====GPUs====

There are 2 beefy GPUs installed for general development.


As of Jan 11, 2018 both host computers have the latest driver version 387.26 and CUDA 9.1 installed.

The NVIDIA samples are in ~/NVIDIA_CUDA-9.1_Samples and built with no errors from the source code.

The Titan Xp has 12GB RAM! But the GeForce GTX 690, although less capable, actually has 2 separate GPUs in one package.
