Hi everyone,
Kindly help to accelerate this mdrun process as you could see that its
showing following timing for the command along with provided gmx -version.

  gmx mdrun -deffnm md_0_1 -ntmpi 5 -ntomp 6 -pin on -v

starting mdrun 'protein in water'
5000000 steps,  10000.0 ps.
step 17000, will finish Wed Jul  3 22:01:39 2019imb F  2% imb F  5%
