environment in the place list.
* omp_get_place_num_procs - returns the number of processors available to the
execution environment in the specified place.
* omp_get_place_proc_ids - returns the numerical identifiers of the processors
available to the execution environment in the specified place.
Typically called inside parallel region:
* omp_get_place_num - returns the place number of the place to which the
encountering thread is bound.
* omp_get_partition_num_places - returns the number of places in the place
partition of the innermost implicit task.
* omp_get_partition_place_nums - returns the list of place numbers
corresponding to the places in the place-var ICV of the innermost
implicit task.
