1119-1120, Seoul Korea, Aug. 1999. Proceedings of Optics in Computing 2000, pp. Optical interconnection in the massively parallel computer Massively parallel computers require an extremely high throughput and highly flexible inter-node connection. Each motherboard is equipped with four nodes and also has four input ports and four output ports. It therefore becomes more practical to build powerful systems with a huge number of nodes.
Optical interconnection allows low-power data transmission over a long distance.
Elimination of the connector and cable bottlenecks Optical interconnection allows us to use lightweight fiber cables and compact connectors. It also decreases the mounting area required. The skew of the rising time and falling time at the receiver port of the SU is suppressed to within 650 to -380 ps. The optical interconnection offers sufficient reliability and is feasible for a practical computer system. Our parallel optical interconnection is also applicable to computer systems and will help to overcome the communication bottlenecks in such systems.
