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.
To see all available configurables, use --help-all.
EXAMPLES
ipengine --ip=192.168.0.1 --port=1000
# connect to hub at ip and port
ipengine --log-to-file --log-level=DEBUG
# log to a file with DEBUG verbosity
