Fast-Reconfigurable Optical Networks for Data-Intensive Computing

SESSION: Emerging Technologies Exhibits

EVENT TYPE: HPC Impact Showcase & Emerging Technologies

TIME: 7:00PM - 9:00PM

ROOM:Show Floor - 233 Exhibits

ABSTRACT:

Data-intensive computing increasingly involves operations at the scale of an entire system, requiring quick and efficient processing of massive datasets. We present a network architecture, comprised of optical-switch and burst-mode transceiver technology, designed to support demanding graph algorithms in distributed-memory systems. The fabric is designed to deliver up to 10 terabytes per second of node bandwidth and predictable performance under heavy load with latencies under a microsecond. This vision for a unique optical switch provides a path to overcoming the limitations of electrical switch networks. To make this a reality, we are developing nanosecond-scale photonic switches and low-power 25-Gb/s WDM transceivers with burst-mode clock and data recovery for link retraining in tens of nanoseconds. Network simulations predict graph performance on par with today’s leading supercomputers, and orders of magnitude improvement in power efficiency and footprint would allow the system to fit within a few racks.
