      GPUPackInfo: add asynchronous (un)packing capabilities · 6bfe8c59
      João Victor Tozatti Risso authored
      Changes introduced in this commit are the following:
      
      - CUDA streams: Add support for asynchronous (un)packing operations using CUDA
        streams in cuda::communication::GPUPackInfo. Through asynchronous operations
        it is possible to overlap GPU computation and MPI communication in simulations
        (e.g. LBM simulations). Asynchronous copies in CUDA require pinned memory on
        the host, and for that purpose a staging buffer is introduced (i.e.
        cuda::communication::PinnedMemoryBuffer) in the cuda module, which is used to
        stage data between the GPU and the MPI buffers.
      
      - zyxf layout: Add zyxf field layout support in GPUPackInfo through extensions
        of the functions in cuda::GPUCopy.
      
      - Extended GPUPackInfo test: Add stream and zyxf layout tests to the
        GPUPackInfoTest to test the proposed implementation.
      
      - Extended Kernel: add CUDA stream and shared memory configuration support in
        cuda::Kernel class.
