This document specifies a collection of compiler directives, library functions, and

environment variables that can be used to specify shared-memory parallelism in C

and C++ programs. The functionality described in this document is collectively

known as the OpenMP C/C++ Application Program Interface (API). The goal of this

specification is to provide a model for parallel programming that allows a program

to be portable across shared-memory architectures from different vendors. The

OpenMP C/C++ API will be supported by compilers from numerous vendors.
