    - [CUDA](https://docs.nvidia.com/cuda/index.html) 9.0 or later -- for

      computations on Nvidia GPUs.

    - [MPI](https://en.wikipedia.org/wiki/Message_Passing_Interface) -- TNL can

      use an MPI library such as [OpenMPI](https://www.open-mpi.org/) for

      distributed computing. For distributed CUDA computations, the library must

      be [CUDA-aware](

      a library implementing the MPI-3 standard for distributed computing (e.g.

      [OpenMPI](https://www.open-mpi.org/)). For distributed CUDA computations,

      the library must be [CUDA-aware](

      https://developer.nvidia.com/blog/introduction-cuda-aware-mpi/).
