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

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
