    Emerald:  An Object-Based Language for Distributed Programming

    Despite the existence of many distributed systems,
    programming distributed applications is still a complex task.
    We have designed a new object-based language called Emerald
    to simplify distributed programming.  The novel features of
    Emerald include (1) a single object model used for
    programming both small local objects and large distributed
    objects, (2) support for abstract types, and (3) an explicit
    notion of location and mobility.  While local and remote
    Emerald objects are semantically identical, the compiler is
    able to select from several implementation styles;  Emerald
    provides performance commensurate with procedural languages
    in the local case and with remote procedure call systems in
    the remote case.  The Emerald system has been prototyped on a
    small local area network of MicroVAX IIs running Ultrix. 
    
    This talk will give an overview of the Emerald project and
    the design of the Emerald language and run-time kernel.
