Cornelis Networks releases tech to speed up AI datacenter connections
By Stephen Nellis
SAN FRANCISCO:
Cornelis Networks
on Tuesday released a suite of networking hardware and software aimed at linking together up to half a million artificial intelligence chips.
Cornelis, which was spun out of Intel in 2020 and is still backed by the chipmaker's venture capital fund, is targeting a problem that has bedeviled AI datacenters for much of the past decade:
AI computing chips
are very fast, but when many of those chips are strung together to work on big computing problems, the network links between the chips are not fast enough to keep the chips supplied with data.
Nvidia took aim at that problem with its $6.9 billion purchase in 2020 of networking chip firm Mellanox, which made networking gear with a network protocol called InfiniBand, which was created in the 1990s specifically for supercomputers.
Networking chip giants such as Broadcom and Cisco Systems are working to solve the same set of technical issues with Ethernet technology, which has connected most of the internet since the 1980s and is an open technology standard.
The Cornelis "CN5000" networking chips use a new network technology created by Cornelis called OmniPath. The chips will ship to initial customers such as the U.S. Department of Energy in the third quarter of this year, Cornelis CEO Lisa Spelman told Reuters on May 30.
Although Cornelis has backing from Intel, its chips are designed to work with AI computing chips from Nvidia, Advanced Micro Devices or any other maker using open-source software, Spelman said. She said that the next version of Cornelis chips in 2026 will also be compatible with Ethernet networks, aiming to alleviate any customer concerns that buying Cornelis chips would leave a data center locked into its technology.
"There's 45-year-old architecture and a 25-year-old architecture working to solve these problems," Spelman said. "We like to offer a new way and a new path for customers that delivers you both the (computing chip) performance and excellent economic performance as well."

Why Anthropic CEO Dario Amodei thinks a 10-year AI regulation freeze is dangerous
Dario Amodei, Chief Executive of AI firm Anthropic, has criticised a Republican proposal to halt state-level regulation of artificial intelligence for ten years, calling the measure "far too blunt" in a sharply worded opinion piece published inThe New York Times. The proposal, reportedly embedded within former President Donald Trump's revived tax cut bill, seeks to prevent individual US states from enforcing their own AI regulations. This move, backers say, is intended to create a unified national framework. However, it has faced significant pushback, including from a bipartisan coalition of state attorneys general who have already enacted safeguards against high-risk AI use. You may be interested in Amodei, whose company is backed by Amazon, argued that the rapid pace of AI advancement demands a more agile and balanced approach. 'A 10-year moratorium is far too blunt an instrument. AI is advancing too head-spinningly fast,' he wrote. 'Without a clear plan for a federal response, a moratorium would give us the worst of both worlds — no ability for states to act, and no national policy as a backstop.' Instead, Amodei called for a coordinated effort between the White House and Congress to develop a federal transparency standard. Such a framework, he suggested, would compel AI developers to openly disclose their testing methods, risk mitigation strategies, and national security considerations prior to releasing advanced models. Anthropic already shares these details publicly, Amodei noted, and rivals OpenAI and Google DeepMind have adopted similar practices. However, he cautioned that voluntary transparency may not be sustainable as AI systems become more powerful and commercial stakes rise. 'Legislative incentives may become necessary to ensure this openness continues,' he said. Amodei's intervention adds weight to calls for a federal framework that preserves public safety while ensuring that innovation is not stifled, a balance that may prove increasingly difficult to strike as AI tools become more sophisticated and deeply embedded in daily life.

India Helping Auto Industry Meet Chinese Officials On Rare Earth Export Ban: Sources
Quick Read Summary is AI generated, newsroom reviewed. The Indian government is facilitating discussions between auto companies and China's commerce ministry due to China's export ban on rare earth magnets. India plans to develop its own magnet policy and domestic manufacturing, but it may take time. New Delhi: The Prime Minister's Office and the Indian embassy in China are helping Indian auto companies to hold a meeting with the Chinese commerce ministry in Beijing amid the neighbouring country's ban on export of rare earth magnets, people with direct knowledge of the matter said. China controls 90 per cent of the processing of such magnets, also used in industries such as clean energy and defence, apart from the automotive industry. India's three ministries - Heavy Industries, External Affairs, and Industry and Commerce - are involved in the discussions, people familiar with the matter said. A 50-member delegation of representatives from original equipment manufacturers (OEMs), Society of Indian Automobile Manufacturers (SIAM), and Automotive Component Manufacturers Association of India (ACMA) planned to visit China this week, but that did not work out. India is likely to consider having a proper rare earth magnet policy of its own to avoid the risk of getting caught in such a situation again, but that would take two-three years. There has been no import of rare earth magnets from China and no new licence has been issued since April 4, the day China announced its export ban. India is looking to develop domestic manufacturing capabilities and is considering offering production-based fiscal incentives to companies, news agency Reuters reported quoting two unnamed sources. The scheme, being drafted by the Ministry of Heavy Industries, also envisions partly funding the difference between the final price of the homegrown magnet and the cost of the Chinese imports. This would help achieve cost parity and boost local demand, Reuters reported, adding that funding for the scheme has yet to be decided, with the government likely to meet industry officials next week to finalise the details. The government company IREL (India) Ltd has been mining rare earth material for years, which are mainly used by atomic energy and defence units, with most supplies for other uses still imported from China. In Japan, Suzuki Motor has suspended production of its Swift car because of China's curbs.
