Summit GPU Supercomputer Enables Smarter Science

Originally published at: https://developer.nvidia.com/blog/summit-gpu-supercomputer-enables-smarter-science/

Today the world of open science received its greatest asset in the form of the Summit supercomputer at Oak Ridge National Laboratory (ORNL). This represents an historic milestone because it is the world’s first supercomputer fusing high performance, data-intensive, and AI computing into one system. Summit is capable of delivering a peak 200 petaflops, ten…

The best technology in the world

Until the Chinese steal the design and make a faster one. Suspect they already have bribed the right folks.

NVLink is very fast (300GB/s), but would the speed be bottlenecked by the inter-node connection? What is the inter-node bandwidth (or data rate) of the networking within this supercomputer? Thanks a lot!
