CUDA on K2 passthrough
We have the following setup - XenServer 7.1 on Dell R720 - XenDesktop 7.7 - Grid K2 card configured in passthrough, Driver Version: 367.106 - VM running Windows 10 VM is accessed through Citrix using HDX 3D Pro We are trying to use the VDI for video editing using Premiere Pro and AfterEffects. The GPU is recognized in Windows 10 and OpenCL and DirectX are working correctly. For the use of Premiere Pro we need CUDA to force the rendering on the GPU instead of using the CPU to render videos. Is this supported using the NVIDIA GRID K2 card?

Hi Yes, this will work, Passthrough is your only recommended option with Kepler for CUDA use. Regards Ben

With the driver version i found on the Nvidia website CUDA is not available. http://www.nvidia.co.uk/download/driverResults.aspx/119900/en-uk Do i need to install or configure any other components to get this to work?

What are you using to validate whether CUDA is active or not? I'm not aware of any driver changes to remove CUDA from Passthrough, it was available on earlier driver releases with earlier versions of XenServer.

I'm using GPU-Z to check the features of the GPU In Premiere Pro and AfterEffects the card is not recognized and the rendering options are stuck on Software Only

GPU-z is not the best tool for that. There were previous reports of it not detecting CUDA despite it being active. Try using this: http://cuda-z.sourceforge.net/
