Hi Stephane,
I installed libpfm4 and played a little bit arround with the example syst
and task.
I want to run a repeating workload for several hours and grab useful
performance data on Intel Nehalem.
Can you recommend a set of performance counter which capture the most
significant information? I just want to have a good starting point for
further research ...
Regards, edy
