Editing Molecular Modeling

* [http://www.gromacs.org/ GROMACS] - is a versatile package to perform molecular dynamics, i.e. simulate the Newtonian equations of motion for systems with hundreds to millions of particles. It is primarily designed for biochemical molecules like proteins and lipids that have a lot of complicated bonded interactions, but since GROMACS is extremely fast at calculating the nonbonded interactions (that usually dominate simulations) many groups are also using it for research on non-biological systems, e.g. polymers.
* [http://www.ks.uiuc.edu/Research/namd/ NAMD] is a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems. NAMD scales to hundreds of processors on high-end parallel platforms, as well as tens of processors on low-cost commodity clusters, and also runs on individual desktop and laptop computers. NAMD works with AMBER and CHARMM potential functions, parameters, and file formats.
* [http://deshawresearch.com/resources.html Desmond] is a software package developed at D. E. Shaw Research to perform high-speed molecular dynamics simulations of biological systems on conventional commodity clusters. The code uses novel parallel algorithms and numerical techniques to achieve high performance and accuracy on platforms containing a large number of processors, but may also be executed on a single computer.
* [http://charm.cs.uiuc.edu/OpenAtom/ OpenAtom] is a highly scalable and portable parallel application for molecular dynamics simulations at the quantum level. It implements the Car-Parrinello ab-initio Molecular Dynamics (CPAIMD) method. OpenAtom is written using the [http://charm.cs.uiuc.edu/ Charm++] parallel programming framework. It runs on a variety of architectures like PowerPC, Opteron and Intel-based systems.
*[http://www.scripps.edu/mb/olson/doc/autodock/ AutoDock] is a suite of automated docking tools. It is designed to predict how small molecules, such as substrates or drug candidates, bind to a receptor of known 3D structure. AutoDock actually consists of two main programs: AutoDock performs the docking of the ligand to a set of grids describing the target protein; AutoGrid re-calculates these grids. In addition to using them for docking, the atomic affinity grids can be visualised. This can help, for example, to guide organic synthetic chemists design better binders.
*[http://lammps.sandia.gov/ LAMMPS] LAMMPS is a classical molecular dynamics code that models an ensemble of particles in a liquid, solid, or gaseous state. It can model atomic, polymeric, biological, metallic, granular, and coarse-grained systems using a variety of force fields and boundary conditions. LAMMPS runs efficiently on single-processor desktop or laptop machines, but is designed for parallel computers. It will run on any parallel machine that compiles C++ and supports the MPI message-passing library. This includes distributed- or shared-memory parallel machines and Beowulf-style clusters.

-*[http://www.cpmd.org/ CPMD] is a parallel plane wave / pseudopotential implementation of Density Functional Theory, particularly designed for ab-initio molecular dynamics.
-*[http://cp2k.berlios.de/ CP2K] is a freely available (GPL) program, written in Fortran 95, to perform atomistic and molecular simulations of solid state, liquid, molecular and biological systems. It provides a general framework for different methods such as e.g. density functional theory (DFT) using a mixed Gaussian and plane waves approach (GPW), and classical pair and many-body potentials.
