I am trying to reset the GPU of my Azure virtual machine (NVIDIA GPU Cloud Image running on Standard NV6 running Ubuntu 16.04.1) to get reproducible results on a deep learning algorithm. I found this NVIDIA help page, which explains that I cannot reset individual GPUs of a DGX-1 server:
In the case of the DGX-1 and DGX-1V platforms, individual GPU's can not be reset because they are linked via nvlink, so all the GPU's have to be reset simultaneously.
How can I find if the GPU on my Azure machine belongs to a DGX-1 server?
You should be able to query the OS to tell you what device you have. You didn't list he OS in your question to I will make the assumption it's Ubuntu. Here are a couple commands you could try.
GPU info on the N-Series can be found here: https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sizes-gpu
