Your cluster is up and running.

For interactive use, you can make a Remote Controller with:

import ipython1.kernel.api as kernel
ipc = kernel.RemoteController(('127.0.0.1',10105))

You can then cleanly stop the cluster from IPython using:

ipc.killAll(controller=True)

You can also hit Ctrl-C to stop it, or use from the cmd line:

kill -INT 4333
