Hi,
What do you mean by exactly the same? MD is chaotic, and unless you run
mdrun in its reproducible mode, you will not get reproducibility of a
trajectory. gmxcheck may help you discover what you have actually got.
And you might want to upgrade such a prehistoric version of GROMACS ;-)

Dear all,
Sorry to interrupt.
I encountered a problem while using Gromacs 4.5.3 with mpi to simulate
ionic liquid constrained between two constant charged electrodes. However
when I use 1 core and 32 cores to run same simulation (with same .tpr
file), the charge density distribution of the first 3000 steps are exactly
the same, however later, in about 1 steps, the charge density
distribution of 32 cores and 1 core become different.
The compiling environment is: 1) gcc/4.7.22) openmpi/1.6.43)
fftw/3.3.4(double precision).
I am quite confused about it and wonder if anyone else has encountered the
same problem.
Best Regards,
Fei
