Many emerging information processing applications require applying various fork and join type operations such as correlation, aggregation, and encoding/decoding to data streams in real-time. Each operation will require one or more simultaneous input data streams and produce one or more output streams, where the processing may shrink or expand the data rates upon completion. Multiple tasks can be co-located on the same server and compete for limited resources. Effective in-network processing and resource management in a distributed heterogeneous environment is critical to achieving better scalability and provision of quality of service. In this paper, the authors study the distributed resource allocation problem for a synchronous fork and join processing network, with the goal of achieving the maximum total utility of output streams.
