[gmx-users] Benchmarks

I've been testing my compilation of GROMACS to the published benchmarks on
the GROMACS website.  according to the data on the web, Villin finishes on
an 1.25 Ghz G4 machine with a time of 2048 seconds.

My powerbook finishes Villin (0.0002 ns timestep, 5000 steps) in roughly
700 seconds,

              NODE (s)   Real (s)      (%)
       Time:    701.240    715.000     98.1
               (Mnbf/s)   (MFlops) (ps/NODE hour) (NODE hour/ns)
Performance:      6.758    211.844     51.338     19.479
Finished mdrun on node 0 Tue Jun  7 11:56:05 2005

Am I to believe that my 867 MHz is 10-20x faster than an Apple G5
compiling Xlc?

Do I understand correctly that the columns on the serial benchmark page
are execution times where a lower number is better?  I used the files
available on the benchmarks portion of gromacs.org and attach my log file
from the run to this email.
