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.

Breaking News

NAMD and VMD are part of the team winning the 2020 ACM Gordon Bell Special Prize for high performance computing-based COVID-19 research, for the paper AI-Driven Multiscale Simulations Illuminate Mechanisms of SARS-CoV-2 Spike Dynamics, presented at Supercomputing 2020, Nov 18, 2020. ACM Gordon Bell Special Prize

University of Illinois has established a oneAPI academic Center of Excellence, using oneAPI to bring its cross-architecture single programming model to NAMD in order to address exascale computing challenges of COVID-19.

NAMD is able to achieve 9x throughput with version 3.0alpha running on NVIDIA A100 GPUs. Details available on the NVIDIA developer blog.

The new NAMD reference paper has been published online. The paper provides an overview of the many features available in NAMD, its scalability on CPU and GPU platforms on system sizes of up to a billion atoms, and the recent performance enhancements for GPU accelerators.

Spotlight: Educating in Computational Biophysics: 40th Workshop Milestone (Nov 2015)

The Berkeley and Atlanta Workshops

image size: 408.8KB

The Theoretical and Computational Biophysics Group (TCBG), funded by National Institutes of Health and the National Science Foundation, is not only the developer of the widely used computational biophysics programs NAMD and VMD, but is also an ardent teacher and trainer in computational biophysics. The group has just completed its 40th hands-on computational biophysics training workshop (see complete list), having now taught over 1,200 participants in intense, face-to-face, practical training sessions in small groups, typically of 30 students. Participants are faculty, postdocs, industry professionals, and graduate students. The training material, in the form of very extensive tutorials, is freely available on the TCBG tutorial website. The workshops are continuously improved, based on participant feedback and on the evolution of NAMD and VMD. TCBG intends to continue the workshops, and is presently developing a new generation of training features built directly into NAMD and VMD in the form of the new user interface qwikMD. For more information, see the TCBG training website.
