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
