This meeting will be recorded

1. Demo - singularity-hpc (by @vsoch). Singularity HPC is optimized for managing containers in an HPC environment. You can use shpc if you are:
   • a linux administrator wanting to manage containers as modules for your cluster
   • a cluster user that wants to maintain your own folder of custom modules
   • a cluster user that simply wants to pull Singularity images as GitHub packages.
2. SingularityCE release & development update.
3. Any other business / questions.
