Run gpuDeviceCount, initially the result is 3 (1 for NVS 315, 2 for K80) and the default gpu device is K80. But after some time, maybe 5 mins, the K80 disappear and cannot be used.
Our system:
Dell Workstation 7910
Xeon® CPU E5-2620 2.4GHz
Windows 7 64 bit operation system.
GPU card: NVS 315, K80
CUDA 7.5

It would be helpful if you provide more detail as to what you are doing in those five minutes and exactly what causes the K80 to disappear. If you run nvidia-smi on the command line (C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe) is the device still there?

Did you find a solution to this problem....?
I am experiencing the same kind of problem on the Tesla K80 I have two other versions of Matlab successfully running on two of the gpus of the K80 system (7/8 in total)....
But when I run gpuDeviceCount in a freshly opened version of Matlab ...I get an error... looking inside gpuDeviceCount at the error that parallel.gpu.GPUDevice.count gives,
i get:
parallel:gpu:device:UnknownCUDAError
An unexpected error occurred during CUDA execution. The CUDA error was:CUDA_ERROR_OUT_OF_MEMORY
