Today the United States Department of Energy and Oak Ridge National Labs just announced its new Summit supercomputer. The new supercomputer reaches over 200 petaflops of performance. For AI operations, the new ORNL Summit supercomputer hits 3.3 exaops of performance. To give a perspective on that number, Jensen Huang, CEO of NVIDIA, said that ?the universe is only half an exa seconds old.? He also went on to say that Summit is able to simulate a human brain where each of the brain?s 100 billion neurons is modeled with 30 million instructions per second.
ORNL Summit is comprised of the IBM AC922 system. There are 4608x dual 22 core IBM Power9 compute nodes, each containing two 22 core IBM Power9 CPUs and six NVIDIA Tesla V100 GPUs. In supercomputers, the interconnect is extremely important and Summit uses dual-rail Mellanox EDR 100Gb/s InfiniBand. A key innovation is that the system utilizes PCIe 4.0 which is twice as fast as the common PCIe 3.0 found in today?s mainstream servers and desktops. The new Summit supercomputer has over 10PB of memory.
