Each thread generates one number of the array and saves this in a temporary threadprivate variable. In a second parallelised region the test controls, that the temporary variable contains still the former value by comparing it with the one in the array.</ompts:testdescription> -<ompts:ompversion>2.0</ompts:ompversion> -<ompts:directive>omp threadprivate</ompts:directive> -<ompts:dependences>omp critical,omp_set_dynamic,omp_get_num_threads</ompts:dependences> -<ompts:testcode> -/* - * Threadprivate is tested in 2 ways: - * 1.
