Abstract

The next milestone objective of HPC is exascale computing, which includes millions of nodes in the system. One of the key critical barrier toward realizing exascale computing is the fundamental challenge of communication networks. We propose a high performance optical interconnect architecture based on Arrayed waveguide grating router (AWGR) with WDM wavelength routing, the inherent parallelism in AWGRs and multi-hop switching provide high scalability of the network. Theoretical analysis and simulation show its better performance compared with fat-tree architecture.
