10.4 OpenMP Modules OMP_LIB and OMP_LIB_KINDS

Standard:

OpenMP Application Program Interface v4.5

The OpenMP Fortran runtime library routines are provided both in a form of two Fortran 90 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 for the pause-related constants to the OpenMP 5.0 specification.

OMP_LIB_KINDS provides the following scalar default-integer named constants:

omp_lock_kind

omp_lock_hint_kind

omp_nest_lock_kind

omp_pause_resource_kind

omp_proc_bind_kind

omp_sched_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.

The following scalar integer named constants of the kind omp_sched_kind:

omp_sched_static

omp_sched_dynamic

omp_sched_guided

omp_sched_auto

And the following scalar integer named constants of the kind omp_proc_bind_kind:

omp_proc_bind_false

omp_proc_bind_true

omp_proc_bind_master

omp_proc_bind_close

omp_proc_bind_spread

The following scalar integer named constants are of the kind omp_lock_hint_kind:

omp_lock_hint_none

omp_lock_hint_uncontended

omp_lock_hint_contended

omp_lock_hint_nonspeculative

omp_lock_hint_speculative

And the following two scalar integer named constants are of the kind omp_pause_resource_kind:

omp_pause_soft

omp_pause_hard
