RogueWave (formerly Acumem) ThreadSpotter analyses the application on a binary level (your optimized code compiled with debugging symbols, aka {{{-O2 -g}}}), finding occurrences of inefficient memory access patterns, such as cache usage and cache-effects due to multiple threads. The strength of the tool is in the reporting of problematic source code, giving hints in the code, proposing changes and offering information, how the change may affect cache usage.
