Installing singularity
Singularity is already installed for you on both the training virtual machines and on darwin.
To install on your own machine, follow the instructions in the singularity user guide. We are using version 2.3 for this workshop to get the most up-to-date support for running applications that make use of GPU compute.
Installing singularity on your own machine (where you have root/sudo access) will let you create new images either from scratch or from the software that you have installed.
