* Explicit dispatch can be useful in avoiding the introduction of data copies into containers such

* The following code snippet demonstrates how to use \p thrust::omp::par to explicitly dispatch an
* invocation of \p thrust::for_each to the OpenMP backend system:
*
* \code
* #include <thrust/for_each.h>
* #include <thrust/system/omp/execution_policy.h>
* #include <cstdio>
*
* struct printf_functor
* {
* __host__ __device__
* void operator()(int x)
* {
* printf("%d\n", x);
* }
* };
* ...
* int vec[3];
* vec[0] = 0; vec[1] = 1; vec[2] = 2;
*
* thrust::for_each(thrust::omp::par, vec.begin(), vec.end(), printf_functor());
*
* // 0 1 2 is printed to standard output in some unspecified order
* \endcode
