RMI cluster management tools

Question

Hello,
My application requires managing a bunch of RMI server processes running on several linux machines (about 5 to a machine).
This application "broker" inputs jobs from an external source (web server) and then delegates each job to the appropriate RMI server process based on a mapping name.
Most of code is simple grunt admin work like starting the processes on each machine, checking their condition at some frequency, keeping track of processes that are in use or available, shutting down processes, etc.
I suspect what I'm trying to do has been done before (many times), so I'm looking for a some suggestions on pre-existing projects/libraries are good for doing this type of thing.
My requirements:
* Linux
* Java API

Answer 1

Thanks for the response.
What I'm after is a framework to handle launching processes, monitoring them, and shutting them down - boring admin work and not so much job scheduling.
I can't use the model where delegates ask for work because of the large amount of persistent state between jobs. I would have to serialize between every job, which would take a long time (jobs are short, serialization long).
So, in my scenario, the consumer app is bound to a specific process for the life of the session.
