The Profile-Guided Optimization (PGO) Sample - Fluid Animate

Fluid animate is one of a class of algorithms for calculating fluid flow. There is one implementation using Intel® Cilk™ Plus technology. This sample uses the same serial implementation to demonstrate the use of Intel Profile Guided Optimization (PGO) without any code change.The PGO of Intel® C++ Compiler improves application performance by reorganizing code layout to reduce instruction-cache problems and branch mispredictions. With the collected application runtime information Intel C++ Compiler is able to be more selective and specific in optimizing the application. This may also help with application size introduced by aggressive inlining. You can find more in-depth explanation in this article Guide to Profile-guided Optimization of Computational Fluid Dynamics with Intel® Compiler.
