[gmx-developers] Monte Carlo Simulations

[André Assunção S. T. Ribeiro]

Hi,

Some time ago I sent an email saying that the CRA moves of Ulmschneider and Jorgensen had been implemented in 4.5.3. Since then we have used this code in combination with regular MD and the results seem promising. A paper reporting our earlier results has been recently published (DOI 10.1002/jcc.22925). The code is still based on 4.5.3, but I could put this into the latest development version, if that interests anyone.

Cheers,
Andre.

Hi, all-

MC is definitely an interest of mine, and I think I've already volunteered
to help organize more MC functionality on the core developer side.

Any MC functionality will be part of 5.0 going forward, and will not be in
any 4.0 version.  The most likely scenario (there's no settled plan yet) is
to have MC be the parent integrator, and have MD as essentially a
rejectionless MC variant; this will allow things like hybrid MD/MC, etc.
The integrator code is too complicated right now, and this will likely be
part of a larger effort to make the integrators simpler in 5.0.

Right now all the developers are concentrating very hard on getting 4.6 out
the door, so there is not much time to think about it new 5.0 features.  But
definitely ping me about this as soon as you hear about 4.6 being released,
and we'll start diving in.

The hard part is not WRITING the MC code, it's fitting it into the rest of
the code in a smooth way.

Best,
