We address the problem of how to exploit optics for ultrascale High Performance Computing interconnect fabrics. We show that for high port counts these fabrics require multistage topologies regardless of whether electronic or optical switch components are used. Also, per stage electronic buffers remain indispensable for maintaining throughput, lossless-ness(More)
— A crucial part of any high-performance computing system is its interconnection network. In the OSMOSIS project, Corning and IBM are jointly developing a demonstrator interconnect based on optical cell switching with electronic control. Starting from the core set of requirements, we present the system design rationale and show how it impacts the practical(More)
– The OSMOSIS project explores the role of optics in large-scale interconnection networks for high-performance computing (HPC) systems. Its main objectives are solving the technical challenges to meet the stringent HPC requirements of high bandwidth, low latency, low error rates, and cost-effective scalability. We discuss the technologies and architectural(More)
Availing security in a wireless sensor network requires more than user authentication with passwords or digital certificates and confidentiality in data transmission. The openness of wireless sensor network model makes it vulnerable and prone to sophisticated intrusion attacks like Denial of Service (DDOS) and side channel attacks. To handle large scale(More)
