Launch a Desktop Application

To launch a Desktop Application, kindly click on the link from the Open Ondemand Welcome page :

It will redirect you to the available application list as per below. Let's assume that as an example, we would like to launch Blender. For that, click on it from the application list :

Next step will be to set-up your job, by referring the following options :

Option	Required	Description	SBATCH equivalent
Number of nodes	Yes	The number of nodes to allocate	#SBATCH --nodes
Account	Yes	The Slurm project account to use, e.g. p000000	#SBATCH --account
QOS	Yes	The QOS to request	#SBATCH --qos
Reservation	No	The Slurm reservation	#SBATCH --reservation
Timelimit	Yes	Time allocation to request	#SBATCH --time
Partition	Yes	The node type to allocate	#SBATCH --partition

Once your job is set, click on the 'Launch' button which will trigger a new Job on MeluXina and automatically redirect you on a new page. Your new Job will be displayed and showing it state. Once your job turns to 'Running', click on 'Launch Blender' :

This will automatically open a VNC VM into a new Tab of your internet browser :

Kindly wait until Blender get loaded and launched in the VM. Once loaded, it will automatically launch a session as shown below :

You have now launched Blender from your Open Ondemand session!

Please note that the same logic applies for any Desktop Application available on Open Ondemand
