Hi everyone,

I'm following the instructions in the Aug 29 2008 manual for parallel
computing, and have been having some problems; reading back through the
posts, I've noticed nothing to help (please, correct me if I'm wrong!).

If I start my cluster with:

$ ipcluster -n 4 &

Then, with IPython, 0.9.rc1:

In [1]: from IPython.kernel import client

In [2]: tc = client.TaskClient()

I get:

... traceback information....

ValueError: not a furl or a file containing a furl:

If I follow the instructions printed by the shell during cluster startup:

In [1]: from ipython1.kernel import client   # Differs from the manual

In [2]: mec = client.MultiEngineClient(('',10105)) # Differs.

All seems well.  The same occurs when I follow the 'Quickstart Task
Farming' section:

In [3]: tc = client.TaskClient(('',10105))

is fine, but

In [3]: tc = client.TaskClient()  # as per the manual.


TypeError: TaskClient() takes exactly 1 argument (0 given)

I'm wondering, have I made a mistake with my installation?

Best regards,
