Outline of Final Research Achievements |
We have proposed and evaluated interconnects technology for exascale HPC computers in order to provide (1) 1us communication latency to a farthest node and (2) multiple-times improvement of power efficiency when compared to existing electric-switched networks. Our technology relies on optical wavelength division multiplexing switches using random shortcut links. Using the optical switches efficiently provides inter-rack cabling that minimizes the total length of wires. We take a suitable network topology for a given traffic patterns by using the small-world phenomenon on our proposed interconnection networks.
