Singularity is an open source container platform designed to be simple, fast, and secure.
Singularity is optimized for EPC and HPC workloads, allowing untrusted users to run untrusted containers in a trusted way.
This repo creates an environment to use Singularity on Barge with Vagrant instantly.
$ vagrant up
That's it.
Now you can use singularity on the Barge VM.
$ vagrant ssh
