A Progress in Developing High-performance Multiprocessor Network Routers based on Optoelectronic Technologies

Computer architects have realized that interconnection bandwidth has become a critical limitation to the development of highperformance multiprocessor systems. Major reason is that the progress of processor performance has increasingly outpaced that of the interconnection networks, thereby limiting the usefulness of multiprocessor systems. This work presents a comprehensive study and the development of optoelectronic-based network routers. Optoelectronic technology can potentially provide ample bandwidth required by multiprocessor systems but at the same time can raise some critical issues that are discussed here such as on-chip wiring and chip packaging. We also proposed new architectural techniques suitable for the development of optoelectronic-based network routers to increase the network bandwidth utilization.
