[gmx-users] pme grid with gpu

[Mahmood Naderan]

Hi,
When I run mdrun with "-nb gpu", I see the following output


starting mdrun 'Protein'
20000 steps,     40.0 ps.
step  200: timed with pme grid 64 80 60, coulomb cutoff 1.000: 3340.0 M-cycles
step  400: timed with pme grid 60 72 56, coulomb cutoff 1.075: 3742.2 M-cycles
step  600: timed with pme grid 60 80 56, coulomb cutoff 1.062: 3725.5 M-cycles
step  800: timed with pme grid 60 80 60, coulomb cutoff 1.037: 3667.2 M-cycles
step 1000: timed with pme grid 64 80 60, coulomb cutoff 1.000: 3564.0 M-cycles
              optimal pme grid 64 80 60, coulomb cutoff 1.000
step 9400, remaining wall clock time:   104 s          



The last line is updated and the new line replaces the previous (last) line. I wonder why the first 100 steps are shown in separate lines ("\n"). That is not happening with "-nb cpu". 



Any thought?

Regards,
Mahmood
