DJMix: A distributed Java']Java bytecode specialization system

With the development of internet technology, neutral programming languages such as Java play more and more important roles in developing software running on heterogeneous architectures and on distributed systems. In other words, user can write generic programs firstly, and then specialize to ones would run on specific platforms efficiently. In this paper, we present a mechanism to support what so called, write once and run anywhere, efficiently. The mechanism is based on Partial Evaluation, which is a technique to partially execute a program when some of its input data are available. That is, we can use Partial Evaluation to optimize a generic program when platform is known. Based on Java bytecode partial evaluator Jmix, this paper proposes a distributed version, called DJMix. The results show that DJMix can be used to specialize distributed Java bytecode programs, especially those using RMI.
