Hi guys Afraid I won't be able to make the next meeting..again!..but id also be interested in this. On a slightly related topic, I'm working with someone at the uni for plating with pyCUDA and pyOpenCl so hope to have some results on GPU/XeonPhi and FPGA soon. As NVIDIA have given us some free Jetsons I'm keen for others to offer some thoughts on using these frameworks. Just a thought for a future topic and i can bring a Jetson in. Cheers, hope all well Dave
