Create a GPU-based block tutorial.

Dear GNU Radio,

Currently I am trying to create a GPU-based multiply conjugate block in GNU Radio. The purpose is the same as the regular GNU Radio multiply conjugate block, but I want to optimize the process by doing it in GPU cores. Previously, I was thinking to follow this tutorial to make it.

https://wiki.gnuradio.org/index.php?title=Creating_C%2B%2B_OOT_with_gr-modtool

Creating C++ OOT with gr-modtool - GNU Radio This tutorial describes how to create a custom C++ block and use it in a flowgraph: Create a new C++ block using gr_modtool; Modify the C++ .h and .cc code so the block will function wiki.gnuradio.org

However, I believe that tutorial is meant to develop a CPU-based GNU Radio block. I am trying to dig the internet but could not find any clear tutorial how to develop GPU-based GNU Radio block. Could you help and enlighten with regards to the procedure of developing GPU-based GNU Radio block?

Thank you in advance.

Best regards,
