Artificial intelligence complements the abilities and reinforces human talent. Coined in 1955 to describe a new computer science sub-discipline, “Artificial Intelligence” today includes a variety of technologies and tools, some time-tested, others relatively new. IDC estimated that the AI market will grow from $8 billion in 2016 to more than $47 billion in 2020.
Supercomputers today have already turbocharged some AI applications. Let’s take a brief look at the AI-powered smartest machines on Earth.
IBM WATSON
With a brain size of 2,400 home computers and a database of 10 million documents; augmented by AI, IBM Watson supercomputer is dubiously yet famously predicted massive takeover of all time.
The Watson supercomputer processes at a rate of 80 teraflops (trillion floating point operations per second). To replicate (or surpass) a high-functioning human’s ability to answer questions, Watson accesses 90 servers with a combined data store of over 200 million pages of information, which it processes against six million logic rules.
SUMMIT
Summit or OLCF-4 is a supercomputer developed by IBM for use at Oak Ridge National Laboratory, which as of November 2018 was the fastest supercomputer in the world, capable of 200 petaflops. Its current LINPACK is clocked at 148.6 petaflops. As of November 2018, the supercomputer is also the 3rd most energy-efficient in the world with a measured power efficiency of 14.668 GFlops/watt. Summit is the first supercomputer to reach exaop (a quintillion operations per second) speed, achieving 1.88 exaops during a genomic analysis and is expected to reach 3.3 exaops using mixed precision calculations.
SIERRA
Sierra or ATS-2 is a supercomputer built for the Lawrence Livermore National Laboratory for use by the National Nuclear Security Administration as the second Advanced Technology System. It is primarily used for predictive applications in stockpile stewardship, helping to assure the safety, reliability and effectiveness of the United States’ nuclear weapons.
Sierra is very similar in architecture to the Summit supercomputer built for the Oak Ridge National Laboratory. The Sierra system uses IBM POWER9 CPUs in conjunction with Nvidia Tesla V100 GPUs. The nodes in Sierra are Witherspoon S922LC, IBM POWER9 22C 3.1GHz, NVIDIA Volta GV100 OpenPOWER servers with two GPUs per CPU and four GPUs per node. These nodes are connected with Dual-rail Mellanox EDR InfiniBand with 1.57 million cores and 94.64 petaflops.
SUNWAY TAIHULIGHT
The Sunway TaihuLight (Chinese: 神威·太湖之光, Shénwēi·tàihú zhī guāng) is a Chinese supercomputer which, as of November 2018, is ranked third in the TOP500 list, with a LINPACK benchmark rating of 93 petaflops. The name is translated as divine power, the light of Taihu Lake. This is nearly three times as fast as the previous Tianhe-2, which ran at 34 petaflops. As of June 2017, it is ranked as the 16th most energy-efficient supercomputer in the Green500, with an efficiency of 6.051 GFlops/watt. It was designed by the National Research Center of Parallel Computer Engineering & Technology (NRCPC) and is located at the National Supercomputing Center in Wuxi in the city of Wuxi, in Jiangsu province, China.
The Sunway TaihuLight was the world’s fastest supercomputer for two years, from June 2016 to June 2018, according to the TOP500 lists. The record was surpassed in June 2018 by IBM’s Summit.
TIANHE-2
Tianhe-2 or TH-2 (Chinese: 天河-2; pinyin: tiānhé-èr; literally: ‘Heavenriver-2’, i.e. ‘Milky Way 2’) is a 33.86-petaflops supercomputer located in the National Supercomputer Center in Guangzhou, China. It was developed by a team of 1,300 scientists and engineers.
It was the world’s fastest supercomputer according to the TOP500 lists for June 2013, November 2013, June 2014, November 2014, June 2015, and November 2015. The record was surpassed in June 2016 by the Sunway TaihuLight. In 2015, plans of the Sun Yat-sen University in collaboration with Guangzhou district and city administration to double its computing capacities were stopped by a US government rejection of Intel’s application for an export license for the CPUs and coprocessor boards.
In response to the US sanction, China introduced the Sunway TaihuLight supercomputer in 2016, which substantially outperforms the Tianhe-2 (and also affected the update of Tianhe-2 to Tianhe-2A replacing US tech), and now ranks fourth in the TOP500 list while using completely domestic technology including the Sunway manycore microprocessor.
FRONTERA – DELL
In 2018, the National Science Foundation (NSF) awarded a $60 million grant to the Texas Advanced Computing Center (TACC) to deploy a new petascale computing system, Frontera. Deployed in June 2019, Frontera is the 5th most powerful supercomputer in the world, and the fastest supercomputer on a university campus.

It’s powered by Dell C6420, Xeon Platinum 8280 28C 2.7GHz, Mellanox InfiniBand HDR , Dell EMC with 448,448 cores.
Up to 80% of the available hours on Frontera, more than 55 million node hours each year, will be made available through the NSF Petascale Computing Resource Allocation program. Frontera achieved 23.5 PetaFLOPS on the high-performance LINPACK benchmark, a measure of the system’s floating point computing power. To match what Frontera can compute in just one second, a person would have to perform one calculation every second for about a billion years. The main system’s theoretical peak performance will be 38.7 PetaFLOPS.
PIZ DAINT– CRAY
Piz Daint is a supercomputer in the Swiss National Supercomputing Centre, named after the mountain Piz Daint in the Swiss Alps. It is powered by Cray XC50, Xeon E5-2690v3 12C 2.6GHz, Aries interconnect, NVIDIA Tesla P100 with 387,872 cores.

Future of AI-powered Smartest machines
According to HP CEO Meg Whitman, “The secrets to the next great scientific breakthrough, industry-changing innovation or life-altering technology hide in plain sight behind the mountains of data we create every day. To realize this promise, we can’t rely on the technologies of the past, we need a computer built for the big data era.”
From the high definition movies, we stream, to the weather, traffic and other satellite info we use, the future lies in plain old number-crunching. That’s what supercomputers do best. Technology is easy to be taken for granted, yet it can have an incredible impact, both beneficial or adverse, on our lives. We are yet to see the true extent of its potential.
