That’s right, America once again has the most powerful supercomputer in the world, for now, which is eight times more powerful than the Titan supercomputer. Capable of peak performances of 200 petaflops or 200,000 trillion calculations per second, the Summit supercomputer owned by the U.S. Department of Energy is used for scientific purposes. Summit is, in fact, an IBM AC922 supercomputer that features a total of 4,608 compute servers containing no less than six Nvidia Tesla V100 GPUs and two 22-core IBM Power9 processors. Summit’s 4,608 compute servers are interconnected using dual-rail Mellanox EDR 100Gb/s InfiniBand and uses 10 petabytes of RAM (system memory) that’s paired with high-bandwidth, efficient, and fast pathways.
