It's been a long time coming, but 2.6b1 is ready to go. This is a beta,
so be on the lookout for bugs. I've added a page to the NamdWiki at so
please check that page and add any issues you may find. Thanks.

                                                        July 30, 2005

The Theoretical and Computational 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 2.6b1 has several advantages over NAMD 2.5:

- Ports to Itanium, Altix, and Opteron/Athlon64/EMT64.

- Improved serial performance on POWER and PowerPC.

- Adaptive biasing force free energy calculations.

- Tcl-based boundary potentials.

- Reduced memory usage for unusual simulations.

- Support for OPLS force field.

NAMD is available from

For your convenience, NAMD has been ported to and will be installed
on the machines at the NSF-sponsored national supercomputing centers.
If you are planning substantial simulation work of an academic nature
you should apply for these resources. Benchmarks for your proposal
are available at

The Theoretical and Computational 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

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