[Lisa-users] Progress report

[David E. Y. <yo...@nc...>]

Greetings. As of today, I consider LISA to be MP-safe to a reasonable
degree. It is now possible to run multiple inference engines within a
single Lisp world (with each engine, perhaps, assigned to a unique
process); it is also possible for multiple threads to interact with a
single inference engine. I'm going to write a sample application that
will both test and illustrate the MP capabilities; this will be
included in the LISA distribution.

Clearly, those Lisp implementations that don't support MP will not
benefit from these new features. However, such platforms will still be
able to employ LISA in single-threaded mode.

Also, after some discussion on c.l.l I've refined the instance
synchronization protocol such that there is less of a burden on the
application developer (i.e. LISA user).

It's now time to think about a beta release. Before I do this I want
to write some usable documentation that will both help folks
unfamiliar with either CLIPS or Jess and highlight some of LISA's more
interesting features.

Currently, it looks like I'll have a beta ready within the next three
weeks. I'll keep the group apprised.

Regards,
