GPUs : 2 Nos - Tesla K80
Tensorflow-gpu - 1.15
During Training of model, I am seeing one GPU memory allocated but GPU Utilisation most of the time shows 0%, only few seconds it shows 100%, then again shows 0%. It is reflecting in epoch duration that it takes long time to training, that means one GPU is not utilised only memory allocated. Whereas other GPU is always 100% utilisation.
Please refer below screenshot. ProcessId is also shows for both GPU and memory of both GPU are allocated
What is the issue here? Why GPU memory used but GPU Util ?
