Volta-Powered Supercomputers to Supercharge AI, Scientific Discovery

by Jamie Beckett

The just-released TOP500 supercomputer list shows a record 34 new NVIDIA-accelerated systems, bringing our total to 87.

But we’re only just getting started. By the time the next list surfaces in June, some of the first supercomputers with our new Volta GPU architecture will be online. Summit, at Oak Ridge National Laboratory (ORNL), will be among the world’s most powerful. Not far behind are Sierra, at Lawrence Livermore National Laboratory in the U.S., and AI Bridging Cloud Infrastructure (ABCI) in Japan.

The three are in the spotlight this week as makers of the world’s most powerful supercomputers gather for SC17 in Denver.

At the show this week, you can attend a variety of talks and exhibits to learn more about how GPUs and Volta will advance science and AI.

AI Extends HPC

Volta delivers 5x the performance of its predecessor, Pascal. Like Pascal, it combines AI and traditional HPC applications on single platform.

High performance computing is a cornerstone of modern science, allowing researchers to simulate and predict what’s likely to happen in the real world — for example, the body’s response to a new drug treatment, or the efficiency of a new energy source. By combining AI and HPC, Volta lets researchers use AI to gain insights from data to speed up scientific discovery.

Summit, Sierra and ABCI are all powered by NVIDIA Tesla V100 GPU accelerators, which pack the computing power of 100 CPUs into a single GPU, while using half the energy of our previous-generation GPUs. The three contain a combination of CPUs and GPUs, all linked by our NVIDIA NVLink high-speed interconnect technology.

Scaling New Heights with Summit

Summit is chartered to meet the insatiable need for computing resources by the world’s researchers and scientists. With expected peak performance at 200 petaflops (and over three exaflops for AI), it will top the reigning world champion of supercomputing, China’s Sunway TaihuLight, which has a peak of 125.4 petaflops. It will have more than 5x the computing power of ORNL’s Titan supercomputer, long the most powerful system in the U.S.

“For us, it’s not about the peak performance. It’s about the science we can do with Summit,” said Tjerk Straatsma, group leader for scientific computing at ORNL’s National Center for Computational Sciences.

With the added computing power, researchers can solve larger and more challenging problems, perform more accurate simulations and make more accurate predictions, Straatsma said. For example, one project planned for Summit is designed to forecast the long-term effects of climate change. Other applications could speed drug discovery, make plant-based fuels more cost effective or enable fusion as a source of clean, abundant energy.

High Sierra

Sierra will be the U.S. Department of Energy’s primary system for managing and securing the nation’s nuclear weapons, and managing nuclear nonproliferation and counterterrorism programs. With expected peak performance of 125 petaflops, Sierra delivers five to 10 times the performance of Sequoia, the current fastest system at LLNL.

With the added capability, scientists will be able to carry out simulations with higher fidelity and run three-dimensional simulations that are out of reach of today’s high-performance computers, said Chris Clouse, associate program director for computational physics at LLNL.

The lab also plans to use Sierra for basic science applications and AI research designed to make simulations more robust and accurate, he said.

Designed for AI

ABCI, operated by Japan’s National Institute of Advanced Industrial Science and Technology, will come online as a global innovation platform for AI in 2018. With a planned peak of 37 petaflops and 550 petaflops for deep learning, ABCI will be that nation’s fastest supercomputer.

Tailored for AI, machine learning and deep learning, ABCI will “accelerate the deployment of AI into real businesses and society,” AIST said.

SC17 Highlights

At SC17, you can learn more more about Volta supercomputers in development by attending talks at the NVIDIA GPU Technology Theater or by visiting our booth 1809 in the exhibit hall. We’re hosting more than 30 talks about how HPC, accelerated supercomputing and deep learning are advancing computational science. Here are a few highlights:

    Love the progress and hope for more great science to come from these efforts. We have yet to reverse engineer exactly how life first started up on the Earth as that would teach us how life could start up around distant planets and if or where life may be elsewhere in our Galaxy or Universe. I hope they can use these computers/tools to better predict the routes of Hurricanes in the future to save lives and predict the effects of global warming how how to best offset our negative human impact. As data will start to roll in from new telescopes in the future we will need to better analyze in visual ways what atmospheres could be created from geological methods or from possible lifeforms. Also what is dark matter and dark energy and can you create enough simulations or models that will crack these mysteries. Maybe in the future we figure out how to hook up all of these supercomputers together into 1 massive brain that works together or at least brings more experts together to solve the biggest mysteries and challenges in Science. Hurry up and fix Alzheimer’s disease… or just use Crispr9 to stop the spread of diseases through insects and so on…. then fix this aging problem and all other diseases. I hope our DNA is just a very complex computer code that we can unlock and then take total control of to improve and tools like this will prove critical as the stepping stones for unlocking all of science’s mysteries.
