Capabilities

Since capabilities are decided by the administrator for your distribute cluster, capabilities are cluster-specific.

One recommendation made to administrators, though, is that the capabilities apptainer and gpu are included to denote access to an apptainer binary on the system and the system containing a NVIDIA gpu, respectively.

As long as these capabilities are specified, users can bundle their own dependencies in an apptainer image and execute easily. If your group intends to make heavy use of python configurations across multiple computers, you may run into robustness issues: these workflows are frail, easy to break, and hard to maintain.
