Tutorial 6 is a newer version of Tutorial 4 and 5. This is all about pbdZMQ+remoter+pbdCS+pbdR packages using Linux as a clusters with 3 MPI processes and windows as a client. The server has ip address "192.168.56.101" which is a XUbuntu system run in a VM where the host is Windows 8. A newer demo can be found on my github repo at snoweye/user2016.demo or in next.
