There is a zombie process on cookie's GPU. You can take a look with nvidia-smi -a 
Utilization is 99%, meaning no work can be done on the GPU until it is free. Which will be never until cookie is rebooted. nvidia-smi for sdk 4.0 does not have the capability of resetting the GPU on the fly, however the sdk 4.1 version will have it. Until then... 

Not sure when is a good time for a reboot. I know Krishna has a pbound job running, so I'd like to get a consensus of cookie users. 

Let me know. Thanks.
