Don't reset the readline completer after each prompt...
Don't reset the readline completer after each prompt This makes it impossible to setup a custom completer. The comment says that "we must ensure that our completer is back in place," but I don't see why. All that does it make it impossible to use a different completer. One can trick IPython into not doing this by monkeypatching ip.has_readline to False, but then certain features like multiline editing are no longer enabled. See https://github.com/davidhalter/jedi/pull/321.

Simple task farming example

In [1]:
from IPython.parallel import Client

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

In [2]:
rc = Client()
v = rc.load_balanced_view()

Set the variable d on all engines:

In [3]:
rc[:]['d'] = 30

Define a function that will be our task:

In [4]:
def task(a):
    return a, 10*d, a*10*d

Run the task once:

In [5]:
ar = v.apply(task, 5)

Print the results:

In [6]:
print "a, b, c: ", ar.get()
a, b, c:  [5, 300, 1500]
