Babylon v2.0: middleware for distributed, parallel, and mobile Java applications

Babylon v2.0 is a collection of tools and services that provide a 100% Java compatible environment for developing, running and managing parallel, distributed and mobile Java applications. It incorporates features like object migration, asynchronous method invocation and remote class loading while providing an easy-to-use interface. Additionally, Babylon v2.0 enables Java applications to seamlessly create and interact with remote objects while protecting those objects from other applications by implementing access restrictions and separate name spaces. This paper describes the most important programming features of the Babylon v2.0 system, using a heat diffusion example to show how they are used in practice. The potential cluster computing benefits of the system are demonstrated with experimental results which show that sequential Java applications can achieve significant performance benefits from using Babylon v2.0 to parallelize their work across a cluster of workstations
