Functions
template<typename A> requires (is_regular_or_view_v<A> and std::decay_t<A>::is_stride_order_C())
auto	nda::mpi_gather (A const &a, mpi::communicator comm={}, int root=0, bool all=false)
	Implementation of an MPI gather for nda::basic_array or nda::basic_array_view types.
template<typename A1, typename A2> requires (is_regular_or_view_v<A1> and std::decay_t<A1>::is_stride_order_C() and is_regular_or_view_v<A2> and std::decay_t<A2>::is_stride_order_C())
void	nda::mpi_gather_into (A1 const &a_in, A2 &&a_out, mpi::communicator comm={}, int root=0, bool all=false)
	Implementation of an MPI gather for nda::basic_array or nda::basic_array_view types that gathers directly into an existing array/view.
