NVLink
NVLink is a communications protocol developed by Nvidia. NVLink specifies a point-to-point connection between a CPU and a GPU and also between a GPU and another GPU rated at 80 GB/s.[1] NVLink products introduced to date focus on the high-performance application space.
On 5 April 2016, Nvidia announced that NVLink will be implemented in the forthcoming Pascal-microarchitecture-based GP100 GPU, which will be used in, for example, Nvidia Tesla P100 products.[2]
The US Department of Energy contracted Nvidia and IBM to build two supercomputers named "Summit" and "Sierra",[3] which will use NVLink for the node interconnects, while a variant of InfiniBand will be used for the system interconnects.[4] These systems will combine Nvidia's Volta architecture with the POWER9 family of CPUs.
