WebOpenMP1is the result of a large agreement between hardware vendors and compiler developers and is considered to be an”industry standard”: it speciﬁes a set of compiler directives, library routines, and environment variables that can be used to specify shared- memory parallelism in Fortran and C/C++ programs. http://bebop.cs.berkeley.edu/bootcamp2014/omp-exercises.pdf

WebOpenMP Is: An Application Program Interface (API) that may be used to explicitly direct multi-threaded, shared memory parallelism Comprised of three primary API components: Compiler Directives Runtime Library Routines Environment Variables An abbreviation for: Short version: Open Multi-Processing WebThe flag also arranges for automatic linking of the OpenMP runtime library (Chapter 2 [Runtime Library Routines], page 5). A complete description of all OpenMP directives accepted may be found in the OpenMP Application Program Interface manual, version 4.0.
