| − | You can run GUI Programs on HiPerGator, but running such applications on a remote server within a supercomputer and displaying them on your local client computer as if it were running there and making the interface sufficiently responsive is not as easy as simply running them locally. To accomplish this task we use [https://xpra.org Xpra software] - an open-source multi-platform persistent remote display server and client for forwarding applications and desktop screens. Full information on Xpra can be found in its [https://xpra.org/trac/wiki/Usage basic usage documentation] and the [https://xpra.org/manual.html Xpra manual]. Below we show the parts of Xpra documentation relevant to its function of running GUI Programs on HiPerGator.

| − | =Install Xpra Software on the Client Computer=
| + | Here you will find the information necessary to configure and run graphical user interface (GUI) applications on HiPerGator. The process is not complicated, but running a GUI on a remote server and displaying the windows on your local client computer with a sufficiently responsive interface is not as easy as simply running the application locally. We'd like to acknowledge an Open Source [https://xpra.org Xpra Project] for creating software we built our GUI sessions on top of. |
| − | Since Xpra is required on both ends of the connection you will have to have it installed on your local computer. Xpra client installation depends on the operating system running on your local machine and may require assistance of a system administrator if you do not have the authority to install new software. Once Xpra is installed on your client computer feel free to skip this step. Installation instructions are specific to the operating system running on your local computer:
| |
| − | : [[Xpra Windows Installation|Windows]]
| |
| − | : [[Xpra MacOS X Installation|MacOS X]] | |
| − | : [[Xpra Linux Installation|Linux]].

This can be done manually, as described above, but an easier method is to use [https://help.rc.ufl.edu/doc/Open_OnDemand#Display_Environment_on_the_Console Open OnDemand] since that will start an X11 server and allocate the frame buffer automatically. |

| |
| − | <div class="mw-collapsible-content" style="padding: 5px;">
| |
| − | If you want to run a simple application in which either the environment module name matches the name of the program you want to run or you've already loaded the environment module and know the name of the executable then the process is about as simple as launching a preset application
| |
| − | | |
| − | Load the application environment module if its name is different from the executable name
| |
| − | module load <application>/<version>
| |
| − | | |
| − | Launch the executable in a GUI session:
| |
| − | module load gui
| |
| − | launch_gui_session -e <application>
| |
| − | | |
| − | | |
| − | For example:
| |
| − | launch_gui_session -e molden
| |
| − | | |
| − | or:
| |
| − | module load gaussian gui
| |
| − | launch_gui_session gv
| |

| |
| − | | |
| − | ==Provided job script==
| |
| − | If you need to pass custom arguments to the application, load pre-requisite environment modules and so on you can provide a simple script (linux format text file) with the required commands as an argument to launch_gui_session.
| |
| − | | |
| − | Make sure to prepend the command that starts the program with xpra_start. For example, a following job script named '''my_molden.sh''' will use the molden/5.0 environment module and start molden with a particular model file:
| |
| − | module load molden/5.0
| |
| − | xpra_start 'molden /ufrc/data/tests/molden/boc-iso-1t.gjf'
| |
| − | | |
| − | Now, to launch molden with the above script run:
| |
| − | launch_gui_session -e molden -f my_molden.sh
| |
| − | | |
| − | ==Manual launch== | |
| − | If you prefer to talk directly to SLURM you can write a full job script complete with resource requirements, job name, output file, etc in the #SBATCH section and submit the script to SLURM manually.
| |
| − | | |
| − | Make sure you use the gui partition:
| |
| − | <nowiki>#</nowiki>SBATCH --partition=gui
| |
| − | and wrap your command with xpra_start as shown above.
| |
| − | | |
| − | You can use a job script for one of the application presets found in the '$HPC_GUI_JOB' directory once the 'gui' environment module is loaded as the base of your own job script.
| |
| − | | |
| − | =List GUI Sessions=
| |
| − | If you performed a manual launch or used the '-w' argument to the automated launcher command you'll have to manually check on your gui job. Check the job status with 'squeue -u $USER'. When the job starts you have to list the available xpra sessions using xpra_list_sessions command in the gui module. This command will refresh the Xpra session list and provide a convenient list of live Xpra sessions as well as client commands that can be copied and pasted into a terminal on the client machine.

| − | ;Example:
| |
| − | $ module load gui
| |
| − | $ xpra_list_sessions

| − | If you are working off campus, you will need to use the VPN to connect to the UF campus network using [https://connect.ufl.edu/it/wiki/Pages/glvpn-anyconnect-install.aspx AnyConnect VPN] or similar software. Please see: [https://vpn.ufl.edu https://vpn.ufl.edu] for additional information.

| − | ;Note
| |
| − | :if you close the application window using the close button in the top right (or left) corner, this will exit your application and terminate your SLURM gui session. Use 'Ctrl+c' key combination in the terminal windows where you ran the xpra attach command to disconnect the session if you plan to reconnect later.

The module gui/2 is no longer available. Use this page to know how to use GUI applications on Hipergator.
Here you will find the information necessary to configure and run graphical user interface (GUI) applications on HiPerGator. The process is not complicated, but running a GUI on a remote server and displaying the windows on your local client computer with a sufficiently responsive interface is not as easy as simply running the application locally.

X11 Forwarding
For the simplest case of running a lightweight GUI application for a very short time you can log into HiPerGator with
ssh -Y MYUSER@hpg.rc.ufl.edu
load the environment module your application is in and run it. Do not analyze data this way, but running a text editor, a web browser to log in and get an api token from a remote service or some other very short and lightweight operations are fine.
Open OnDemand
Normally the X11 DISPLAY variable is set once the X11 server is started. This can be done manually, as described above, but an easier method is to use Open OnDemand since that will start an X11 server and allocate the frame buffer automatically.
Open OnDemand provides a web-only interface to starting and attaching to GUI programs with seamless connections through web browsers. This service is available at the following URL:
https://ondemand.rc.ufl.edu
Many applications have their own interfaces, but other can also be launched by launching a HiPerGator Desktop and then opening the application with the desktop interface.
