This is the second NAMD release this week, and fixes a couple of bugs in
2.5b2. I'm planning to have 2.5 final out by the end of the month (when
NCSA yanks the Origin 2000s away), so please give this a good thrashing.

NAMD users, please note the new NamdTroubleshooting page on the NAMD Wiki:

People reading this on VMD-L, please also note the existence of NAMD-L.

                                                  September 19, 2003

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 2.5b3 has several advantages over NAMD 2.4:

- Improved parallel scaling and serial performance.

- Trajectory reading and interaction energy analysis.

- Improved constant pressure simulation and coordinate wrapping.

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.

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