Has anyone had any experience with using an Object-Oriented Programming Language in a distributed processor environment? We are currently developing a product in which there may be up to 36 processors, all of which are peers; objects on all processors are part of the same object universe. When we began a couple of years ago, there was no OOPL support for anything like this, so we "rolled our own" using C. We wrote a router that shuttles messages and replies between objects (regardless of the processor), and a database that coordinates transactions over multiple processors. Since then, we've been trying to keep abreast of developments in this area. In particular, we would like to be able to use a real OOPL so that we would have better support of inheritance (as it stands, classes are supported only administratively.) The mainstream languages still assume that your application will be compiled as a program on one processor, but I'm hoping to get pointers to language extensions or special techniques that allow us to extend this.

I know from a course I just finished from North Carolona State University that Hank Levy at the Univeristy of Washington has done a considerable amount of work over the past few years on Distributed and Parallel object-oriented systems. You might want to try a literature search for hist name or the names of the systems, "Emerald" and "amber'.
