摘要： Processing a dataflow program by a program development tool includes detecting a pair of actors defined by dataflow program instructions, wherein the pair of actors include a producer actor and a consumer actor, the producer actor supplying a data structure to the consumer actor via a path that comprises at least one connection and possibly also intervening other actors. An analysis is performed including analyzing one or more operations of the producer actor that involve the data structure and/or analyzing one or more operations of the consumer actor that involve the data structure. A result of the analysis is used as a basis for selecting a minimal amount of information from among a plurality of data handling possibilities concerning the data structure. A transformed program is produced in which the selected minimal amount of information is caused to be passed from the producer actor to the consumer actor.

摘要： Processing a dataflow program by a program development tool includes analyzing an actor defined by the dataflow program to identify original sequences of actions that can be reformulated to achieve greater execution parallelism while maintaining the same functionality as the original sequences. A processed dataflow program is produced comprising processed dataflow program instructions and decision point program instructions. The processed dataflow program instructions comprise alternative sequences of reformulated actions that achieve greater execution parallelism while maintaining the same functionality as the identified one or more original sequences. The decision point program instructions direct processing equipment to select and execute one or more of the alternative sequences of reformulated actions, wherein selection is based on state and token information in existence at the time of selection. When more than one alternative sequence can be selected, selection of sequence with highest parallelism is preferred.
