Starting an Interactive application
To start an interactive application, first select the application you would like to start from the "Interactive Applications menu". Then you will see a form with the SLURM options available for that application. Fill in the fields with the resources you would like allocated for this application session.
General Form Fields
Version: Select the application version This defines the version of the application you want to load.
We recommend leaving the following fields at the default of 1:
- Number of MPI Tasks (--ntasks)
- Number of CPU cores requested per MPI task (--cpus-per-task, -p)
- Maximum memory requested for this job in Gigabytes (--mem, -m)
- Note: If you are using advanced memory options in Additional SLURM Options below, then leave this blank.
- Time Requested for this job in hours (--time, -t)
We recommend leaving the following fields blank as default
- SLURM Account (--account, -A):
- QoS (Required if custom Account is set, --qos, -q)
- Cluster partition (--partition, -p)
- Generic Resource Request (--gres)
- Additional SLURM Options
You can have multiple copies of the same application running at the same time by submitting the form multiple times. Then select "Launch" to submit your job request.
Display Environment on the Console
You can use the "Console" Interactive application from the OOD menu to get a console session enabled with the frame-buffer. To do this:
- login to https://ood.rc.ufl.edu
- Select the "Console" Application
- Interactive Apps -> Console
- Fill in the form with your job resource request (please make sure to ask for at least 4 GB of RAM to make sure you have enough to render the frame buffers) and then select "Launch" at the bottom of the form. For specific parameters, see the Open OnDemand Access page
- Select "Launch Console" from the "My Interactive Sessions" page once your job starts.
This console session will open in your web browser and will have both the DISPLAY variable set and the X11 server started.

Once a job has started, you can connect using the "My Interactive Applications" menu.
- Select this menu and you will see a connection box for each application you have running and pending.
- Once the job starts, a Launch (App Name) icon will appear.
- Select this link to open a new browser window connecting you to your application.
Connecting to a HWGUI application
To use the hardware accelerated resources with your interactive sessions, please select the hwgui partition from the partition list when submitting your job resource form.
Additionally, many applications that require hardware acceleration by default have been added under the HWGUI Apps section of the Interactive Apps menu.
Job Connect Card
This section outlines several of the key features of the job connect card:
- JobID: This is the SLURM JobID for this job
- Delete: This will cancel a running job, (or delete the session if the job has already ended)
- OOD Session ID: This is the unique identifier for the OOD session for this job, can be clicked to bring up the OOD log directory for troubleshooting
- Image Quality: This setting controls the quality of the visual interface at the source, use a lower setting for slower internet connections
- Compression: This setting adjusts the amount of CPU based compression used for the NoVNC connection, use higher settings for slower connections but note it will increase CPU usage on both the job and client
