Hello, I'm testing X11 forwarding and it seems it runs *much* slower if I run it through Slurm as opposed to running it via ssh forwarding.
For example, running ANSYS via srun gives me extremely laggy, unusable output: login ~]$ env --unset LD_PRELOAD srun --pty --x11 bash node ~]$ unset SLURM_GTIDS node ~]$ module load ANSYS node ~]$ runwb2 ...but if I allocate node and ssh into it, output is considerably faster and interface is much more responsive: login ~]$ env --unset LD_PRELOAD salloc login ~]$ ssh -X node node ~]$ module load ANSYS node ~]$ runwb2 Is there any way to speed up or debug X11 forwarding via Slurm?
