Let me get this straight: you're trying to performance tune some application using TBB or you're trying to performance tune TBB itself? Our developers already do quite a bit of performance tuning on the library itself. If you're intent on tuning TBB, you might start by using a newer version: 2.1 is more than a year old; 2.2 was released last summer and we're on the verge of releasing 3.0.
Regarding help using Caliper, you might have more success posting your query at an HP forum or website. There are lots of people on this site who can tell you about VTune analyzer and about Intel Parallel Amplifier, but probably only a few who have any experience with Caliper.
