Selective Broadcasting for Reconfigurable Optical Interconnects in DSM systems
نویسنده
چکیده
Recent developments of coarse WDM optoelectronic components will allow for the fabrication of low cost, high-speed reconfigurable interconnection networks within large distributed sharedmemory (DSM) multiprocessor machines, by using the wavelength tunability in combination with a broadcast-and-select mechanism. We discuss in this work the advantages and the limitations they impose on network performance through detailed simulations of benchmark executions. We furthermore propose a passive selective broadcasting element which allows to scale the reconfiguration scheme to larger DSM multiprocessor networks with the proposed coarse WDM devices that have typically low channel counts.

Performance of large-scale reconfigurable optical interconnection networks in DSM systems
We present how a custom reconfigurable optical network can be incorporated into Distributed Shared-memory (DSM) multiprocessor machines, and show the potential speed improvement of the interprocessor communication, even when the limits associated to opto-electronics are included. We find that for 32 processors connected in a torus topology, slowly reconfiguring interconnects can provide up to 3...
