!!! important "CUDA-aware MPI"
When running CUDA applications using MPI for interprocess communication you need to additionally load the modules
that enable CUDA-aware MPI which may provide improved performance.
Those are `UCX-CUDA` and `UCC-CUDA` which supplement the `UCX` and `UCC` modules respectively.
Some modules, like NCCL`, load those automatically.
