While working on the implementation of the MPI version of the STREAM benchmark, I realized that there were some subtleties in timing that could easily lead to inaccurate and/or misleading results. If the clocks are synchronized, then all I need is: tstart = min(t1(k)), k=1.numranks numranks tstop = max(t2(k)), k=1.numranks.
