Alex and Matthew playing with python parallel programming

Then we copied the sshx script from the ipython1 distro into /imaging/local/linux/bin Then we did touch .bashrc to stop an sshx error message. Then (for the sake of argument) we made a tiny script to test with:

   1 controller = dict(host='l42',
   2                   engine_port=None, # default is 10105
   3                   control_port=None,
   4                   )
   5 
   6 # keys are hostnames, values are the number of engine on that host
   7 engines = dict(l31=2,
   8                l32=2,
   9                l33=2,
  10                l34=2,
  11                )

Then we ran ipcluster -f small_cluster.py

and got this:

Starting controller:
Starting engines:   
Sarting 2 engines on l34
Sarting 2 engines on l32
Sarting 2 engines on l33
Sarting 2 engines on l31

Your cluster is up and running.

For interactive use, you can make a MultiEngineClient with:

from ipython1.kernel import client
mec = client.MultiEngineClient(('l42',10105))

You can then cleanly stop the cluster from IPython using:

mec.kill(controller=True)
