This is an excellent question, and one that I've looked at more than
once. Someday I may well provide an implementation of this. There are
implementation difficulties having to do with fine-grained
synchronization (the Rete network is not a proper tree, and separate
paths can converge downstream,) but nothing insurmountable.
Trial implementations I've done in the past showed negative speedup
factors, largely because thread synchronization wasn't cheap. I think
matters have improved with today's JVMs, so perhaps it's time to
revisit the idea. I do, in fact, work on a dual-processor machine myself.
