NAME

       ipengine - start an IPython cluster engine

DESCRIPTION

       Start an IPython engine for parallel computing.

       IPython  engines  run  in  parallel  and  perform  computations  on  behalf of a client and controller. A
       controller needs to be started before the engines. The  engine  can  be  configured  using  command  line
       options or using a cluster directory.  Cluster directories contain config, log and security files and are
       usually  located  in  your  ipython  directory  and  named  as  "profile_name".  See  the  `profile`  and
       `profile-dir` options for details.

       Options -------

       Arguments  that  take  values  are  actually convenience aliases to full Configurables, whose aliases are
       listed on the help line. For more information on full configurables, see '--help-all'.

       --mpi

              enable MPI integration

       --log-to-file

              send log output to a file

       --debug

              set log level to logging.DEBUG (maximize logging output)

       --quiet

              set log level to logging.CRITICAL (minimize logging output)

       --init

       Initialize profile with default config files.
              This is equivalent

              to running `ipython profile create <profile>` prior to startup.

       --secure

              Use HMAC digests for authentication of messages.  Setting this flag will generate a  new  UUID  to
              use as the HMAC key.

       --no-secure

              Don't authenticate messages.

       --file=<Unicode> (IPEngineApp.url_file)

              Default:  ''  The  full  location  of  the  file  containing  the  connection  information for the
              controller. If this is not given, the file must be  in  the  security  directory  of  the  cluster
              directory.  This location is resolved using the `profile` or `profile_dir` options.

       -c <Unicode> (IPEngineApp.startup_command)

              Default: '' specify a command to be run at startup

       -s <Unicode> (IPEngineApp.startup_script)

              Default: '' specify a script to be run at startup

       --url=<Unicode> (EngineFactory.url)

              Default:  '' The 0MQ url used for registration. This sets transport, ip, and port in one variable.
              For example: url='tcp://127.0.0.1:12345' or url='epgm://*:90210'

       --ssh=<Unicode> (EngineFactory.sshserver)

              Default: '' The SSH server to use for tunneling connections to the Controller.

       --sshkey=<Unicode> (EngineFactory.sshkey)

              Default: '' The SSH private key file to use when tunneling connections to the Controller.

       --ip=<Unicode> (EngineFactory.ip)

              Default: '' The IP address for registration.  This is generally either  '127.0.0.1'  for  loopback
              only or '*' for all interfaces.

       --transport=<Unicode> (EngineFactory.transport)

              Default:  'tcp'  The  0MQ transport for communications.  This will likely be the default of 'tcp',
              but other values include 'ipc', 'epgm', 'inproc'.

       --port=<Int> (EngineFactory.regport)

              Default: 0 The port on which the Hub listens for registration.

       --location=<Unicode> (EngineFactory.location)

              Default: '' The location (an IP address) of the controller.  This is used for disambiguating URLs,
              to determine whether loopback should be used to connect or the public address.

       --timeout=<Float> (EngineFactory.timeout)

              Default:  5.0 The time (in seconds) to wait for the Controller to respond to registration requests
              before giving up.

       --profile-dir=<Unicode> (ProfileDir.location)

              Default: '' Set the profile location directly. This overrides the  logic  used  by  the  `profile`
              option.

       --profile=<Unicode> (BaseIPythonApplication.profile)

              Default: 'default' The IPython profile to use.

       --ipython-dir=<Unicode> (BaseIPythonApplication.ipython_dir)

              Default:  ''  The  name of the IPython directory. This directory is used for logging configuration
              (through profiles), history storage, etc. The default is usually $HOME/.ipython. This  option  can
              also be specified through the environment variable IPYTHONDIR.

       --log-level=<Enum> (Application.log_level)

              Default: 30 Choices: (0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL') Set the
              log level by value or name.

       --config=<Unicode> (BaseIPythonApplication.extra_config_file)

              Default: '' Path to an extra config file to load.  If specified, load this config file in addition
              to any other IPython config.

       --work-dir=<Unicode> (BaseParallelApplication.work_dir)

              Default: '/home/joe' Set the working dir for the process.

       --log-to-file=<Bool> (BaseParallelApplication.log_to_file)

              Default: False whether to log to a file

       --clean-logs=<Bool> (BaseParallelApplication.clean_logs)

              Default: False whether to cleanup old logfiles before starting

       --log-url=<Unicode> (BaseParallelApplication.log_url)

              Default: '' The ZMQ URL of the iplogger to aggregate logging.

       --cluster-id=<Unicode> (BaseParallelApplication.cluster_id)

              Default:  ''  String  id  to  add to runtime files, to prevent name collisions when using multiple
              clusters  with  a  single  profile  simultaneously.   When  set,  files  will   be   named   like:
              'ipcontroller-<cluster_id>-engine.json'  Since  this  is  text  inserted  into  filenames, typical
              recommendations apply: Simple character strings are ideal, and spaces  are  not  recommended  (but
              should generally work).

       --ident=<CUnicode> (Session.session)

              Default: '' The UUID identifying this session.

       --user=<Unicode> (Session.username)

              Default: 'joe' Username for the Session. Default is your system username.

       --keyfile=<Unicode> (Session.keyfile)

              Default: '' path to file containing execution key.
