Virtual Application Environment

For the Virgo Compute Cluster IT provides multiple container-based OS images to choose from.

See https://hpc.gsi.de/virgo/platform/software.html#application-environment

The software in theses VAEs is normally provided via spack. The software provided by spack is also available on the interactive LinuxFarm but has to be initialized:

» . /cvmfs/vae.gsi.de/debian10/spack-0.19/vaesoft/spack/share/spack/setup-env.sh

This will make spack available and software packages can be searched and loaded.

Examples:

» spack list
