| Research Abstract |
We designed a virtual distributed system for an object-oriented concurrent language ABCL/1 which consists of the virtual front-end processor and a pool of virtual node processors. Each object is implemented as a virtual stack machine which is executed on a virtual node processor. The language processor translate source code into the virtual stack machine code. Also, a noble distributed garbage collection scheme is presented which is used in our implementation. The scheme employs the Distributed Snapshot technique. A debugging method for Concurrent Object-Oriented Systems is developed. Our method is based upon a new notion called Object Groups. An Object Group is a collection of objects which forms a natural unit for performing collective tasks. The language constructs which specify and use Object Groups have been introduced into an object-oriented concurrent language ABCL/1.
