Providing structure for medium-grained distributed object-based computation

Abstract

Pipelined Processor Farms (PPF) are a generic parallel processing structure suitable for continuous flow, multi algorithm applications. PPF has been redesigned for a multimedia workload which is multifunctional and multimodal. A dynamic object based processing structure is implemented which will map onto mobile stations. The PPF processing model with asynchronous message passing in a multi threaded environment is in effect a version of the actor paradigm which is a dynamic form of encapsulated system. Stable software facilities for distributed object based systems which may include reflection are also needed. The supportive facilities of Java remote method invocation (RMI) are currently being used by PPF. PPF and RMI have been wedded together in a software toolkit, providing a development environment which includes performance prediction, analysis, and guided code generation.
