Assign component to a defined worker process

[Austin Holland]

Is it possible when registering a component to assign a component to a defined worker.  I have some components which really do a lot of work and perhaps should be assigned to their own process.  So I am instituting some changes, but here is an example.  And it would be nice if each Component was assigned to a specific worker.  

class RTapp(Component):

  def __init__(self):

    super(RTapp,self).__init__()

    self.worker=Worker(process=True,workers=6).register(self)

    

    self.subnet_trigger=SubnetTrigger().register(self)

    self.wf=WaveForm().register(self)

    self.eq=Earthquake().register(self)

    self.report=Report().register(self)

I was going to use a node server but am passing class instances around and it dawned on me that won't work.

Hi,

You'd probably want to start that componnet

or component graph in "process mode"

which uses the bridge to do PIC between the child

and parent.

It's a bit different to Worker which just wraps around

multiprocessing.Pool.

But if you have issues pickling your objects this won't work either.

Unless you use a different serialization.

cheers

Is there a good example of doing that out there somewhere?

[James Mills]

Other than hello_bridge.py in examples/ [1] no not really.

If you give me a very simple use-case I'd be more

than happy to write a more specific example.

cheers
