OO, component based, framework for molecular dynamics (MD) simulations

ProtoMol is an object-oriented, component based, framework for molecular dynamics MD simulations. The framework supports the CHARMM 19 and 28a2 force fields and is able to process PDB, PSF, XYZ and DCD trajectory files. It is designed for high flexibility, easy extendibility and maintenance, and high performance demands, including parallelization. The technique of multiple time-stepping is used to improve long-term efficiency. The use of fast electrostatic force evaluation algorithms like Ewald, particle Mesh Ewald PME, and Multigrid MG summation further enhances performance. Longer time steps are possible using MOLLY, Langevin Molly and Hybrid Monte Carlo, Nose-Hoover, and Langevin integrators. In addition, ProtoMol has been designed to interact with VMD, a visualization engine developed by the University of Illinois that is used for displaying large biomolecular systems in three dimensions. ProtoMol is freely distributed software, and the source code is available.
