[gmx-users] pairs types for decoupling

2007-04-03 Thread David Mobley
All, I'm using the CVS version of 3.3.1 from last week, and am trying to get the new pairs types Berk Hess has implemented to work for doing decoupling. There's an old e-mail here on the subject, which is all I've got to go by: http://www.gromacs.org/pipermail/gmx-developers/2006-March/001530.htm

Howdy, We are bringing a one rack (1024 node) IBM Blue Gene/L system online. I've been tasked with compiling Gromacs for the Blue Gene. We have the XL compilers installed (blrts_xlc / mpixlc, etc), so I'll be using those rather than GNU. Has anyone on here successfully cross compiled Gromac

[gmx-users] request for patch and test program from 'Speeding up Parallel GROMACS'

Hi I was happy to see the 'Speeding up Parallel GROMACS' paper. I'd like to try the GROMACS patch for better all-to-all, as well as the all-to-all test program referred to on the paper. I can't find it on the GROMACS site. We've got a Cisco 6500 and when I run tcpdump during MPI runs I see a h

Hi Gleb, Apparently I wasn't clear enough. g_rmsdist calculates the average distance for each pair of atoms over time and then calculates, for each frame, the deviations from the average distance for each pair of atoms. Per frame, these deviations are summed and the square root is taken. You're r

Hi Tsjerk, Thanks very much for the response. Just to make sure I understand correctly, g_rmsdist calculates an average interatom distance value for the reference structure. At a time t, a similar average interatom distance is calculated and the observed deviation is the difference between this

I have a question about simulating metal ions in aqueous solution at an infinite diluition: say I have a metal ion (such as Ca2+ or Mg2+) and about a thousand water molecules. I have to compensate the non zero charge of the system with negative ions? As I can understand the use of a reaction field
