In this paper, we propose a new router architecture that supports wormhole switching and circuit switching concurrently. This architecture has been de- signed to take advantage of temporal communication loc- ality. This can be done by establishing a circuit between nodes that are going to communicate frequently. Messages using those circuits face no contention. By combining cir- cuit switching, pre-established physical circuits and wav e pipelining across channels and switches, it is possible to increase network bandwidth considerably, also reducing latency for communications that use pre-established phys- ical circuits. This router architecture also allows to redu ce the overhead of the software messaging layer in multicom- puters by offering a better hardware support. Preliminary performance evaluation results show a drastic reduction in latency and increment in throughput when messages are long enough, even if circuits are established for a single transmission and locality is not exploited. |
