An Energy Efficient Flexibly Interconnected Photonic Data Center Architecture for Extreme Scalability

The cost and complexity of existing interconnects prevent designing datacenter racks tailored to emerging applications such as machine learning. The PINE interconnect (Photonically Interconnected datacenter Elements) allows compute, memory or storage modules to be flexibly combined through one-model-fits-all embedded photonic connectivity and better utilize distant resources. In addition, PINE allows system-level bandwidth to be reconfigured to better match application demands via bandwidth steering.

About Berkeley Lab

Founded in 1931 on the belief that the biggest scientific challenges are best addressed by teams, Lawrence Berkeley National Laboratory and its scientists have been recognized with 16 Nobel Prizes. Today, Berkeley Lab researchers develop sustainable energy and environmental solutions, create useful new materials, advance the frontiers of computing, and probe the mysteries of life, matter, and the universe. Scientists from around the world rely on the Lab’s facilities for their own discovery science. Berkeley Lab is a multiprogram national laboratory, managed by the University of California for the U.S. Department of Energy’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit
