SAN FRANCISCO, ⁠June 15 (Reuters) - Cornelis, an Intel spinout developing networking technology ⁠aimed at data centers, on Tuesday said that its ‌chips are now being used by a U.S. supercomputer used for nuclear weapons work.

Under the National Nuclear Security Administration, a trio of U.S. national labs works ​to develop and maintain the nation's nuclear ⁠weapons with extremely accurate computer ⁠simulations of nuclear reactions, one of the most demanding tasks in ⁠the ‌entire computing industry. Lawrence Livermore National Laboratory said Tuesday that it has tapped Cornelis chips to connect 952 ⁠computers in its new "Lynx" system.

The Lynx system is ​part of a $70 ‌million program at the three labs to build workhorse supercomputers ⁠out of ​standard, off-the-shelf components from the computing industry.

Cornelis, which spun out of Intel in 2020 and in which the chipmaker remains a minority shareholder, ⁠is developing a networking technology called Omni-Path ​that seeks to challenge rival networking chips from Nvidia, Broadcom for applications where a computing problem is so large that it must ⁠be spread out over many different computers.

One of the features of Cornelis chips is traffic routing technology that, for example, recognizes when it may be faster to send data to a computer ​that's further away if all nearby computers ⁠are clogged with network traffic.

"You might drive a mile longer, but ​you get there 10 minutesfaster because ‌you avoided the stadium trafficfrom the ​FIFA World Cup," said Lisa Spelman, CEO of Cornelis.
