# - Start using the Windows HPC Server 2008 scheduler
# - Start using PBS
# - Start using SSH

# SSH launchers
#-----------------------------------------------------------------------------

# ipclusterz can be used to launch controller and engines remotely via ssh.
# Note that currently ipclusterz does not do any file distribution, so if
# machines are not on a shared filesystem, config and json files must be
# 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.

# set the ssh cmd for launching remote commands. The default is ['ssh']

# Set the arguments to be passed to ipcontrollerz
# note that remotely launched ipcontrollerz will not get the contents of 
# the local ipcontrollerz_config.py unless it resides on the *remote host*
# in the location specified by the --cluster_dir argument.

# c.SSHEngineSetLauncher.engine_args = ['--mpi', 'mpi4py']

# 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 [e-mail] with a special json connector location.
# c.SSHEngineSetLauncher.engines = {'my.example.com' : 3,
