Developers looking to optimize the performance of their C++ code should discover compiler optimizations: a set of very effective C++ flags that improve the code performance without much effort. The only prerequisite is that you know what you're doing. Explore flags suitable for Intel C++ compilers such as -fno-alias, -xHost, -xCORE-AVX512, IPO, etc, with a hands-on showdown on a Jacobi iteration C++ code.
