The Summit and Sierra supercomputers at Oak Ridge National Lab held onto the first and second place slots in the latest list of the top 500 supercomputers in the world. The 53rd edition of list also represents the first time all 500 machines deliver a petaflop or more on the performance benchmark.
China has 219 TOP500 systems, making up 43.8% of all systems listed. Although the U.S. trails with 116 — near the all-time low – the size of those systems kept the U.S. close to China in terms of installed performance.
In a May 2018 blog post, Energy Secretary Rick Perry acknowledged the U.S. has slipped in the rankings of the world’s fastest machines, but reiterated the administration’s commitment to expanding the use of exascale systems. See the TOP500 list here.
Other recent news in high-performance computing includes:
Exabyte storage. Oak Ridge National Laboratory and Cray Inc. announced development of a first-of-a-kind exabyte storage solution for the lab’s Frontier exascale supercomputer, being built on Cray’s Shasta architecture.
The storage solution will include over 1 exabyte of hybrid flash and high-capacity storage so that diverse modeling, simulation analytics and artificial intelligence workloads can run and scale simultaneously. The storage will be directly connected to Frontier by the company’s Slingshot high-speed network, eliminating the need for storage routers and lowering cost, complexity and latency.
The Frontier system is anticipated to debut in 2021 as the world’s most powerful computer with a performance of greater than 1.5 exaflops. Read more here.
