• Apptainer on Rivanna

    Introduction Apptainer is a continuation of the Singularity project (see here). Effective December 18, 2023 we will be migrating from Singularity to Apptainer. Containers created by Singularity and Apptainer are mutually compatible as of this writing, although divergence is to be expected. One advantage of Apptainer is that users can now build container images natively on Rivanna. Apptainer on Rivanna (after 12/18/2023) Apptainer is available as a module. The RC staff has also curated a library of pre-prepared Apptainer container images for popular applications as part of the shared software stack. Descriptions for these shared containers can be found via the module avail and module spider commands.
