OpenMP parallelization directives are only recognized when compiling with -openmp. Details regarding OpenMP parallelization can be found in the OpenMP API User's Guide.
The Fortran compiler supports the OpenMP API for shared memory parallelism, Version 4.0. Legacy Sun and Cray parallelization directives are now deprecated and should not be used.
The Fortran compiler recognizes the OpenMP API for shared memory parallelism as the preferred parallel programming model. The API is specified by the OpenMP Architecture Review Board (http://www.openmp.orghttp://www.openmp.org).
You must compile with the command-line option -xopenmp, to enable OpenMP directives. (see –xopenmp[={parallel|noopt|none}].)
For more information about the OpenMP directives accepted by f95, see the OpenMP API User’s Guide.
