[gmx-users] energygrps and simulation run time

2010-07-27 Thread Amir Marcovitz
Hi,

Does the use of energy groups (energygrps) in the *.mdp file may cause some
slow down in the simulation running time?

Thanks,
Amir

Certainly not in the case of just a few groups.  If you have tons of energy 
terms to write, then it's possible that the disk I/O is causing some lag.  This 
will also depend on the frequency with which you're writing these terms.
