Molecular Dynamics made simple

What is it?

ACEMD Platform is a complete and fast solution package, designed to run and analyze your molecular dynamics (MD) simulations. It includes ACEMD, Parameterize and HTMD packages. ACEMD is the MD engine that runs the simulation, Parameterize is a force field parameterization tool for small molecules and HTMD is a Python package that you can use to create systems, prepare them and, once ACEMD has finished simulating those systems, analyze their trajectories.


  • 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.

  • 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.

  • 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.

  • 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.


ACEMD is the next generation molecular dynamic simulation engine. It is designed to accelerate drug discovery process by providing all necessary capabilities for biomolecular simulations. It leverages the latest computing technologies, such as GPUs, and state-of-the-art computational libraries to provide outstanding simulation speed.


HTMD: A Python package to manipulate molecules

HTMD is a unique, molecular-specific, programmable environment to prepare, handle, simulate, visualize and analyze molecular systems. HTMD is written in Python, in order to allow scientists to easily extend it to their needs and use it in combination with their favorite Python libraries. With HTMD, it is possible to perform very complex protocols with just a few lines of code. With a single script, you can plan an entire computational experiment, starting with the preparation of the molecular structures and finishing with the analysis of its simulation, including calculating Markov state models, kinetic rates, affinities and binding pathways.


Acellera has developed a set of applications to prepare and analyze MD simulations that run on our drug discovery platform: PlayMolecule. You can try these applications online for free, or request a quote for local use. Learn more.
