Well, your initial usage looks correct - you don’t launch ompi-server via mpirun. However, it sounds like there is probably a bug somewhere if it hangs as you describe.
Scratching my head, I can only recall less than a handful of people ever using these MPI functions to cross-connect jobs, so it does tend to fall into disrepair. As I said, I’ll try to repair it, at least for 3.0. > On Mar 19, 2017, at 4:37 AM, Adam Sylvester <op8...@gmail.com> wrote: > > I am trying to use ompi-server with Open MPI 1.10.6.
