# ipclusterz can be used to launch controller and engines remotely via ssh.
# Note that currently ipclusterz does not do any file distribution, so if

# distributed.  For this reason, the reuse_files defaults to True on an
# ssh-launched Controller.  This flag can be overridded by the program_args
# attribute of c.SSHControllerLauncher.

# the local ipcontrollerz_config.py unless it resides on the *remote host*
# in the location specified by the --cluster_dir argument.

# SSH engines are launched as a dict of locations/n-engines.
# if a value is a tuple instead of an int, it is assumed to be of the form
# (n, [args]), setting the arguments to passed to ipenginez on `host`.
# otherwise, c.SSHEngineSetLauncher.engine_args will be used as the default.

# In this case, there will be 3 engines at my.example.com, and
# 2 at you@ipython.scipy.org with a special json connector location.
