So, I am *guessing* that the latest version of slurm is not compatible with
1804 from Centos. In other word, something has been added/fixed in the ssh
library which is now causing some mismatches.
It's not getting that far, you first need to fix the problem that causes this
error:
srun: error: Cannot forward to local display. Can only use X11 forwarding with
network displays.
as srun looks likes it's stopping for you there with the required --x11 flag.
This is not an error, Mahmood could fix. This is the same for me. It is,
because I can submit from my workstation directly to SLURM. So DISPLAY
ist set to ":0".
So it is a socket, which is prohibited by SLURM:
if (display[0] == ':') {
error("Cannot forward to local display. "
"Can only use X11 forwarding with network displays.");
exit(-1);
}
The 'fix' for Mahmood would be to ssh to another host and then submit
the X11 job.
Best
Marcus
