How I can get total CPU time in VASP?
--- grep CPU time OUTCAR----

I wrote something in my submit a job script,

echo -n Start Date: >> datework
mpirun -hostfile mpd.hosts -ppn 8 vasp533 > out
echo -n End Date: >> datework

When I divided related processor and nodes number, I hadnt get same time? Where I am wrong?

Thanks
