=== Interactive Job Blender ===

Connect to the [[calcoloscientifico:userguide:gui|Graphical User Interface]] using Remote Desktop Protocol (RDP).

Right click on the desktop and select "Open Terminal".

Alternatively, open an X11 connection to the login machine:

<code>
ssh -X name.surname@login.hpc.unipr.it
</code>

To run Blender 4.3.2 on 1 node of the ''gpu'' partition using 6 cores and up to 80 GB of memory, start srun like this:

<code>
srun \
    --job-name=blender \
    --nodes=1 \
    --ntasks-per-node=1 \
    --cpus-per-task=6 \
    --mem=80G \
    --partition=gpu \
    --qos=gpu \
    --gres=gpu:p100:1 \
    --time=0-01:00:00 \
    --pty \
    --x11 \
    bash
</code>

Once you have accessed the required resources with srun, run the commands:

<code>
module load apptainer
module load blender/4.3.2
blender.sh
</code>

In the new shell launch Blender:

<code>
blender-softwaregl
</code>
