Accelerated computing powering world’s fastest supercomputer
Call it the most powerful scientific tool ever built. Call it a new paradigm of computing. Just don’t call it slow, because whatever number you look at, Summit — which made its debut at the Oak Ridge National Laboratory — is flat-out fast. This massive machine, powered by 27,648 of Volta Tensor Core GPUs, can perform more than three exaops, or 3 billion billion calculations per second. That’s more than 100 times faster than Titan, previously the fastest U.S. supercomputer, completed just five years ago. And 95 percent of that computing power comes from GPUs. Built for the U.S. Department of Energy, this is a machine designed to tackle the grand challenges of our time. It will accelerate the work of the world’s best scientists in high-energy physics, materials discovery, healthcare and more, with the ability to crank out 200 petaflops of computing power to high-precision scientific simulations. This is, literally, a scientific time machine. The story behind the story: The team at Oak Ridge was the first to realise — almost a decade ago — that a new kind of computing was needed. The old paradigm of piling one transistor on top of another wouldn’t deliver the efficiency they needed. They took a risk and built Titan in 2012, the world’s fastest supercomputer, with one GPU in every node. That courage paid off. Now over 550 HPC applications are accelerated with GPUs, and all of the 15 most widely used ones. Their work reshaped supercomputing. Writing Computing’s Next Chapter Summit is the next chapter. Not just for ORNL, but for all of computing. The research team has been working with the DOE for more than 11 years on advanced technologies, including the Volta GPUs and NVLink high-speed interconnect technology at the very heart of Summit. Instead of one GPU per node, Summit has six Tensor Core […]
