Hi Eduemon, You may want to take a look at gr-cuda which takes advantage of the "custom buffers" feature of GNU Radio introduced in GR 3.10:
https://github.com/gnuradio/gr-cuda This is a bare OOT but would be a good place to start adding blocks in or fork off into your own OOT. There is a multiply_const block in there that is GPU accelerated with CUDA.
