hardened, reliable and robust. Making these capabilities accessible
and reliable in the hands of a broad scientific community will require transformative gains in
reliability, interoperability, flexibility, and ease of use at scale.
 We therefore propose improvements to the open-source Gromacs molecular
simulation package to help meet these challenges. These improvements will 1) enable
automated validation of both code contributions and simulation parameter choices, 2) provide
a simple interface for external code to utilize Gromacs functionality, and 3) provide a high-
performance framework to mix Monte Carlo and molecular dynamics simulation. This work
will facilitate community extension via a robust testing framework integrated with our code
review system and via an API to allow implementation of new tools and simulations using
high-level calls. These efforts will leverage best practices from software engineering and be
implemented in a way to put tools in the hands of a broad developer and user community.
