Researchers To Tap NVLink To Power Next-Gen Research

The Oak Ridge National Laboratory’s Summit supercomputing system is being built to power research that could change the world. When it’s completed and available in 2018, the GPU-accelerated machine will be capable of delivering 150 to 300 peak petaflops of computational performance. That’s at least five times more than Oak Ridge’s Titan, the fastest supercomputer in the U.S. today. To make use of all this performance, this extraordinary new machine is attracting extraordinary new applications. That’s why the lab today announced 13 projects for its Center for Accelerated Application Readiness (CAAR).

Summit will be powered by NVIDIA’s Volta GPU architecture, which features an advanced technology called NVLink. NVLink accelerates these powerful applications with a new kind of high-speed interconnect technology between Summit’s IBM POWER CPUs and our next-generation NVIDIA GPU accelerators. This allows them to exchange data 5 to 12 times faster than they can with current interconnect technologies.
