Hi Daren,

I just created a simple workflow (see attachment) that counts up to

This works. But it isn't being distributed. I know, because it works
even if I remove the network connection - *so*, everything is
happening locally. I tried removing "localhost" from the list of
available slaves, but this doesn't help.
The reason that your workflow doesn't distribute is that there is no
director inside of the DistributedCompositeActor. If there is no
director, the actor will behavior as a normal composite actor. Please
put a director in your DistributedCompositeActor and try it again.
Also, my other pc doesn't
show up in the list - I have to add it manually. I know I'm doing
something wrong here, but what?
Where do I register slaves? The master-slave pdf mentions a registry
service, but how do I set it up? Also, how can I ensure that a
component is run distributed?
By default, each slave will not register itself. If you want to
enable slave registration, you need to change its configuration at
master-slave/resources/configurations/configuration.xml. Please change
the value of item 'registration->register' from 'false' to be 'true'.
If you have director in the DistributedCompositeActor, it will
ensure the actor will run distributed.
Oh, and when we're done with that - can I have multiple slaves on the
same host? This would be great, since it would allow me to run a cpu
bound task on each of my cores...
Since DistributedCompositeActor is based on Java RMI and each
machine can only have one hostname, I don't think you run multiple
slaves on the same host.

Daren Thomas
