Networking for Exascale Science
The Department of Energy’s Energy Sciences Network (ESnet) participated in developing the final findings and recommendations for DOE’s exascale requirements synthesis report as part of the exascale requirements reviews held with DOE program offices.
To support the increased flow and size of research data sets, ESnet and NERSC built a 400 gigabit-per-second (Gbps) super-channel, the first-ever 400G production link to be deployed by a national research and education network. DOE research is increasingly data-driven as scientists generate massive datasets at experimental facilities and through modeling and simulation at supercomputing centers like NERSC. Having higher-speed networks in place ahead of the growth in data sets will allow researchers to be able to move and analyze data on next generation supercomputers.
