[TF CUDA Optimization Options] All the tensorflow with cuda optimization you need! Will speedup at least 1.3 times in Volta and Turing architecture! Only works with the tensorflow gpu version build from source with cuda/cudnn support, or use the docker image from nvidia gpu cloud <ngc.nvidia.com>. #tensorflow #cuda
# mainly from:
# 1. https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#env-vars
# 2. https://github.com/NVIDIA/DeepLearningExamples/issues/57
# 3. https://docs.nvidia.com/deeplearning/frameworks/tensorflow-user-guide/index.html#variablesaddtf
