The latest stable version of Singularity has been deployed on the ARC-TS clusters.
Singularity version 2.5.0 release includes fixes for several high and medium severity security issues. Full release notes can be found at the Singularity github project page.
We have also added default mount bindings that will map in the /home and /scratch directories into any Singularity container when it’s run on the cluster.
