[IPython-User] Start ipcluster with pure scheme

This issue was killing me:

I have been running about 65000 tasks at a time and was just watching
the controller spin around. I tried to start to a cluster with the pure
task scheduler but I get a warning message. I was wondering what the
correct way to do this is as I didn't see it in the docs.

ipcluster start --n=6 --scheme=pure

I have installed the latest dev version from git so I'm guessing this
issue will go away for me but I'd still like to know how to set the
taskscheduler from the command line.

Is the best way to create a profile and then configure that?
ipython profile create mycluster --parallel
