------------------------------------------------------------
Do you mean spread tasks as many as possible to all GroomServers?
For example, a job having 5 tasks will have tasks spread to 5 GroomServers
(each GroomServer ideally receive a task for computation)?
If that's the case, the current refactoring code might be able to offer similar
mechanism. In that GroomServer will ask for task assign, so ideally tasks
should be able to spread to GroomServer as many as possible; in real scenario
some (fast) GroomServers may be assigned several tasks that belongs to the same
job.
