“…We compared the performance of rack to rack LIONS with other state-of-art rack to rack switches including the electrical switching network architecture employing flattened butterfly topology, the IBM-Corning's Optical Packet Switch for Supercomputers (OSMOSIS) and the Data Vortex optical switch [23]- [26]. Figures 12(a) and (b) show the effective bandwidth and the end-to-end latency of LI-ONS comparing with a flattened butterfly network under a 32-and 128-node for a message size of 128 bytes.…”

SUMMARYThis paper covers new architectures, technologies, and performance benchmarking together with prospects for high productivity and high performance computing enabled by photonics. The exponential and sustained increases in computing and data center needs are driving the demands for exascale computing in the future. Power-efficient and parallel computing with balanced system design is essential for reaching that goal as should support ∼billion total concurrencies and ∼billion core interconnections with ∼exabyte/second bisection bandwidth. Photonic interconnects offer a disruptive technology solution that fundamentally changes the computing architectural design considerations. Optics provide ultrahigh throughput, massive parallelism, minimal access latencies, and low power dissipation that remains independent of capacity and distance. In addition to the energy efficiency and many of the fundamental physical problems, optics will bring high productivity computing where programmers can ignore locality between billions of processors and memory where data resides. Repeaterless interconnection links across the entire computing system and all-to-all massively parallel interconnection switch will significantly transform not only the hardware aspects of computing but the way people program and harness the computing capability. This impacts programmability and productivity of computing. Benchmarking and optimization of the configuration of the computing system is very important. Practical and scalable deployment of photonic interconnected computing systems are likely to be aided by emergence of athermal silicon photonics and hybrid integration technologies.

Abstract:We demonstrate for the first time WDM multi-path routing through a monolithically integrated InP/InGaAsP 8 × 8 space and wavelength selective cross-connect. Data channels are dynamically routed from four input ports to the same output port with excellent OSNR from 27.0 to 31.1 dB. Representative data paths are evaluated in terms of optical power penalty. Data routing experiments are performed using round-robin scheduling with nanosecond time-scale switching times.

“…This can still reduce network delay and remove power-consuming optical-electronic-optical conversions (Masetti et www.intechopen.com al., 2003;Chiaroni et al, 2004). The SOA gate has provided the underlying switch element for the many of these demonstrators, leading to a new class of bufferless photonic switch which assumes (Shacham et al, 2005;Lin et al, 2005;Glick et al, 2005) or implements (Hemenway et al, 2004) buffering at the edge of the photonic network. Such approaches become more acceptable in short-reach computer networking where each connection already offers considerable buffering (McAuley, 2003).…”
