What is OpenMP program?
OpenMP is a library for parallel programming in the SMP (symmetric multi-processors, or shared-memory processors) model. When programming with OpenMP, all threads share memory and data. OpenMP supports C, C++ and Fortran. The OpenMP functions are included in a header file called omp.
How do I enable OpenMP?

What is OpenMP and MPI?
• OpenMP (shared memory) – Parallel programming on a single node. • MPI (distributed memory) – Parallel computing running on multiple nodes.
What is OpenMP directive?
OpenMP is a set of compiler directives as well as an API for programs written in C, C++, or FORTRAN that provides support for parallel programming in shared-memory environments. OpenMP identifies parallel regions as blocks of code that may run in parallel.
