Microgrid - The microthreaded many-core architecture

Traditional processors use the von Neumann execution model, some other processors in the past have used the dataflow execution model. A combination of von Neuman model and dataflow model is also tried in the past and the resultant model is referred as hybrid dataflow execution model. We describe a hybrid dataflow model known as the microthreading. It provides constructs for creation, synchronization and communication between threads in an intermediate language. The microthreading model is an abstract programming and machine model for many-core architecture. A particular instance of this model is named as the microthreaded architecture or the Microgrid. This architecture implements all the concurrency constructs of the microthreading model in the hardware with the management of these constructs in the hardware.Comment: 30 pages, 16 figure

An architecture and protocol for the management of resources in ubiquitous and heterogeneous systems based on the SVP model of concurrency

This paper proposes a novel hierarchical architecture and resource-management protocol for the delegation of work within a ubiquitous and heterogeneous environment. The protocol is based on serving an SVP place, where a component of work is delegated together with the responsibility for meeting any non-functional computational requirements such as deadline or throughput constraints. The protocol is based on a market where SANE processors bid for jobs to execute and selection is based on a cost model that reflects the energy required to meet the jobs requirements
