[Darshan-users] Darshan & EPCC benchio different behaviour

[Piero LANUCARA]

Dear all

I'm using Darshan to measure EPCC benchio benchmark 
(https://github.com/EPCCed/benchio) behaviour on a given x86 Tier1 machine.

running two benchio tests (MPI-IO and serial) a different behaviour appear

while Darhsan pdf log file is able to recover the estimated time and 
bandwidth in the MPI-IO case, the "serial" run is completely 
underestimated by Darshan (the time and bandwidth are less/greater than 
benchio output).

Suggestions are welcomed

thanks

Piero
