Today, basically any computer on the market is a multi-core machine and for programs focusing on performance, we may have to focus on these multi-core CPUs and use concurrency in our programming models. OpenMP is the standard for shared-memory parallelism on multi-core CPUs. Existing programs often do not need to be radically modified or rewritten in order to benefit from OpenMP parallelization. Once the performance-critical sections in the code are identified...
