Hi All,
I have used fora number of years Gimpels Flex-E-Lint LINT tool and
recently I have looked around for profilers. I use the Intel
Compilers and I know they have some treading tools too..
Can the Saturn Profiler be used for any application or is it
primarily used for hardware type applications? Where does
Instruments fit in? Gimpel came out with a new version of Flex-E-
Lint a bit ago, wondering if it is worth the upgrading..
I have played with ValGrind on Linux, but there is not an OS X
version available.
What are people using for performance, etc? Any straight C++ tools,
cross-platform capable?

The main tools for profiling on OS X are Instruments and Shark.
Instruments provides a wide breadth of profiling types and provides a
good overall analysis of a program. Shark has fewer profiling types,
but provides in-depth microarchitectural knowledge as well as
multithreading/OS interaction visualization.
Basically, look at what Instruments offers and look over the Shark
manual or WWDC sessions. Use the one that you like better and covers
the areas you specifically need.
