[Boost-users] mpi all reduce with std::vector and back_inserter

Hello, I have a std::vectorstd::string vector at each CPU. I would like to "reduce" all vectors on all CPUs. For example: CPU 0: vec = [a, b, c, d] CPU 1: vec = [e, f, g, h] std::vectorstd::string myreduce; mpi::all_reduce( mpi com object, vec, myreduce, #); myreduce = [a, b, c, d, e, f, g, h] How can I do this? Should I replace my # with a back_inserter of the std::vector? Thx for help Phil
