A wrapper script has been created to run X11 applications, called "idev" (interactive-development), or nicknamed "xrun". This has been installed into /usr/local/bin on login and compute nodes. To use it, do the following steps:
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:
a) If using the Putty SSH client on Windows, make sure that the X11 forwarding box is checked.
b) If using MacOS or Linux, connect using "ssh -Y"
3) Once on a Talapas login node, you have two options available:
1. type "xrun". You can pass many of the same arguments to xrun as you can to srun, e.g.:
$ xrun -N1 -n1 --time=02:00:00
2. use "srun" with the "--x11" option (available in the Slurm 17.11 module), e.g.:
$ srun -N1 -n1 --time=02:00:00 --x11 --pty bash -i
4) Launch your X11 application (e.g. type "xclock")
