BTW, is there an easy way to add a non-regression test for this command?

Thanks @jtriley. BTW I will soon have a much simpler version of the IPCluster plugin that does not require the SGE queue. It shares some code with the existing plugin but is quite different as well. Any suggestion for the name of the plugin?


@ogrisel I've been wanting to change the ipcluster plugin to not use SGE at all by default given that the current implementation takes up the entire SGE queue to run IPython parallel. Feel free to submit a pull request for this.


Alright! Do you want to maintain ipython 0.10 compat or shall I drop it as well?


I decided to drop the ipython 0.10 compat in #204 to simplify the code and future maintenance of the plugin.
