It's still on my mind and in the roadmap: https://issues.jboss.org/browse/PLANNER-76 Other issues have currently taken priority (due to customer requests etc). http://www.optaplanner.org/download/releaseNotes/releaseNotes6.1.html In 6.1 (CR1 is being build right now), more preparation for this is in place: everything is now on the selector architecture.
The technical challenge is still the same: don't break incremental score calculation while parallelizing OptaPlanner, because incremental score calculation is a far bigger speedup than anything parallelization can bring to the table. The technical design that adheres to this is still the same (last comment on PLANNER-76): Use surrogate entity id's, to allow migrating Move's from 1 workingSolution to another. > > I'm contemplating doing some investigating of my own to attempt to leverage > additional hardware in a distributed way for our application.

Any experiments you do would be interesting for me to observe. Especially if it's user-domain agnostic, I am interested to merge a PR adding this functionality. > > Any insight you could share? Parallelize the method LocalSearchDecider.pickNextStep() :) Replace the LocalSearchDecider instance in DefaultLocalSearchPhase with your own.
