Install with the EasyBuild-user module in partition/container:

module load LUMI partition/container EasyBuild-user
eb mpi4py-3.1.4-rocm-5.4.5-python-3.10-singularity-20231110.eb

The module will be available in all versions of the LUMI stack and in the CrayEnv stack.

To access module help after installation use module spider mpi4py/3.1.4-rocm-5.4.5-python-3.10-singularity-20231110.

description = """
This module provides a container with mpi4py %(version)s and cupy. 

The module defines a number of environment variables:
*   SIF and SIFMPI4PY: The full path and name of the Singularity SIF file 
    to use with singularity exec etc.
*   SINGULAIRTY_BINDPATH: Mounts the necessary directories from the system,
    including /users, /project, /scratch and /flash so that you should be
    able to use your regular directories in the container.
*   RUNSCRIPTS and RUNSCRIPTSMPI4PY: The directory with some sample
    runscripts.


Note that this container uses a Conda environment internally. When in
the container, the command to activate the container is contained in the
environment variable WITH_CONDA.
