That should work once the code is corrected. Can you use
MPI_Wtime()? (Not necessarily a big deal, but should be a portable
way of getting high-quality timings in MPI programs.) In what sense
does it not capture the complete time?

Does MPI_Wtime of OMPI 1.4.3/1.5.0 rely on high resolution clocks (for
Linux) or does still rely on gettimeofday() ? How would one request at
OMPI built time to let it use high resolution clocks?
thanks ...
