The Back End AI Network Puts Pressure On The Front End
For most of the history of high performance computing, a supercomputer was a freestanding, isolated machine that was designed to run some simulation or model and the only link it needed to the outside world was a relatively small one to show some visualization. …

Copper Wires Have Already Failed Clustered AI Systems
It has become a well known fact these days that the switches that are used to interconnect distributed systems are not the most expensive part of that network, but rather it is the optical transceivers and fiber optic cables that comprise the bulk of the cost. …
