I'm trying to run a couple of remote servers with ipcontroller and ipengine. So I start a single process with ipcontroller on "master" node, which I will be running ipython notebook on at the end.
Running ipengine on remote hosts goes smoothly thanks to lots of available tutorials. After running ipenigne for each host based on their number of CPUs, I use disown -a to avoid closing running ipengine in the background. However for some reason they do not keep running after closing the SSH session. I have even used nohup command but again a similar behaviour. I would appreciate any input on this issue.
Use screen. Its should be installed on any linux distribution.
It will keep the session running after you disconnecting the ssh.
Here is a tutorial I googled for you:
