Abstract: One embodiment includes a method of performing dataflow processing. The method includes representing a first asynchronous processing node as a first future. The first future represents the lifecycle of processing of the first asynchronous processing node. The method further includes representing one or more other asynchronous operations as one or more other futures. The one or more other futures represent the asynchronous completion of one or more operations'processing. The first future and the one or more other futures are represented as a single composite future. The single composite future represents completion of processing of the combination of the first asynchronous processing node and the one or more other asynchronous operations.

Abstract: Processing messages in dataflow networks. The method includes, at a first entity, receiving from a second entity a first offer of a first message to process. The method further includes determining to not process the first message. As a result of determining to not process the first message, such an indication is made to the second entity. Further as a result of determining to not process the first message, an indication is stored that the second entity offered a message. The indication includes an indicator correlated to the second entity. Subsequent to indicating to the second entity, using the indication the method includes indicating to the second entity availability to process a message.

Abstract: Systems and methods are provided for selecting parameter values and combinations of parameter values to use in connection with testing. A graphical user interface allows a user to graphically illustrate the importance of parameter values by drawing a probability curve for each parameter. The resulting curves are then converted to mathematical functions that are then combined into a combination function. The combination function is then evaluated for different parameter value combinations. The parameter value combinations that cause the combination function to exceed a predetermined probability value are selected for testing.
