An IPython cluster consists of 1 controller and 1 or more engines.
This command automates the startup of these processes using a wide
range of startup methods (SSH, local processes, PBS, mpiexec,
Windows HPC Server 2008). To start a cluster with 4 engines on your
local host simply do 'ipcluster start --n=4'. For more complex usage
you will typically do 'ipython profile create mycluster --parallel', then edit
configuration files, followed by 'ipcluster start --profile=mycluster --n=4'.

 N/A ALREADY_STARTED 10 N/A ALREADY_STOPPED 11 N/A NO_CLUSTER 12 N/A start_help Start an IPython cluster for parallel computing

Start an ipython cluster by its profile name or cluster
directory. Cluster directories contain configuration, log and
security related files and are named using the convention
'profile_<name>' and should be creating using the 'start'
subcommand of 'ipcluster'. If your cluster directory is in 
the cwd or the ipython directory, you can simply refer to it
using its profile name, 'ipcluster start --n=4 --profile=<profile>`,
otherwise use the 'profile-dir' option.
 N/A stop_help Stop a running IPython cluster

Stop a running ipython cluster by its profile name or cluster
directory. Cluster directories are named using the convention
'profile_<name>'. If your cluster directory is in 
the cwd or the ipython directory, you can simply refer to it
using its profile name, 'ipcluster stop --profile=<profile>`, otherwise
use the '--profile-dir' option.
 N/A engines_help Start engines connected to an existing IPython cluster

Start one or more engines to connect to an existing Cluster
by profile name or cluster directory.
Cluster directories contain configuration, log and
security related files and are named using the convention
'profile_<name>' and should be creating using the 'start'
subcommand of 'ipcluster'. If your cluster directory is in 
the cwd or the ipython directory, you can simply refer to it
using its profile name, 'ipcluster engines --n=4 --profile=<profile>`,
otherwise use the 'profile-dir' option.

        to use various batch systems to launch your engines, such as PBS,SGE,MPIExec,etc.
        Each launcher class has its own set of configuration options, for making sure
        it will work in your environment.
        
        You can also write your own launcher, and specify it's absolute import path,
        as in 'mymodule.launcher.FTLEnginesLauncher`.
        
        Examples include:
        
            LocalEngineSetLauncher : start engines locally as subprocesses [default]
            MPIExecEngineSetLauncher : use mpiexec to launch in an MPI environment
            PBSEngineSetLauncher : use PBS (qsub) to submit engines to a batch queue
            SGEEngineSetLauncher : use SGE (qsub) to submit engines to a batch queue
            SSHEngineSetLauncher : use SSH to start the controller
                                Note that SSH does *not* move the connection files
                                around, so you will likely have to do this manually
                                unless the machines are on a shared file system.
