Hi everyone,

Here is the result of the mdrun which was performed on 16cpus. I am not
clear about it, was it due to using MPI reason? or some other reasons.

Writing final coordinates.

 Average load imbalance: 1500.0 %
 Part of the total run time spent waiting due to load imbalance: 187.5 %
 Steps where the load balancing was limited by -rdd, -rcon and/or -dds:
X 0 % Y 0 %

NOTE: 187.5 % performance was lost due to load imbalance
      in the domain decomposition.

        Parallel run - timing based on wallclock.

               NODE (s)   Real (s)      (%)
       Time:  52292.000  52292.000    100.0
               (Mnbf/s)   (GFlops)   (ns/day)  (hour/ns)
Performance:    523.244     19.720     16.523      1.453

Thanks and regards,


P.S I used the ngmcheck found it's okay, later analysis shown
