Data parallel programming in the ParJava system

We present а general description of the ParJava environment being an extension of the Java environment by software tools for development of scalable efficient portable object-oriented parallel programs for homogeneous and heterogeneous parallel computing systems with distributed memory. The development support system used for programming of parallel applications can use a homogeneous or heterogeneous computer network. The environment under consideration allows us to apply algorithms, designed for homogeneous systems, to construct programs for heterogeneous systems without loss of scalability (i.e., the applications become portable). We present here a Java-class library providing low-level tools that support the development, implementation and execution of SPMD-programs for homogeneous and heterogeneous computer networks. These software tools can be used as a basis for implementing object models of higher-level parallel programming.
