Singularity

[pvandyken]

Singularity will eventually be one of the core features of the library. The computecanada clusters present unique challenges for pulling and organizing images, and the recommended procedures should be baked into easy-to-use scripts. Ideally, the solution will still be generalizable to other compute clusters.

The basic scheme will be as follows:

• Images will be pulled using the 2-step method recommended by computecanada (see here).
• Pulled images will be stored in a location of the user's choosing. In the case of computecanada, they will be on the project space in the user's personal file. Any arbitrary location could be specified, however.
• Users should also be able to indicate a central image repository on the cluster to which they have read access. This saves space by allowing users to share commonly used packages. The common images should be symlinked in the user's personal directory. kslurm should manage this symlinking process
