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 develop-ing, running and managing parallel, distributed and mobile Java applications. It incorporates features like object mi-gration, asynchronous method invocation and remote class loading while providing an easy-to-use interface. Addi-tionally, Babylon v2.0 enables Java applications to seam-lessly create and interact with remote objects while protect-ing 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 po-tential cluster computing benefits of the system are demon-strated with experimental results which show that sequen-tial Java applications can achieve significant performance benefits from using Babylon v2.0 to parallelize their work across a cluster of workstations.
