Gaussian GUI

Back to Gaussian
When starting gv via a SLURM GUI Session the following steps must be taken:

• Set gv to use MESAGL instead of OpenGL via 'export USE_MESAGL=1'. See http://csc.cnsi.ucsb.edu/docs/gaussview for reference.

Load modules

module load gaussian gui

Start a GUI session

• Example: running Gaussview with 1 CPU, 8gb of memory, 4 hours of run time

gui start -e gv -c 1 -m 8 -t 4

• Note: Give the session from few seconds to a couple of minutes to start if the output is empty.

$ gui show

The output will look similar to the following e.g. with 1 active sessions and real passwords listed instead of 'REDACTED' in the example:

Current GUI sessions:
______________________________________________________________________________
#:  JobID    Application   Type  State       Reason
1: 51019979 gv            gui   RUNNING

Connection URLs:

Please copy a connection URL and paste it into a modern web browser's
location bar on your LOCAL computer located on campus or connected via OOD

Connect To GUI Session

• Attach to the job session in your local browser

Copy and paste a session URI into a modern browser (tested on Firefox and Chrome/Chromium) e.g.

https://gui3.rc.ufl.edu/13132/?password=REDACTED

As a result the browser tab becomes a 'desktop canvas' and the GUI program window should be visible and can be resized or maximized to the limits of the browser tab window as normal.

Stop GUI Session

• To stop the GUI session, do the following, SessionID is the ID listed above, for example "1" in the above example.

gui stop SessionID
