NAMD, recipient of a 2002 Gordon Bell Award, a 2012 Sidney Fernbach Award, and a 2020 Gordon Bell Prize, is a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems. Based on Charm++ parallel objects, NAMD scales to hundreds of cores for typical simulations and beyond 500,000 cores for the largest simulations. NAMD uses the popular molecular graphics program VMD for simulation setup and trajectory analysis, but is also file-compatible with AMBER, CHARMM, and X-PLOR. NAMD is distributed free of charge with source code. You can build NAMD yourself or download binaries for a wide variety of platforms. Our tutorials show you how to use NAMD and VMD for biomolecular modeling.

made with VMD
The 2.12 release of the molecular dynamics program NAMD provides major enhancements in performance, flexibility, and accuracy, complementing the greatly enhanced usability provided by the QwikMD GUI released in VMD 1.9.3. NVIDIA GPU-accelerated simulations with NAMD 2.12 are up to three times as fast as 2.11, particularly for implicit solvent simulations and single-node simulations of smaller systems. NAMD 2.12 is also optimized for the new Intel Xeon Phi KNL processors found in Argonne Theta, NERSC Cori, and TACC Stampede 2. NAMD 2.12 builds on the asynchronous multi-copy scripting capabilities introduced in NAMD 2.11 with the ability to modify and reload the molecular structure, enabling development of grand canonical and constant pH ensemble methods, as well as an optional Python interface for advanced on-the-fly analysis. Finally, NAMD 2.12 provides a complete, no-recompilation-needed interface for hybrid QM/MM with both the semi-empirical code MOPAC and the ab initio/DFT code ORCA. More on new features in the 2.12 release of NAMD can be found here. NAMD is available free-of-charge as source code, precompiled binaries, pre-installed at supercomputer centers, and now jointly with VMD as one-click interactive molecular modeling on the Amazon cloud.
