The Fortran 95 compiler recognizes the OpenMP Fortran shared memory multiprocessing API as the preferred parallel programming model. The API is specified by the OpenMP Architecture Review Board (http://www.openmp.org).
You must compile with the command-line option -xopenmp, to enable OpenMP directives. (see 3.4.155 –xopenmp[={parallel|noopt|none}].)
For more information about the OpenMP directives accepted by f95, see the OpenMP API User’s Guide.
