I am following this tutorial https://docs.microsoft.com/en-us/azure/batch/tutorial-parallel-python on how to use Azure Batch API.
It is not clear from that article however what happens to the nodes in the pool after the batch run is complete.
The reason I care is that the nodes I will be using will need extensive setup before the batch begins. Is it possible to have the VMs retain that setup between runs so as to save the bandwidth and time required for setup?
And also, what if that setup requires a restart (after installing GPU drivers for instance), would that be possible to do before the cluster is used?
