[gmx-users] Load imbalancing

[Bratin Kumar Das]

Dear all,
            I am running REMD simulation with 65 replicas. When the
simulation is running , I checked the .log file for every replica. In some
replicas I am getting more than 10% load imbalancing. How to solve that. If
I use -ntmpi and -ntomp option ..mdrun is throwing a fatal error

 Fatal error:
Setting the number of thread-MPI ranks is only supported with thread-MPI and
GROMACS was compiled without thread-MPI

In the document (
http://www.gromacs.org/Documentation/Acceleration_and_parallelization)...it
is mentioned that -ntmpi can not be used in multi-simulation runs.....
So how i can avoid load imbalancing in remd simulations...
