NVLink

NVLink is a wire-based serial, multi-lane, near-range, communications link developed by Nvidia. Unlike PCI Express, a device can consist of multiple NVLinks, and devices can use mesh networking to communicate instead of a central hub/switch. The protocol was first announced in March 2014 and uses a proprietary high-speed signaling interconnect (NVHS).
