....architecture for distribution of predicates and reactors for parallel computation and several concurrency control models that go with the architecture. 1 1 Introduction Open Constraint Programming [4] proposed by Jaffar and Yap from NUS in 1998 and augmented with a reactive database calculus [5] by Jaffar, Wong and Yap in 2000, is a new model for high level concurrent reactive programming. It is designed for programs that react to internal or external events and 1 This paper documents author s rudimentary proposal of Distributed OCP as part of his PhD project. 1 manipulate shared ....

....portfolio management application, we can envisage tens of thousands of users sending multiple reactors to the OCP server at the same time. Each of these reactors requires computation cycles and memory allocation in general and they are considered long lived transactions in the database terms [5]. Therefore it is compelling to introduce parallelism to the implementation of OCP. The main idea is to distribute data and distribute computation. It is assumed that most reactors require private predicates and don t interact with others very often, therefore part or whole of the logic program ....
