NAMD, recipient of a 2002 Gordon Bell Award and a 2012 Sidney Fernbach 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 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.

Breaking News

NAMD will be used for groundbreaking coronavirus simulations that will run on the Frontera supercomputer at TACC. The Amaro Lab of UC San Diego is working to build the first complete all-atom model of the SARS-COV-2 coronavirus envelope in order to investigate how the virus interacts with receptors within the host cell membrane. The coronavirus model is anticipated to contain 200 million atoms. The simulations will run on up to 4,000 nodes or about 250,000 processing cores of Frontera.

Spotlight: VMD 1.9.3 Brings Simulations Into Focus (March 2017)

VMD 1.9.3 release incorporates QwikMD, many rendering features.

image size: 2.2MB
made with VMD

The latest release of VMD brings many advances that help researchers prepare, analyze, and visualize molecular simulations. The new QwikMD plugin streamlines key simulation preparation and analysis tasks, and guides users in the creation of reusable simulation workflows and protocols. VMD now includes several advanced features for parallel analysis and visualization of cellular-scale simulations, as reported here, and here. VMD 1.9.3 strengthens collaboration between experimental and computational biologists by supporting a broader range of experimental density map image formats, such as those used in cryo-electron tomography. Many updated plugins are included in VMD 1.9.3, including tools for analysis of free energy perturbation simulations, MDFF hybrid structure fitting, ffTK force field parameterization, and normal mode analysis. VMD 1.9.3 adds support for new hardware and operating system platforms including IBM OpenPOWER (ORNL Summit), a variety of GPU-accelerated ARM SoCs, the Amazon AWS EC2 cloud, and most recently, the Intel Xeon Phi Knight's Landing many-core CPU (TACC Stampede 2, Argonne Theta). The VMD 1.9.3 release adds stunning graphics produced using interactive ray tracing using the latest multi-core CPUs and GPU accelerators, enabling 360-degree panoramic movie rendering for VR headsets, as reported here, and here. Interactive ray tracing makes the task of getting a molecular image "just right" much easier than ever before; it also enables rendering of spectacular movies for communication of scientific results. A VR movie rendering tutorial assists users with the steps required in rendering and encoding VR movies for upload to YouTube for display using VR headsets such as Google Cardboard, Oculus Rift, and GearVR. More details about VMD 1.9.3 features can be found here.
