Effective optimization strategies on modern C++ compilers

Question

I\'m working on scientific code that is very performance-critical. An initial version of the code has been written and tested, and now, with profiler in hand, it\'s time to

Answer 1

If you are doing heavy floating point math you should consider using SSE to vectorize your computations if that maps well to your problem.

Google SSE intrinsics for more information about this.
