Singularity is a container platform: it lets you create and run containers that package up pieces of software in a way that is portable and reproducible. With a few basic commands, you can set up a workflow to run on Pawsey systems using Singularity. This page introduces how to get or build a Singularity container image and run that image on HPC systems. |

Depending on the cluster, different Singularity modules may be available:
Cluster | singularity/VV-mpi | singularity/VV-mpi-gpu | singularity/VV-nompi |

| Setonix (HPE Cray Ex) | Xyes | X | Garrawarla (GPU) | X | X | Xyes | yes | no | no |
These modules differ on the flavour of the MPI library they bind mount in the containers at runtime, and on whether or not they also bind mount the required libraries for CUDAGPU-aware MPI:
singularity, /VV-mpi: Cray MPI (Setonix) or Intel MPI (other clusters). All ABI compatible with MPICHsingularity/VV-mpi-gpu: Cray MPI (Setonix) or Intel MPI (othersother clusters). All ABI compatible with MPICH. With GPU-aware MPI.singularity/VV-nompi:For applications that do not require mpi communications (commonly Bioinformatics applications)singularity/VV-openmpi: OpenMPIsingularity-openmpi-gpu: OpenMPI built with CUDA support and any other libraries required by CUDA-aware MPI (for example:gdrcopynohost:For applications that require total isolation from host environment (commonly Bioinformatics applications)
Features of the modules
These singularity modules set important environment variables to provide a smoother and more efficient user experience. Modules set several key environment variables
