Abstract
In this paper we discuss some experiences with javar, which is a prototype Java restructuring compiler that supports the automatic conversion of serial loops into constructs that use the multi-threading mechanism of the language to exploit any parallelism in these loops. Expressing parallelism in Java itself clearly has the advantage that the transformed program remains portable. After compilation of the transformed Java program into bytecode, speedup can be obtained on any platform on which the Java Virtual Machine implementation supports the true parallel execution of threads, whereas we will see that the threads only induce a slight overhead on uni-processors.KeywordsWavelet TransformationJava ProgramParallel ExecutionLoop IndexJava Virtual MachineThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
