NVlink will be the backbone of 150 Petaflop Coral supercomputers coming to ORNL and LLNL. As the world’s first high-speed GPU interconnect, NVLink will let data move between GPUs and CPUs 5-12 times faster than possible today.

Test Bed Systems Pave the Way for 150 Petaflop Summit Supercomputer

Philip Curtis, a member of the High-Performance Computing Operations group at the OLCF, works with Pike, one of the test systems being used to prepare for Summit.

Oak Ridges is preparing for their upcoming Summit supercomputer with two modest test bed systems using Power8 processors. “Summit will deliver more than five times the computational performance of Titan’s 18,688 nodes, using only approximately 3,400 nodes when it arrives in 2017.”

Slidecast: Nvidia/IBM to Build Two Coral 100+ Petaflop Supercomputers in 2017

In this slidecast, Sumit Gupta from Nvidia describes the company’s big win with IBM for two DOE supercomputers for deployment in 2017. The two machines will feature IBM POWER9 processors coupled with Nvidia’s future Volta GPU technology. NVLink will be a critical piece of the architecture as well, along with a system interconnect powered by Mellanox.
