Backport PR : ipcluster broken with any batch (PBS/LSF/SGE)...

Backport PR : ipcluster broken with any batch (PBS/LSF/SGE) I have setup ipcluster_config.py to start with LSF: ``` c.IPClusterStart.controller_launcher_class = 'LSF' c.IPClusterStart.engine_launcher_class = 'LSF' ``` But the ipcluster command fails to start the engines: ``` ipcluster start --profile=lsf -n 10 ``` The problem is fixed if I add quotes to the launch command string ```cmd``` in ```launcher.py```. ``` diff --git a/IPython/parallel/apps/launcher.py b/IPython/parallel/apps/launcher.py index e752d2a..6035303 100644 --- a/IPython/parallel/apps/launcher.py +++ b/IPython/parallel/apps/launcher.py @@ -73,7 +73,7 @@ WINDOWS = os.name == 'nt' # Paths to the kernel apps #----------------------------------------------------------------------------- -cmd = "from IPython.parallel.apps.%s import launch_new_instance; launch_new_instance()" +cmd = "\"from IPython.parallel.apps.%s import launch_new_instance; launch_new_instance()\"" ipcluster_cmd_argv = [sys.executable, "-c", cmd % "ipclusterapp"] ```
