Subject: [Boost-users] mpi all reduce with std::vector and back_inserter
From: Kraus Philipp (philipp.kraus_at_[hidden])

Hello,
I have a std::vector<std::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::vector<std::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
