Hi all !
Thanks for this helpful article.
I have one question tho :
When I use the “srun” command : srun -n ./fluent-srun.sh, I do have a job running on slurm for some seconds. I also have the command line of fluent in my terminal, but after a few seconds, nothing happens (no GUI, the slurm job is cancelled) and I don’t have any error.
If I use the same fluent command without the srun : ./fluent-srun.sh, the fluent GUI appears. (exactly the same thing happens with star-CCM+).
I hope you can help me.
Thank you !
Regards,
Léo
Most likely there is an issue with your DISPLAY variable not being passed. In recent versions of Bright you can actually use your web-browser to access the cluster through Jupyter, and then you can schedule a kernel (e.g. BASH kernel) and start a VNC server on the node. Your web-browser will then show you the X11 window manager + any X11 applications you start. See https://www.youtube.com/watch?v=JWiRLx9M2R4&ab_channel=BrightComputing and in particular the part about VNC sessions.
