Abstract: A method and apparatus for producer graph oriented programming and execution. According to one aspect of the invention, a runtime is provided that interprets producer dependency declarations for methods. The producer dependency declarations identify at run time a set of zero or more producers, where a producer is a runtime instantiatable construct that includes at least an instance and a method associated with that instance. The runtime automatically generates and executes, responsive to receiving a designation of a producer of interest whose method has a producer dependency declaration, a producer graph. The producer graph initially includes the producer of interest and is generated, from the producer of interest to source producers, through instantiation of producers based on the producer dependency declarations of the methods of the producers already in the producer graph. The runtime sequences the execution of the producers in the producer graph as indicated by the producer graph.

Abstract: Embodiments of parallelization and/or instrumentation in a producer graph oriented programming framework have been presented. In one embodiment, a request to run an application program is received, wherein object-oriented source code of the application program includes methods and producer dependency declarations, wherein the producer dependency declaration for a given method identifies a set of zero or more producers with outputs that are an input to the given method, wherein a producer is at least an instance and a method associated with that instance. Further, execution of the application program may be parallelized based on dependency between producers of the application program using the runtime. In some embodiments, the application program is instrumented using the runtime.

Abstract: Embodiments of a producer graph oriented programming framework with scenario support have been presented. In one embodiment, a request to evaluate potential impacts by a change on an application program is received. The application program includes a set of producers, each having at least an instance and a method associated with the instance. Responsive to the request, the application program may be simulated with the change while the existing states and existing outputs of the producers are preserved.

Abstract: Graph oriented programming and execution. According to one embodiment of the invention, execution of a program includes automatically discovering and building a graph. The graph is to represent parent child relationships between combinations. Each combination is a specific method and a specific object-oriented instance. Based on a first of the combinations, other combinations are determined by iteratively discovering the child combinations for already discovered parent combinations. The graph is built of nodes coupled with links. Each of the plurality of combinations is identified by one of the nodes. Each of the parent child relationships is represented by one of the links. Execution of the program also includes executing the graph in an order indicated by the links until the root node is reached. Execution of each of the parent nodes includes executing the combination identified by that parent node to generate an output using the outputs of its child node(s).
