ACEMD

Next Generation Molecular dynamics engine

ACEMD: MD Engine

ACEMD is a production level molecular dynamics software specially optimized to run on NVIDIA graphics processing units (GPUs) and it is one of the world’s fastest molecular dynamics engines.

This software features a powerful scripting and extension interface in Python using HTMD, allows the use of the popular CHARMM and AMBER force field formats without any change, and permits multi-host execution for replica exchange methods.

ACEMD has been used to perform molecular dynamics simulations of membrane and globular proteins, oligosaccharides, nucleic acids, and synthetic polymers.

ACEMD has provided a significant boost in performance, even a single GPU card out performs several hundred CPU-cores. With 10 cards we can easily generate microsecond level sampling in a few days.

ACEMD is an admirable molecular dynamics tool that clearly holds its promises.

L. Gauthier, Ph.D., Sanofi
Acellera and ACEMD afforded us a straightforward new tool based on its amazing MD engine performance capable to exploit fully the latest GPU hardwares. It can be easily plugged to extra codes for a maximal versatility and no doubts remains on its usefulness for an atomic scale interpretation of biomolecular NMR data and its specific spectroscopic time-scales.

O. Walker, Ph.D. and JM. Lancelin, Ph.D., University of Lyon
ACEMD is without any doubt a versatile program that exploit the full potential of MD simulations, using cost-effective hardware solutions, that can be adapted to every Molecular Modeling laboratory needs.

D. Sabbadin, Ph.D., University of Padova
The combination between ACEMD and a single GTX-780 helped us to understand discrete events happening between two metastable intermediates. The combination of MD simulations and experimental data was key to achieve our goal.
