The Oak Ridge National Laboratory’s ORNL Frontier supercomputer has achieved a new world record by breaking the Exaflop barrier at 1.102 exaflop/s. It is based on the HPE Cray EX235a architecture and features third-gen AMD EPYC 64C 2 GHz processors and AMD Instinct 250X GPUs. The system has a total of 8,730,112 cores and utilizes AMD’s Infinity Fabric for the CPU-GPU interconnect. Its power efficiency is rated at 52.23 gigaflops per watt.

Exascale is the next level of computing performance. By solving calculations five times faster than today’s top supercomputers—exceeding a quintillion, or 1018, calculations per second—exascale systems will enable scientists to develop new technologies for energy, medicine, and materials. The Oak Ridge Leadership Computing Facility will be home to one of America’s first exascale systems, Frontier, which will help guide researchers to new discoveries at exascale.

As a child of the 70’s I was part of the many who became enthralled by the video arcade invasion of the 1980’s. Saving money from various odd jobs I purchased my first computer from a friend of my...


  1. "What do the Oak Ridge Boys have to do with Supercomputers?"

    -- my son, Age 15.

    ** I was shocked he knew the ORB, but I guess his grandparents listen to that era music a lot
