๐Ÿ› mpi4py bug on Sunspot

Simple reproducer:

  1. Load my anl_24_q2_release conda environment:

    #[08:42:38 AM][foremans@x1922c2s3b0n0][~]
    $ eval "$(~/miniconda3/bin/conda shell.zsh hook)" ; conda activate anl_24_q2_release
  2. Try python3 -c 'from mpi4py import MPI'

    • fails โŒ
    # [08:44:41 AM][foremans@x1922c2s3b0n0][~][anl_24_q2_release]
    $ python3 -c 'from mpi4py import MPI'
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
    ImportError: /home/foremans/miniconda3/envs/anl_24_q2_release/lib/python3.9/site-packages/mpi4py/MPI.cpython-39-x86_64-linux-gnu.so: undefined symbol: MPI_Message_c2f
    [1]    14910 exit 1     python3 -c 'from mpi4py import MPI'
  3. Load correct modules:

    # [08:44:58 AM][foremans@x1922c2s3b0n0][~][anl_24_q2_release]
    $ module use /home/ftartagl/graphics-compute-runtime/modulefiles ; module load graphics-compute-runtime/agama-ci-devel-803.29 spack-pe-gcc/0.6.1-23.275.2 gcc/12.2.0 ; module use /soft/preview-modulefiles/24.086.0 ; module load oneapi/release/2024.04.15.001
         UMD: agama-ci-devel-803.29 successfully loaded:
         UMD: graphics-compute-runtime/agama-ci-devel-803.29
    
    Due to MODULEPATH changes, the following have been reloaded:
      1) mpich-config/collective-tuning/1024
    
    The following have been reloaded with a version change:
      1) intel_compute_runtime/release/agama-devel-736.25 => intel_compute_runtime/release/775.20     2) mpich/icc-all-pmix-gpu/52.2 => mpich/icc-all-pmix-gpu/20231026     3) oneapi/eng-compiler/2023.12.15.002 => oneapi/release/2024.04.15.001
  4. Retry with new modules:

    # [08:45:01 AM][foremans@x1922c2s3b0n0][~][anl_24_q2_release]
    $ python3 -c 'from mpi4py import MPI; print(MPI.__file__)'
    /home/foremans/miniconda3/envs/anl_24_q2_release/lib/python3.9/site-packages/mpi4py/MPI.cpython-39-x86_64-linux-gnu.so
