On the developer branch, LinearAlgebra::distributed::Vector supports storing its elements on a CUDA device, but the values are copied to the CPU for MPI communication. The pull request https://github.com/dealii/dealii/pull/7303 allows to use CUDA-aware MPI instead but the memory transfer needs to be optimized.
