Constructor & Destructor Documentation

def IMP.parallel.Manager.__init__	(		self,
			python = None,
			host = None,
			output = 'slave%d.output'
	)

Constructor.

Parameters

python	If not None, the command to run to start a Python interpreter that can import the IMP module. Otherwise, the same interpreter that the master is currently using is used. This is passed to the shell, so a full command line (including multiple words separated by spaces) can be used if necessary.
host	The hostname that slaves use to connect back to the master. If not specified, the master machine's primary IP address is used. On multi-homed machines, such as compute cluster headnodes, this may need to be changed to allow all slaves to reach the master (typically the name of the machine's internal network address is needed). If only running local slaves, 'localhost' can be used to prohibit connections across the network.
output	A format string used to name slave output files. It is given the numeric slave id, so for example the default value 'slave%d.output' will yield output files called slave0.output, slave1.output, etc.

Member Function Documentation

def IMP.parallel.Manager.add_slave	(		self,
			slave
	)

Definition at line 678 of file parallel/__init__.py.

def IMP.parallel.Manager.get_context	(		self,
			startup = None
	)

Create and return a new Context in which tasks can be run.

Parameters

startup

If not None, a callable (Python function or class that implements the __call__ method) that sets up the slave to run tasks. This method is only called once per slave. The return values from this method are passed to the task object when it runs on the slave.

Returns

A new Context object.
