US Unveils World’s Most Powerful Supercomputer


Washington: US scientists have unveiled the world’s most powerful and smartest scientific supercomputer that can complete over 2,00,000 trillion calculations per second — providing unprecedented computing power for research in energy, advanced materials and artificial intelligence (AI).

The US Department of Energy’s Oak Ridge National Laboratory (ORNL) supercomputer called Summit will be eight times more powerful than its previous top-ranked system, Titan. For certain scientific applications, Summit will also be capable of more than 3 billion billion mixed precision calculations a second.

The IBM AC922 system consists of 4,608 compute servers, each containing two 22-core IBM Power9 processors and six NVIDIA Tesla V100 graphics processing unit accelerators, interconnected with dual-rail Mellanox EDR 100 Gb/s InfiniBand.

Summit also possesses over 10 petabytes of memory paired with fast, high-bandwidth pathways for data movement. The combination of cutting-edge hardware and robust data subsystems marks an evolution of the hybrid CPU-GPU architecture successfully pioneered by Titan in 2012.
