User documentation

What is the module for?

LUMI offers a range of containers mostly for AI applications in /appl/local/containers:

  • Subdirectory sif-images: Link to the most recent version of a particular container.

  • Subdirectory tested-containers: Latest container builds, the content changes all the time.

  • Subdirectory easybuild-sif-images: Copies of current and former containers from tested-containers to keep a more stable repository which is needed for the EasyBuild modules that install containers and offer some extras (see, e.g., the PyTorch container).

These containers use the CXI provider and MPI libraries from the system to guarantee good performance for network communications through RCCL and MPI (also used by the Python package mpi4py). Furthermore, singularity on LUMI by default only gives you access to your home directory, but not to your data in /project, /scratch and /flash. This module sets the environment variable SINGULARITY_BIND which instructs singularity which files and directories from the system should be made available where in the container and takes care binding the necessary files for CXI, MPI and full file system access.

For most of these containers, there are also more complete modules available to ease working with them that can be installed through EasyBuild, e.g., for most containers for PyTorch, TensorFlow, jax, AlphaFold, rocm and mpi4py. The modules installed for those containers following the instructions on those pages in the LUMI Software Library already perform all necessary bindings. So when using these modules, one should not use singularity-AI-bindings.

Install

In short, the module can be installed once to be available in all versions of the CrayEnv and LUMI stacks:

module load LUMI partition/container EasyBuild-user
eb singularity-AI-bindings-24.03.eb

The long: If you will install more user-installable software from the LUMI Software Library, please check our documentation on installing software with EasyBuild in the LUMI documentation.

User-installable modules (and EasyConfigs)

Install with the EasyBuild-user module: 

eb <easyconfig> -r
To access module help after installation and get reminded for which stacks and partitions the module is installed, use module spider singularity-AI-bindings/<version>.
