I use TAU
http://www.cs.uoregon.edu/research/tau/home.php
because, sadly, I found out that my g++-4.3.2
does not produce reliable results when profiling
OpenMP code. As I consider optimizing without
profiling an entirely meaningless business, I
had to look for a profiler, too.
You might find that TAU-2.18.2p2 is not very C++
friendly, though. I have submitted some patches
to the TAU developers, which are already in
their CVS, but are not available to the general
public. Give me a buzz on private e-mail, if
you need more info.
BTW, TAU is tremendously more fun when operated
on top of a PerfCtr-enhanced kernel. :-(=)
Thanks,
Chris
