Thanks, effectively tmux is a good solution.

I don't think this is a Slurm issue, you just need to make sure you're running 
each of the srun's in a different terminal, whether that be an ssh session, an 
xterm or using screen or tmux to multiplex terminals on a single session.

All the best,

no I am using the option --unbuffered to watch the output in a terminal
window.

Re: [slurm-users] spawning a new terminal for each srun

[Renfro, Michael]

Is this output file being written to a central file server that can be accessed 
from your submit host? If so, start another ssh session from your local 
computer to the submit host.

Is the output file being written to a location only accessible from the compute 
node running your job? You might be able to ssh from the submit host to the 
compute node (or maybe from your local computer to the compute node).

Sorry, I am only trying to look at the output from my program, it is a
batch computation program that outputs some text line.

srun --pty does not open another window.

ps: I would like to do it from a bash script. I have attepted to use
gnome-terminal to spawn a new window for each srun line but I get an
gnome protocol error, so I am searching another method.

Re: [slurm-users] spawning a new terminal for each srun

[Brian Andrus]

I believe you are referring to an interactive terminal window.

You can do that with srun --pty bash

Windows themselves are not handled by slurm at all. To have multiple 
windows is a function of your workstation. You would need multiple 
connections to the cluster (eg: multiple ssh windows with multiple ssh 
connections)


In each ssh session, execute 'srun --pty' and you will have an 
interactive session on the cluster. You would, of course, need any other 
options for partitions, timelimit, etc.



That being said, this is usually NOT the way to approach a solution via 
a cluster. Clusters are meant to be something that does all the work for 
you while you are away (hence the batch concept). You likely want to 
look at getting your code to run without human interference and send it 
off to do so.

multiple srun statements with --pty options will spawn multiple
terminals. Just like running bash multiple times, if you do it within
the same terminal it will create a terminal within a terminal.

So, I would ask: what are you trying to do and we may be able to advise
the best way to accomplish it.

I would like to open a new terminal window for each srun job so that
each job has its own terminal window.

Re: [slurm-users] spawning a new terminal for each srun

[Brian Andrus]

A little more details of what you are trying to do would help.

multiple srun statements with --pty options will spawn multiple 
terminals. Just like running bash multiple times, if you do it within 
the same terminal it will create a terminal within a terminal.


So, I would ask: what are you trying to do and we may be able to advise 
the best way to accomplish it.
