OpenMP

The OpenMP Application Program Interface (API) supports multi-platform shared memory multiprocessing programming for in C/C++ and Fortran on many architectures, including Unix platforms and Windows platforms.

Jointly defined by a group of major computer hardware and software vendors, OpenMP is a portable, scalable model that gives programmers a simple and flexible interface for developing parallel applications for platforms ranging from the desktop to the supercomputer.

Often a so-called hybrid-model parallel programming, using both OpenMP and MPI (Message Passing Interface), is used for programming computer clusters.
