Energy minimization is an important step in molecular modeling, with applications in molecular docking and in mapping binding sites. Minimization involves repeated evaluation of various bonded and non-bonded energies of a protein complex. It is a computationally expensive process, with runtimes typically being many hours on a desktop system. In the current article, we present the acceleration of the energy evaluation phase of minimization on a graphics processor, resulting in an 11x total speedup compared with a single core of a desktop machine.
