Express lanes modification to the data vortex photonic all-optical path interconnection network

Bozek, Matthew Peter 19 May 2008 (has links)
Today s supercomputers require interconnection networks with high bandwidth and low latency to exploit parallelism. The data vortex is an all optical path interconnection network defined and then proven to achieve high level of message acceptance and low levels of message latency. In this thesis research, three enhancements to the data vortex are defined and tested for performance. They are compared to an unmodified data vortex using the average latency and offered traffic acceptance rates as metrics. Minimal angle counts are established where express lane enhancements are established. An express lane enhancement allows exploitation of locality yielding an 8% to 12 % reduction in average latency and a 4% to 6% increase in message acceptance. Semi-Express lanes cannot effectively exploit locality but still yield a 20% increase in message acceptance and a 4% decrease in average latency. Express outputs can exploit locality for a 28% to 32% increase in message acceptance and 12% to 15% decrease in average latency.
