Hi Ralph, Helps a lot! But the option "--report-uri" is unable to mpirun. After some searches in OpenMPI lists I found a way to run:
1) ompi-server -d --report-uri urifile & -----> (must be always running) 2) mpirun -ompi-server file:urifile -np 1 publish-test 3) mpirun -ompi-server file:urifile -np 1 connect-test Thank you for the links.
