I am using ipyparallel on a PBS cluster. I set up a profile using the method outlined under "Using ipcluster in PBS mode" in the help document. That all seemed to work nicely, however, now I don't know how to run my ipython code/notebook. I can start the cluster using $ ipcluster start --profile=pbs -n 128 but then I when I run my notebook, it says, it can't find the engines. I set Client(profile='pbs') but that didn't seem to help. Any suggestions?
