NAMD 2.8b3 released

Hi all,

NAMD 2.8b3 is now available for download. This beta release fixes several
minor issues with 2.8b2 and uses a modified Charm++ that should eliminate
all "interrupted system call" errors.

We are hoping to ship a final 2.8 release next week, so please test 2.8b3
soon to help catch any remaining issues. Thank you as always for your
support of NAMD development.


(The only think new below is the date and version number.)

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 2.8b3 has many advantages over NAMD 2.7, among these are:

- Generalized Born implicit solvent model

- Accelerated molecular dynamics method

- MARTINI residue-based coarse-grain forcefield

- Non-uniform grids in grid forces

- Symmetry and domain restraints

- Collective variables module improvements

- Force output and trajectory files

- Shared-memory single-node and multiple-node builds

- Measurement-based grain-size adjustment in load balancer

- Experimental memory-optimized version with parallel I/O

- Microsoft Windows HPC Server port and released binaries

- Support for NBFIX parameters in CUDA builds

- Enhanced performance and scalability

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.
