std::vector<T> b(a.size());
if (!all)

else
MPI_Allreduce((void *)a.data(), b.data(), a.size(), mpi_datatype<T>(), op, c.get());
return b;
}示例2:
template <typename T> REQUIRES_IS_BASIC(T, T) mpi_reduce(T a, communicator c = {}, int root = 0, bool all = false, MPI_Op op = MPI_SUM) {
T b;
auto d = datatype<T>();
if (!all)
MPI_Reduce(&a, &b, 1, d, op, root, c.get());
