NAMD, recipient of a 2002 Gordon Bell Award, 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 200,000 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.

The 2005 reference paper Scalable molecular dynamics with NAMD has over 1000 citations as of March 2010.

Proteins are the biological workhorses in living cells. For example, they respond to external signals arriving at the cell surface or transport cargo, much larger than themselves, from one place to another in the cell. However, before a protein can carry out his job, it must first assume the proper shape. Proteins are long polymers of twenty different amino acids linked in a linear sequence; the latter is particular for each protein. It is still a mystery how a protein folds into the proper shape based on its sequence. Scientists hope that one day they can "watch" this folding process for any given protein. The dream has been realized, at least partially, through the use of computer simulation. After tackling the protein-folding problem already computationally for two small proteins (see May 2008 highlight and Nov 2009 highlight), researchers have now successfully visualized the complete folding process of a relatively large protein, the so-called λ-repessor (see movie, 7.8 MB). In fact, it is one of the largest proteins folded to date using a computer. As reported recently, simulations carried out with the program NAMD, as well as simulations carried out on a special purpose supercomputer, Anton, achieved to follow λ-repessor's folding movement for more than 0.0001 seconds, long enough to observe the protein assume its proper shape. More information is available on our protein folding website.
