I was wondering if it is somehow possible to start a parallel calculation (where each part that is run in parallel takes about an hour) on remote subkernels, then disconnect the Internet connection, and still get the results from the remote subkernels after reconnecting?
The usual behaviour that I witnessed was that Mathematica just notices that the remote subkernels are gone and requeues their calculations to local subkernels.
I guess the remote subkernels would have to be started with
nohup or something like that, and I have to find a way to tell Mathematica to wait for longer before requeueing, but I have no idea how to do that or if it is even possible.
After some more searching I found the following relevant questions, so I link them here for anyone who wants to solve a similar problem:
How can I connect to a remote machine? (the title sounds very generic, but the answer is kind of what I want... if it still works in Mathematica 11)
