Abstract: JavaPIE extends the research on parallel programming environment through Internet,aiming to become more portable, open and sharable. Supported by the functions of parallel programming environment（ParaPIE, PEFPT, etc.） and automatic parallelizing compilers（AFT, Agassiz, etc.）, the interactive tools implemented in Java integrate the parallelizing compiling methods, program semantics analytic techniques, interactive information visualizing tools, and testing scenario documents into a coherent web info site accessible in the Internet. The perspective of internationally cooperative research is coming closer to us. Here discussed are the implementation and application of the JavaPIE prototypes.
