Having a slow connection is always frustrating, but just imagine how supercomputers feel. All those cores doing all kinds of processing at lightning speed, but in the end they’re all waiting on an outdated network interface to stay in sync. DARPA doesn’t like it. So DARPA wants to change it — specifically by making a new network interface a hundred times faster.

The problem is this. As DARPA estimates it, processors and memory on a computer or server can in a general sense work at a speed of roughly 10^14 bits per second — that’s comfortably into the terabit region — and networking hardware like switches and fiber are capable of about the same.

Network - Interface - Form - Card - NIC

That network interface usually takes the form of a card (making it a NIC) and handles accepting data from the network and passing it on to the computer’s own systems, or vice versa. Unfortunately its performance is typically more in the gigabit range.

That delta between the NIC and the other components of the network means a fundamental limit in how quickly information can be shared between different computing units — like the hundreds or thousands of servers and GPUs that make up supercomputers and datacenters. The faster one unit can share its information with another, the faster they can move on to the next task.

Think - Apple - Farm - Apple - People

Think of it like this: You run an apple farm, and every apple needs to be inspected and polished. You’ve got people inspecting apples and people polishing apples, and both can do 14 apples a minute. But the conveyor belts between the departments only carry 10 apples per minute. You can see how things would pile...
