[slurm-users] About x11 support

[Tina Friedrich]

I really don't want to start a flaming discussion on this - but I don't 
think it's an unusual situation. I have, in likewise roughtly 15 years 
of doing this, not ever worked anywhere where people didn't have a GUI 
to submit from. It's always been a case of 'Wand to use the cluster? 
We'll make your workstation a submit host.'

I think it's a pretty standard way of handling things it you are an 
institute that runs their own (maybe small) cluster, especially if the 
workstations are also managed machine.
