Andrew,

I confirm oprofile (0.96 on my fedora 14) works just fine (see below).

Do you recommend me to use the latest (git) version ? 0.96 is quite old
(2011)

Could you explain me a bit how to get sample counts corresponding to the
complete benchmark (few minutes long) ?
should I use the event argument to set the highest count (reset) value ?

By default, oprofile uses: CPU_CLK_UNHALTED:100000:0:1:1

opcontrol --event=CPU_CLK_UNHALTED:400000

What is the maximum value I can set  ?

[bourgesl at jmmc-laurent test]$ opreport -l -t 0.1 | grep pisces
CPU: Intel Westmere microarchitecture, speed 2800 MHz (estimated)
*Counted CPU_CLK_UNHALTED events (Clock cycles when not halted) with a unit
mask of 0x00 (No unit mask) count 100000
