| + | 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. |

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. |

| |
| − | | |
| − | =Step 3: Connect to Xpra Session from the client side=
| |
| − | ==Linux:==
| |
| − | Xpra is typically automatically added to your path during installation, so you can connect to your running xpra instance using the following syntax where $USERNAME is your UF GatorLink user-name, $SERVERNAME is the server where your application is running inside xpra, and $PORT is the X11 port you assigned when you started your application.
| |
| − | | |
| − | xpra attach ssh:$USERNAME@$SERVERNAME:$PORT
| |
| − | | |
| − | As an example:
| |
| − | <pre>
| |
| − | testuser@jr-physics:~$ xpra attach ssh:testuser@i21a-s3.rc.ufl.edu:143 --desktop-scaling=on --dpi=96
| |
| − | </pre>
| |
| − | | |
| − | [[File:Hpg2-gui-matlab2.png|thumbnail|center|MatLab running via Xpra under slurm]] | |
| − | | |
| − | ==MAC OS:== | |
| − | Navigate to the folder that contains the xpra executable:
| |
| − | <pre>
| |
| − | cd /Applications/Xpra.app/Contents/MacOS
| |
| − | </pre>
| |
| − | | |
| − | Second, connect to your running xpra instance using the following syntax where $USERNAME is your GatorLink user-name, $SERVERNAME is the server where your application is running inside xpra, and $PORT is the X11 port you assigned when you started your application.
| |
| − | <pre>
| |
| − | ./Xpra attach ssh:$USERNAME@$SERVERNAME:$PORT | |
| − | </pre>
| |
| − | | |
| − | Example:
| |
| − | <pre>
| |
| − | ./Xpra attach ssh:test-user@i21a-s3.rc.ufl.edu:143 --desktop-scaling=on --dpi=96
| |
| − | </pre>
| |
| − | | |
| − | ==Microsoft Windows==
| |
| − | First, navigate to the install location of xpra (normally C:\Program Files (x86)\Xpra\).
| |
| − | ;In MobaXterm:
| |
| − | cd /drives/c/Progam\ Files\ \(x86\)/Xpra/
| |
| − | | |
| − | Second, connect to your running xpra instance using the following syntax where $USERNAME is your GatorLink user-name, $SERVERNAME is the server where your application is running inside xpra, and $PORT is the X11 port you assigned when you started your application.
| |
| − | | |
| − | ./xpra attach ssh:$USERNAME@$SERVERNAME:$PORT
| |
| − | | |
| − | ;Example:
| |
| − | | |
| − | <pre>
| |
| − | ./xpra attach ssh:testuser@i21a-s3.rc.ufl.edu:143 --desktop-scaling=on --dpi=96

| |
| − | | |
| − | ;NOTE: If you close the window using the close button, this will exit your application just like a native application. If you want to simply detach the session and come back later, please follow the ''detaching xpra session'' instructions below
| |
| − | | |
| − | =Step 4: Detaching Xpra Session=
| |
| − | These instructions allow you to detach a running xpra client without closing the application.
| |
| − | | |
| − | ==Linux and MAC OS==
| |
| − | In the original terminal where you activated the client, simply press Control-C to detach the session.
| |
| − | | |
| − | <pre>
| |
| − | 2016-04-06 15:18:17,173 Attached to ssh:testuser@i21a-s3.rc.ufl.edu:143 (press Control-C to detach)
| |
| − | ^C
| |
| − | got signal SIGINT, exiting
| |
| − | 2016-04-06 15:18:42,513 Connection lost
| |
| − | </pre>
| |
| − | | |
| − | You can re-attach to the running application using the ''xpra attach'' command as described in the instructions above.
| |
| − | | |
| − | ==Windows==
| |
| − | * Start a new console and navigate to the xpra directory as shown above. | |
| − | * Run the following command where $USERNAME is your UF GatorLink user-name, $SERVERNAME is the server where your application is running inside xpra, and $PORT is the X11 port you assigned when you started your application. | |
| − | | |
| − | ./xpra detach ssh:$USERNAME@$SERVERNAME:$PORT
| |
| − | | |
| − | ;Example:
| |
| − | <pre>
| |
| − | cd "C:\Program Files (x86)\Xpra"
| |
| − | ./xpra detach ssh:testuser@i21a-s3.rc.ufl.edu:143
| |
| − | </pre>
| |
| − | | |
| − | ;Note: If you are using mobaXterm, you can press Control-C in the mobaXterm window to detach, just like using the Linux client.
| |
| − | | |
| − | =Startup Scripts=
| |
| − | Some applications that require key command line parameters for launching, are more convienent to wrap with a startup script. Here is an annotated version and some application examples. The executable file can be downloaded here: [[File:matlab-launch.sh.txt| matlab-launch.sh]]
| |
| − | | |
| − | ==Matlab Example==
| |
| − | The first line of the launch script should set which shell type to use. On HiPerGator systems, the default shell is bash.
| |
| − | <pre>
| |
| − | #!/bin/bash
| |
| − | </pre>
| |
| − | | |
| − | Next, load the modules required for the application:
| |
| − | <pre>
| |
| − | module load matlab;
| |
| − | </pre>
| |
| − | | |
| − | Finally, enter the launch command for the GUI application:
| |
| − | <pre>
| |
| − | matlab -nosplash -desktop
| |
| − | </pre>
| |
| − | | |
| − | Once the script is saved, you will need to make it executable to run as an application wrapper. This can be done with the "chmod" command:
| |
| − | <pre>
| |
| − | [testuser@gator3 ~]$ chmod u+x matlab-launch.sh
| |
| − | </pre>
| |
| − | | |
| − | Below are some other application launch script examples:
| |
| − | ==Other Examples==
| |
| − | ===MZmine===
| |
| − | <pre>
| |
| − | #!/bin/bash
| |
| − | module load mzmine;
| |
| − | startMZmine_Linux.sh;
| |
| − | </pre>
| |
| − | | |
| − | MZmine with 8GB of memory:
| |
| − | <pre>
| |
| − | #!/bin/bash
| |
| − | | |
| − | module load mzmine
| |
| − | | |
| − | export _JAVA_OPTIONS="-Xmx8g"
| |
| − | | |
| − | startMZmine_Linux.sh
| |

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. We'd like to acknowledge an Open Source Xpra Project for creating software we built our GUI sessions on top of.
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.
