9.4 OpenMP Modules OMP_LIB and OMP_LIB_KINDS ¶

Standard:

OpenMP Application Program Interface v4.5, OpenMP Application Program Interface v5.0 (partially supported) and OpenMP Application Program Interface v5.1 (partially supported).

The OpenMP Fortran runtime library routines are provided both in a form of two Fortran modules, named OMP_LIB and OMP_LIB_KINDS, and in a form of a Fortran include file named omp_lib.h. The procedures provided by OMP_LIB can be found in the Introduction in GNU Offloading and Multi Processing Runtime Library manual, the named constants defined in the modules are listed below.

For details refer to the actual OpenMP Application Program Interface v4.5 and OpenMP Application Program Interface v5.0.

OMP_LIB_KINDS provides the following scalar default-integer named constants:

omp_allocator_handle_kind

omp_alloctrait_key_kind

omp_alloctrait_val_kind

omp_depend_kind

omp_lock_kind

omp_lock_hint_kind

omp_nest_lock_kind

omp_pause_resource_kind

omp_memspace_handle_kind

omp_proc_bind_kind

omp_sched_kind

omp_sync_hint_kind

OMP_LIB provides the scalar default-integer named constant openmp_version with a value of the form yyyymm, where yyyy is the year and mm the month of the OpenMP version; for OpenMP v4.5 the value is 201511.
