Verify CUDA Installation

The following verification steps only apply to the cuda (full) installations and require nodes with physical NVIDIA GPU hardware.

Verify driver version by looking at: /proc/driver/nvidia/version:
```
cat /proc/driver/nvidia/version
```
Verify the CUDA Toolkit version
```
nvcc -V
```
Verify running CUDA GPU jobs by compiling the samples and executing the deviceQuery or bandwidthTest programs.
- Compile the samples:
```
git clone https://github.com/NVIDIA/cuda-samples.git
cd cuda-samples/Samples/1_Utilities/deviceQuery
make
```
- Run the deviceQuery sample:
```
./deviceQuery
```
  A successful run will end with Result = PASS.
- Run the bandwidthTest sample:
```
cd ../bandwidthTest
make
./bandwidthTest
```
  A successful run will end with Result = PASS.
NOTE: The CUDA Samples are not meant for performance measurements. Results may vary when GPU Boost is enabled.
