I recently installed the Nvidia graphics driver and CUDA on my Ubuntu 15.10 and Ubuntu 16.04 machines (with GTX 970 and GTX 970M respectively), both of which have x86_64 architecture. Much of the installation was done simply with apt-get, and the entire process went rather smoothly.
I'm now trying to install the same thing on a POWER8 ppc64el architecture server with Ubuntu 14.04 server edition installed. The server is equipped with Nvidia Tesla M2090 GPU.
However, the "standard" Ubuntu repositories (main, restricted, universe, multiverse) seem to not have Nvidia drivers nor CUDA, I couldn't install with apt-get as I did before. I tried downloading the Debian files from Nvidia website for ppc64el-based Ubuntu 14.04 (both graphics driver and CUDA), but the installation didn't quite go through. 
Does anyone have experiences installing CUDA on a ppc64el-based Ubuntu server?
Thanks a lot.
