Key: JBRULES-681
URL:

Project: Drools
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Components: drools-planner
Reporter: Geoffrey De Smet
Assignee: Geoffrey De Smet
Use Future's to spread all possible moves in each step over a number of threads.
This number of threads is equal to the number of cpu's by default, as no IO is done
during solving.
Problems:
- each thread will needs it own WorkingMemory and during a step, each working memory will
need to be updated
- a bunch of classes will need to be thread safe, or at least visibility save, such as
bestsolutionrecaller.
- Barriers will be needed to collect the result of each step
- decks might be a great way to spread out the load
