The Extensible Java Preprocessor Kit and a Tiny Data-Parallel Java

We describe the extensible Java preprocessor EPP and a data-parallel extension of Java implemented with EPP. EPP can be extended by incorporating EPP plugins. These plugins are programmed with the Ld-2 language that we also describe. Tiny Data-Parallel Java is an example of EPP plugin. High portability is guaranteed because the translated code and the run-time systems are pure Java code. Applications can be executed in parallel if the VM interpreter supports parallel execution of Java threads. We provide a preliminary performance evaluation of this system.
