Orca: A Language for Parallel Programming of Distributed Systems
Orca is a language for implementing parallel applications on loosely coupled distri-buted systems. Unlike most languages for distributed programming, it allows processes on different machines to share data. Such data are encapsulated in data-objects, which are instances of user-defined abstract data...
