 *  \p thrust::system::cpp::par is the parallel execution policy associated with Thrust's standard

 *
 *  Instead of relying on implicit algorithm dispatch through iterator system tags, users may
 *  directly target Thrust's C++ backend system by providing \p thrust::cpp::par as an algorithm
 *  parameter.
 *
 *  Explicit dispatch can be useful in avoiding the introduction of data copies into containers such
 *  as \p thrust::cpp::vector.
 *
 *  The type of \p thrust::cpp::par is implementation-defined.
 *
 *  The following code snippet demonstrates how to use \p thrust::cpp::par to explicitly dispatch an
 *  invocation of \p thrust::for_each to the standard C++ backend system:
 *
 *  \code
 *  #include <thrust/for_each.h>
 *  #include <thrust/system/cpp/execution_policy.h>
 *  #include <cstdio>
 *
 *  struct printf_functor
 *  {
 *    __host__ __device__
 *    void operator()(int x)
 *    {
 *      printf("%d\n");
 *    }
 *  };
 *  ...
 *  int vec[3];
 *  vec[0] = 0; vec[1] = 1; vec[2] = 2;
 *
 *  thrust::for_each(thrust::cpp::par, vec.begin(), vec.end(), printf_functor());
 *
 *  // 0 1 2 is printed to standard output in some unspecified order
 *  \endcode
 */
