Abstract :
A crucial part of any high-performance computing (HPC) system is its interconnection network. Corning and IBM are jointly developing a demonstration interconnect based on optical cell switching with electronic control. The Corning-IBM joint optical shared memory supercomputer interconnect system (Osmosis) project explores the opportunity to advance the role of optical-switching technologies in such systems. Key innovations in the scheduler architecture directly address the main HPC requirements: low latency, high throughput, efficient multicast support, and high reliability
