Abstract: Methods and systems for executing an application data flow graph using a network of computational nodes are disclosed. In specific examples, the network of computational nodes can be a network-on-chip for a multicore processor. One method includes transitioning first application data from a first source computational node to an intermediary computational node. The method can also include providing second application data, from a computation layer of the network of computational nodes, on the intermediary computational node. The method can also include multicasting the first application data in combination with the second application data from the intermediary computational node to at least two destination computational nodes. The first source computational node, the intermediary computational node, and the at least two destination computational nodes are all in the network of computational nodes.

Abstract: Methods and systems for executing an application data flow graph on a set of computational nodes are disclosed. The computational nodes can each include a programmable controller from a set of programmable controllers, a memory from a set of memories, a network interface unit from a set of network interface units, and an endpoint from a set of endpoints. A disclosed method comprises configuring the programmable controllers with instructions. The method also comprises independently and asynchronously executing the instructions using the set of programmable controllers in response to a set of events exchanged between the programmable controllers themselves, between the programmable controllers and the network interface units, and between the programmable controllers and the set of endpoints. The method also comprises transitioning data in the set of memories on the computational nodes in accordance with the application data flow graph and in response to the execution of the instructions.
