BTW, recently Nikolay Sidelnikov wrote the draft version of the doc as
a standalone page. Interested parties can look into HARMONY-2865
Armand, you may find it extremely useful :)
Nadya, Sveta, could you, please, look into the doc?..
Nice - it would nice also if Nikolay had the time, to augment that
with an example output of the .stat file, so people using this for
the first time can feel comfortable that they got the right thing,
and maybe some notes on how to read the .stat file.

1. You can get any stylesheet editor (like Excel), open iprof

gnuplot :)
2. The disadvantage of iprof is that it counts blocks, insts and
helpers
calls and does not count time spent in helpers and blocks. You
still need
VTune to get this info.
1 more disadvantage: counters are not synchronized resulting in
somewhat inaccurate data for multithreaded apps
