A hybrid open queuing network model approach for multi-threaded dataflow architecture

Abstract : Multi-threading has been proposed as an execution model for massively built parallel processors. Due to the large amount of potential parallelism, resource management is a critical issue in multi-threaded architecture. The challenge of multi-threading is to hide the latency by switching among a set of ready threads and thus to improve the processor utilization. Threads are dynamically scheduled to execute based on availability of data. In this paper, two hybrid open queuing network models are proposed. Two sets of processors: synchronization processors and execution processors exist. Each processor is modeled as a server serving a single-queue or multiple-servers serving a single-queue. Performance measures like response times, system throughput and average queue lengths are evaluated for both the hybrid models. The utilizations of the two models are derived and compared with each other. A mean value analysis is performed and different performance measures are plotted.
