1. Install an X11 server on your desktop or laptop, e.g. "Xming" on Windows, or "XQuartz" on MacOS. 
2. SSH to one of the Talapas login nodes (talapas-login.uoregon.edu) with X11 forwarding enabled:
   1. If using the Putty SSH client on Windows, make sure that the X11 forwarding box is checked.
   2. If using MacOS or Linux, connect using ssh -Y
3. Once on a Talapas login node, you have two options available, xrun or srun.
   1. Using xrun, you can pass many of the same arguments to xrun as you can to srun.
   2. Using srun, use the --x11 flag (available in the Slurm 17.11 module)
4. Launch your X11 application, e.g. type xclock

xrun -N1 -n1 --time=02:00:00
