The tutorials on OO that I've read generally don't address parallel or distributed OO work, except for the SmallTalk doccos which specifically say that OO (or at least their OO) doesn't help with concurrent programming. Has there been any work in using OO messaging as the basis for distributed programming? How far has this topic progressed? Are there any designs publicly available for research purposes? For network software? For parallel computing? Has anyone cooked up an RPC-like system where you specify an asychronous (RPC is synchronous) OO messaging protocol and it generates software stubs for you to fill in? Are there any debuggers available?

There has been a *lot* of work on concurrent OO programing and
languages. I would suggest that you look into:
Gul Agha's work with Actors (sorry no reference handy)
Andrew Chien's PhD thesis from MIT (finished this year, I think in June),
"Object-oriented concurrent programming" edited by Akinori Yonezawa
and Mario Tokoro. from MIT Press, c1987 ocm14-719682.
These all fall into a single "school" of approaches to OO concurrency,
since they all (more or less) derive from the Actor model proposed by
Agha. I would be interested to hear about any other separate schools
of thought that someone may have a reference to.
Of course, a perusal of recent OOPSLA and ECOOP proceedings would
probably turn up a few...

Are there any debuggers available? How about "ACTORS: A Model for Distributed Applications..." The title is something like that, someone may want to follow up with the ISBN, etc... I remember glancing at the book...it is largely based on mail-queueing etc... Again, someone may want to follow up with details. --- Robert D. Thompson rdthomps@vela.acs.oakland.edu

Are there any debuggers available? Sigplan 24(4) April 89 is an excellent survey of what's going on, and (real soon now) the proceedings of this year's Object-Based Concurrent Programming Workshop at OOPSLA will be in a Sigplan special issue. Some of the best papers were also published in OOPSLA itself. Also there are a few books from the MIT Press. Look for the names of editors Yonezewa and/or Tokoro.
