The posted code is older and there is a concern for future support. There is no specific need although customers do like the idea of offloading some processing on a GPU which has software level compile times (as opposed to the FPGA).

I need this right now. Basically, I need a low latency path between the GPU and the FPGA that doesn't bother the CPU. This also gives you more determinism and saves you CPU resources.
