OpenMP (Open Multi-Processing) is an High level API for parallel programming in C, C++, and Fortran. It’s a widely-used, open-standard, and platform-independent library that allows developers to write parallel code that can run on multiple CPU cores, reducing the overall execution time of a program. OpenMP does the heavy lifting in several areas: Thread Management: OpenMP automatically manages thread creation, synchronization, and termination, freeing the developer from the complexity of thread management.
