Put your scientific workflows, software and libraries in a Singularity container and run it on UBELIX


Work interactively

Submit an interactive SLURM job and then use the shell command to spawn an interactive shell within the Singularity container:

srun --time=01:00:00 --mem-per-cpu=2G --pty bash
singularity shell <image>

Execute the containers “runscript”

#SBATCH --partition=all
#SBATCH --mem-per-cpu=2G

singularity run <image>   #or ./<image>

Run a command within your container image

singularity exec <image> <command>

singularity exec container.img cat /etc/os-release

Bind directories

Per default the started application (e.g. cat in the last example) runs withing the container. The container works like a seperate machine with own operation system etc. Thus, per default you have no access to files and directories outside the container. This can be changed using binding paths.

If files are needed outside the container, e.g. in your HOME you can add the a path to SINGULARITY_BINDPATH="src1[:dest1],src2[:dest2]. All subdirectories and files will be accessible. Thus you could bind your HOME directory as:

# or simply
