HOOMD 0.6.1 Released
With a lot of recent interest in HOOMD, we thought it pertinent to release an updated version with the performance and stability bugs fixed. The benchmarks page has been updated to reflect the performance of 0.6.1.
Changes since 0.6.0
- Compatibility improved with certain versions of Boost
- Numerous performance and stability improvements
- HOOMD should now compile on CUDA capable Mac OS X systems. We don't have such a system, so we cannot test this configuration
Major new features, such as the job scripting system are still on track for release in a few months with 0.7.0.

Progress update
We are making good progress toward HOOMD version 0.7. Major changes include a fix to the CUDA bug workaround that is present in 0.6.0. In the current development version, simulations are stable for runs longer than 150+ hours, with lj_liquid_bmark running at ~193 time steps per second on a Tesla C870.
Another major change is the inclusion of a simple scripting system for creating simulations. With the new scripting system, running simulations will be made much easier than in 0.6.0. For example, a simple Lennard-Jones liquid simulation will look something like this
# note: this is preliminary syntax, it may change in the final release
from hoomd_script import *
init.create_random(N=1000, phi_p=0.2, 'A')
integrate.nvt(T=1.2, tau=0.5, dt=0.005)
coeff = pair_coeff()
coeff.set(('A', 'A'), dict(epsilon=1.0, sigma=1.0))
lj = pair.lj(r_cut=3.0)
lj.pair_coeff(coeff)
run(1e6)
If this looks similar to LAMMPS scripts to you, that is no accident. HOOMD's scripting system has been designed to be that way so that LAMMPS users can use HOOMD with little or no learning curve.
It's hard to put an exact date on the release, but it should be coming within the next few months.

HOOMD at the APS March Meeting 2008
We were at the American Physical Society (APS) march meeting in New Orleans and displayed a poster on our work "Molecular Dynamics of Polymer Systems on Graphics Processing Units (GPUs)".

HOOMD 0.6.0 Released
HOOMD 0.6.0 is the first public release of HOOMD. It includes several benchmarks and demos to showcase the performance of the GPU. It is not intended for use with production simulations.
We are hard at work on the next release which will include an easy to use scripting system for setting up and running simulations

HOOMD source code now available
The source code for HOOMD is now available for download under a BSD-style license. It can be accessed through the subversion server http://svn2.assembla.com/svn/hoomd. An online source code browser is also available at the development page. For more information, see the documentation.
Any interested developers are welcome to download, browse and use the code. Users wishing to put HOOMD to work performing simulations should wait until HOOMD 0.6 is released, which will include executables to download.
