description = """
LUMI provides containers for AI applications in /appl/local/containers,
in the sif-images, tested-containers and easybuild-sif-images subdirectories.

These containers require access to the Slingshot network for good RCCL and MPI
performance, and most users also want transparent access to their files. 

The bindings set up by this module take care of this.

Note that the precise bindings may be different for some containers, and may
also change over time as the MPI and libfabric libraries on the system change.
This module is certainly not a generic solution for all containers, but worked
for the PyTorch, Tensorflow, JAX, rocm and mpi4py containers in 
/appl/local/containers when developed in early 2025.

The module should not be used with any other container binding module.
