My jealousy level has reached 72%. Not over the P100s, but POWER8. Anyone who knows me knows I'm a huge fucking PPC fan.

Anyway, obviously the Nvidia driver is installed, but it looks like you don't have an OpenCL ICD, or the linker can't find it. Not sure which distribution you're using (aside: make sure you're using a little endian distribution) or how you installed the driver, but it looks like you're missing some things. Also, this might be relevant (hints that the PPC Nvidia driver may be lacking libOpenCL.so): https://devtalk.nvidia.com/default/topic...on-power8/

I also simultaneously wonder if there's an OpenCL SDK or runtime environment for the POWER8 CPUs.
