hi,
I want to ask :
Can I get the timestamps at the beginning of the programs in sampling mode?
I can only get the timestamps of the smaples by  now.
 
following is the command I used :
pfmon --follow-all --smpl-outfile=equake_out --short-smpl-periods=1000000 --smpl-module=compact --overflow-block --with-header --reset-non-smpl-periods -e unhalted_core_cycles,instructions_retired -- ./equake < inp.in
 
 
thanks,
edward
