Profiling C++ multi-threaded applications

Question

Have you used any profiling tool like Intel Vtune analyzer?

What are your recommendations for a C++ multi threaded application on Linux and windows? I am primarily

Answer 1

VTune give you a lot of details on what the processor is doing and sometimes I find it hard to see the wood for the trees. VTune will not report on memory leaks. You'll need purify plus for that, or if you can run on a Linux box valgrind is good for memory leaks at a great price.

VTune shows two views, one is useful the tabular one, the other I think is just for sales men to impress people with but not that useful.

For quick and cheap option I'd go with valgrind. Valgrind also has a cache grind part to it but i've not used it, but suspect its very good also.
