The Theoretical Biophysics Group at the University of Illinois is proud to announce the public release of a new version of NAMD, a parallel, object-oriented molecular dynamics code designed for high-performance simulation of large biomolecular systems. NAMD is distributed free of charge and includes source code. NAMD development is supported by the NIH National Center for Research Resources.

NAMD 2.3b1 has several advantages over NAMD 2.2:

- The new psfgen tool for building PSF structure files.

- Simpler to run on a single workstation. (No more rsh!)

- New ports to the Compaq AlphaServer SC and Scyld Beowulf.

NAMD is available from http://www.ks.uiuc.edu/Research/namd/.

The Theoretical Biophysics group encourages NAMD users to be closely involved in the development process through reporting bugs, contributing fixes, periodical surveys and via other means. Questions or comments may be directed to namd@ks.uiuc.edu.

We are eager to hear from you, and thank you for using our software!
