1. Summit

The $200 million supercomputer is an IBM AC922 system utilizing 4,608 compute servers containing two 22-core IBM Power9 processors and six Nvidia Tesla V100 graphics processing unit accelerators each. Summit is also (relatively) energy-efficient, drawing just 13 megawatts of power, compared to the 15 megawatts TaihuLight pulls in. Summit boasts a peak performance of 200,000 trillion calculations per second and will be eight times more powerful than America’s current top-ranked system, Titan. It took four years to build, according to Romett

2. Sunway TaihuLight

Currently ranked as the fastest supercomputer in the world, the Sunway TaihuLight supercomputer measures in at 125 petaFLOPS (theoretical peak)—five times as fast as the supercomputer in second place. Housed in the National Supercomputing Center in Wuxi, it is comprised of 10.6 million cores and is being used for climate research, earth systems modeling and data analytics. On top of being the fastest supercomputer in the world, the Sunway TaihuLight is currently ranked as the fourth most energy-efficient one as well, requiring substantially fewer megawatts per megaFLOPS.

3. Sierra

Sierra, LLNL’s next-generation supercomputer, is projected to provide four to six times the sustained performance and be at least seven times more powerful than Sequoia, with a 125 petaFLOP/s peak  based on IBM’s Power9 chip

4. Tianhe-2 (MilkyWay-2)

In late 2016, the Piz Daint supercomputer in Lugano, Switzerland gained a huge hardware upgrade. That new power tripled its computing performance and brought its theoretical peak performance up to 19.6 petaFLOPS (their own measurementspin it currently at 25.3), making it the fastest supercomputer outside Asia. Named after a mountain in the Swiss Alps, the Piz Daint also creates advanced visualizations and high-resolution imaging simulations. It will soon provide processing power to the Large Hadron Collider at CERN, helping it analyze huge amounts of data.

5. AI Bridging Cloud Infrastructure (ABCI)

AI Bridging Cloud Infrastructure (ABCI) is a 130-petaflops supercomputer costing $173 million (£131 million). Japan’s new machine will be used in the field of Artificial Intelligence, which explains its rather boring name: “AI Bridging Cloud Infrastructure,” or ABCI. According to Satoshi Sekiguchi, a director-general at Japan’s ‎National Institute of Advanced Industrial Science and Technology, where the computer will be built, the system will also be used to “tap medical records to develop new services and applications.”

6. Piz Daint


Named after Piz Daint, a prominent peak in Grisons that overlooks the Fuorn pass, this supercomputer is a hybrid Cray XC40/XC50 system and is the flagship system for national HPC Service.

  • Piz Daint has been updated in Fall 2016 and incorporates the previous Cray XC30 named Piz Daint & Piz Dora.

  • Login Nodes:  Intel® Xeon® CPU E5-2650 v3 @ 2.30GHz (10 cores, 256 GB RAM)
  • Scratch capacity 6.2 PB


7. Titan

Perhaps one of the best-known supercomputers in the Western world, Titan at Tennessee’s Oak Ridge National Laboratory was the fastest supercomputer on the planet until the Tianhe-2 (below) jockeyed it out of first place in 2013. Titan is the first supercomputer to combine AMD Opteron CPUs and NVIDIA Tesla GPUs, bringing its total theoretical peak output to 27 petaFLOPS (Linpack approximates its output at 17.6). This kind of power enables researchers to perform the complex simulations needed in climate science, astrophysics, and molecular physics.

8. Sequoia

The Sequoia is a supercomputer built to measure the risks of nuclear warfare by making advanced weapons science calculations. It’s owned by the Lawrence Livermore National Laboratory in California. With 98,304 nodes, it’s ranked as the fifth most powerful supercomputer on the planet. According to the Linpack benchmark, it has a speed of 17.2 petaFLOPS.

9. Trinity

Trinity, a Cray XC40 supercomputer at the Laboratory, was recently upgraded with Intel “Knights Landing” Xeon Phi processors, which propelled it from 8.10 petaflops six months ago to 14.14 petaflops.

The Trinity project is managed and operated by Los Alamos National Laboratory and Sandia National Laboratories under the Alliance for Computing at Extreme Scale (ACES) partnership. The system is located at the Nicholas Metropolis Center for Modeling and Simulation at Los Alamos and covers approximately 5,200 square feet of floor space.

10. Cori (NERSC)

The National Energy Research Scientific Computing Center near Oakland, California named its newest supercomputer creation “Cori,” after Gerty Cori, the first American woman to win a Nobel Prize. The system is a Cray XC40, manufactured by the company responsible for major breakthroughs in supercomputer performance during the 1970s. Cori can theoretically achieve a processing speed of 29.1 petaFLOPS. It achieves this through the use of Haswell architecture Intel Xeon and Xeon Phi processors.
