Matlab Freezes when changing gpu using gpuDevice

For the past few days I've been struggling to get Matlab to work with my GPU. As soon as I switch to Tesla K80 GPU from GTX 970, Matlab freezes completely. I would have to force-shut it down. This happened after Windows 10 updated a few days ago. Everything was working fine before that.

I had Matlab 2015b, which worked until a few days ago. Now, I have Matlab 2016b, and the latest updates of GPU drivers. It still doesn't work.

Can someone help please?

What platform are you running on? Where is your K80 located? What is the output of nvidia-smi on the command line?

I encountered a similar issue. Issuing the command gpuDevice keeps Matlab freezing. The Task Manager shows Matlab is running. My system is Windows 10 on Asus Z270-A with i7-7700K 32GB ram, using Matlab 2015a and 2017a. I have an nvidia K40 located on the first slot of the pci-e. Display uses the GPU of i7-7700K.

My nvidia-smi listing is as follow:

_

P.S.: The Matlab can run the K40m okay if I switch the operating system to Ubuntu 16.06.
