[gmx-users] Gromacs-3.3 released

[Erik Lindahl]

Hi,

We're happy to announce that Gromacs 3.3 is now officially released.

There are a bunch of new features that will hopefully be useful. A  
more or less complete revision list is available online, but just to  
mention a few highlights:

* Assembly loops for x86-64, both single-and double precision.  
(retuned from the first betas, works on EM64t too)
* Assembly loops for ia64, both single and double precision.
* TIP4P-specific optimization in all assembly loops, using the  
"normal" atom order.
* PME scales better
* Support for FFTW2, FFTW3, Intel MKL, and built-in FFTPACK fourier  
transforms
* PME is slightly faster, and scales better
* Free energy support in PME
* Replica exchange
* Much faster normal mode calculation, which works for huge systems too.
* Random access in XTC trajectories
* QM/MM support

You can find the source tarball at the website http:// 
www.gromacs.org , and also binary packages for Linux/i386, Linux/ 
x86_64, Linux/ia64, Linux/ppc64, and Mac OS X.

Have fun, and report bugs with the new tracker http:// 
bugzilla.gromacs.org !


Erik
