Merge pull request #1768 from minrk/parallelmagics Update parallel magics They now display all output, so you can do parallel plotting or other actions with complex display. The `px` magic has now both line and cell modes, and in cell mode finer control has been added about how to collate output from multiple engines. Tests, docs and example notebook added.

Simple task farming example

In [3]:
from IPython.parallel import Client

A Client.load_balanced_view is used to get the object used for working with load balanced tasks.

In [4]:
rc = Client()
v = rc.load_balanced_view()

Set the variable d on all engines:

In [5]:
rc[:]['d'] = 30

Define a function that will be our task:

In [6]:
def task(a):
    return a, 10*d, a*10*d

Run the task once:

In [7]:
ar = v.apply(task, 5)

Print the results:

In [8]:
print "a, b, c: ", ar.get()
a, b, c:  [5, 300, 1500]
