I am currently trying to run a script file on a 24 node cluster, which I have accessed through PuTTY. The script will probably take around 48 hours and is a series of 400 individual simulations. However if the SSH connection is interrupted for any reason (computer goes into sleep mode, require undocking my laptop and so internet connection switches from ethernet to wifi etc.) then the simulation stops, citing a ‘Fatal I/O error’.
I have tried using the ‘screen’ command and detaching the screen, I have also tried ‘nohup’. Both still terminate the simulation if the session is closed.
I think the problem is that even if I use the -nw option, every time a new simulation starts a job manager window pops up with the usual dialogue. I believe it is this window that Lumerical is trying to deliver to my computer screen when disconnected and providing the error. Is there any way to get around this?
EDIT: It’s preferable to not have the job manager screen pop up with each simulation run, is there any way to suppress this screen from appearing? (I suppose I could append all the simulations to a job list and then run that)
