As you know, OpenMP 4 contains vectorization pragmas (`pragma omp simd') which not perfectly suites for GPGPU. Another problem is how to create threads dynamically on GPGPU. As far as we understand it there're two possible solutions: 1. Use dynamic parallelism available in recent API (launch new kernel from target) 2. Estimate maximum thread number on host and start them all from host, making unused threads busy-waiting There's a paper which investigates both approaches [1], [2].
