JAVAR - A prototype restructuring compiler for Java

JAVAR is a prototype Java restructuring compiler that can be used to make implicit parallelism in Java programs explicit by means of multi-threading. This prototype does not provide a complete Java front-end (for instance, unicode escapes are not supported and only some semantic analysis has been implemented) and relies completely on the identification of parallelism by means of annotations (automatic detection is not supported). Nevertheless, the compiler provides hopefully sufficient functionality to simplify the parallelization of Java programs. The tool can also generate HTML presentations of Java programs.

JAVAB - A prototype bytecode parallelization tool

JAVAB is a prototype bytecode tool that can automatically detect and exploit implicit loop parallelism in bytecode, i.e. the architectural neutral instructions of the JVM. Implicit parallelism is made explicit by means of the multi-threading mechanism provided by the JVM. Automatically exploiting implicit parallelism at bytecode level can be done independently from the source program and platform from which the bytecode was obtained, and independently from the platform on which the bytecode eventually will run. The parallelized bytecode remains architectural neutral and may exhibit speedup on any platform that supports the true parallel execution of JVM threads. Note that JAVAB has been incorporated in the Fortran-to-Java translator f2j (Dongarra and Seymour).
