Multi-threaded Solver: construction heuristics, local search, ... ------------------------------------------------------------------ Key: JBRULES-681 URL: https://issues.jboss.org/browse/JBRULES-681 Project: Drools Issue Type: Feature Request Security Level: Public(Everyone can see) Components: drools-planner Reporter: Geoffrey De Smet Assignee: Geoffrey De Smet Priority: Critical 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
