Hi everyone,
I have to run some programs remotely in a cluster.
The problem is the following, the programs run for two or three days (they are really heavy). I connect to the cluster and run the programs using terminal.
The program runs properly, but if I close the terminal the program stops running, and if I disconnect from the network the program give me error.
Is there any way that I can run the program and I can disconnect or close the terminal and the program keep running?
Any suggestion will be greatly appreciated. Thank you very much!

Two command line programs that are useful (and are doing similar things) for this are 'screen', and 'tmux' (on unix, linux, mac, probably windows using ubuntu). I always use one of these when I connect up to a server, and start a computation running.
Best,
Mike

In addition to what Mike has suggested, I would like to add:
If you are over an unstable network or keep switching between networks, then use mosh, instead of ssh. You can start the mosh connection in a screen/byobu/tmux terminal.
For more details on mosh:
Hope this helps.

Hi,
I am not familiar with screen and/or tmux, so let me add a question. Is there an easy way to execute an .m2 file and ask the terminal to give me a warning whenever the process stops, e.g., if M2 runs out of memory or the file hits the quit() command? This way I don't have to periodically check it.
I managed to teach M2 to send me a push notification on my smartphone if some conditions are met, but if M2 itself stops then I did not find a way to do that. I admit I am not at all an expert with terminals.
Also, thanks for the screen/tmux suggestion! I have always been using the nohup command, which lets you run an .m2 file without a terminal showing the output. But then you have to prepare the .m2 file in order for it to save the output in some separate output file, so I realise it's not the best solution.
Best,
Fabio

Hi,
If mail is properly configured on the machine you could send yourself an e-mail when M2 exits. Just put the M2 command next to something like
mail -a /macaulay2/output/file/to/attach.out -s "Put down your cocktail, M2 is done!" m2u...@gmail.com < /dev/null
which will send you an empty text e-mail with the given attachment and subject to m2u...@mail.com.
There are also services which push notifications to your smartphone.
A cool app is https://pushover.net which you can trigger by
sending a message to their server. So this should work from any
machine that's connected to the Internet and can run curl or python.
Cheers,
Thomas
