Nvidia launched its second-generation DGX system in March. In order to build the 2 petaflops half-precision DGX-2, Nvidia had to first design and build a new NVLink 2.0 switch chip, named NVSwitch. While Nvidia is only shipping NVSwitch as an integral component of its DGX-2 systems today, Nvidia has not precluded selling NVSwitch chips to data center equipment manufacturers.
This article will answer many of the questions we asked in our first look at the NVSwitch chip, using DGX-2 as an example architecture.
Nvidia’s NVSwitch is a two-billion transistor non-blocking switch design incorporating 18 complete NVLink 2.0 ports …Read more
