WebBecause OpenMP is built into a compiler, no external libraries need to be installed in order to compile this code. These tutorials provide basic instructions on utilizing OpenMP on both the GNU Fortran Compiler and the Intel Fortran Compiler. This guide assumes you have basic knowledge of the command line and the Fortran Language. WebOpenMP represents a collection of compiler directives, library routines and environment variables meant for parallel programming in shared-memory machines.
