ACEMD is a production molecular dynamics software specially optimized to run on NVIDIA graphics processing units (GPUs). ACEMD is the first accelerated molecular dynamics engine designed to run on a single GPU, on large cluster infrastructure, and also in the AWS Cloud. Its versatility allows it to read the popular CHARMM and AMBER force field formats. ACEMD features a powerful scripting and extension interface in Python using HTMD, and permits multi-host execution for replica exchange methods. ACEMD has been used to perform molecular dynamics simulations of proteins, oligosaccharides, nucleic acids, and synthetic polymers.
