ACEMD is a production molecular dynamics software specially optimized to run on NVIDIA graphics processing units (GPUs). ACEMD is the world’s fastest molecular dynamics engine for a single workstation and can read the popular CHARMM and AMBER force field formats without any change. 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.Use cases Contact us
