In this video, Satinder Nijjar from NVIDIA describes the new DGX-2 GPU supercomputer.

Experience new levels of AI speed and scale with NVIDIA DGX-2, the first 2 petaFLOPS system that combines 16 fully interconnected GPUs for 10X the deep learning performance. It’s powered by NVIDIA DGX software and a scalable architecture built on NVIDIA NVSwitch, so you can take on the world’s most complex AI challenges.”


As the backbone of the DGX-2, NVIDIA NVSwitch is the first on-node switch architecture to support 16 fully-connected GPUs in a single server node and drive simultaneous communication between all eight GPU pairs at an incredible 300 GB/s each. These 16 GPUs can be used as a single large-scale accelerator with 0.5 Terabytes of unified memory space and 2 petaFLOPS of deep learning compute power.

DGX-2 is our first server to usher in our new SXM3 form factor. So a new form factor for the GPU,” said Marc Hamilton from NVIDIA. “In size, it’s sort of very similar. That 3×5″ sort of high-density form factor that we introduced with SXM2 back in the Pascal days, but now SXM3 will take us through Volta and beyond. Next, of course, it’s built with our new 32 gig HBM 2 memory parts. So each of those 16 GPUs has 32 gig of HBM2 memory. So that’s in one box, you have half a terabyte of HBM2 memory.”
