Welcome to HPC Newsbytes, a weekly show about important news in the world of supercomputing, AI, quantum computing, and other advanced technologies. Hi, everyone. Welcome to HPC Newsbytes. I'm Doug Black, and with me is Shaheen Khan. Japan plans a giant, nearly 30,000 GPU national AI supercomputer that they're building with NVIDIA. Last week, NVIDIA announced it's partnering with Japan's Notra Corporation to build a 140 megawatt AI factory, with 27,500 Ruben GPUs and 13,750 Vera CPUs. The system is called Frontia, F-F-R-O-N-T-I-A, Japan's state-sponsored physical AI program. The facility will train open multimodal foundation models for robotics, digital twins, and industrial automation.

AI is starting to be incorporated into the economies of various countries, so they are trying to keep up with AI by leaning into their strengths. For Japan, that means a bet on manufacturing, robotics, or more generally physical AI, and using a national platform to pool compute, industrial data, and engineering talent. The U.S. leads in core hardware and software technologies, investment and cloud infrastructure. China is building domestic chips, open models, and state-backed ecosystems, and Europe is emphasizing trusted AI and industrial applications, while South Korea and Taiwan are reinforcing their semiconductor strengths. At the same time, leadership in frontier models may become less decisive, as AI models tend to commoditize, advantage would shift towards domain expertise,

integration, and deployment. unless new breakthroughs reset the landscape like LLMs did, and such breakthroughs could come from anywhere. The sovereignty question is also evolving. In this case, the system is from Nvidia, but Japan could view it as just a tool while it retains control over how the system is used. Countries are building AI strengths in different and complementary ways.

That may be the really important insight. The theory would be AI is human-skirts, and therefore global in scope, making it so large and complex that realizing its potential and avoiding its pitfalls may require complementary efforts across many countries. New export rules for AI chips are coming from the U.S. government. The changes have been expected for some time, but what they might be remains unclear. At a hearing in Washington last week, under Secretary of Commerce Jeffrey Kessler did not release the scope timing chip thresholds.

coverage or compliance rules. All of this stems from the Trump administration's decision last year to rescind the Biden administration's AI, quote, diffusion rule, unquote, designed to form a licensing system for AI chips, creating a tiered list of countries and the access they have to U.S. technology. President Trump's Commerce Department officials say the Biden era rule is too restrictive, but to date they haven't been able to come up with a replacement set of rules. As we've discussed here a few times, export controls have an important impact, but they also carry costs.

Those costs can accumulate even as the benefits dissipate. So controls are most justified when their short-term impact is game-changing rather than simply adding friction to the existing situation. And that may be the case here. That moves the analysis to the longer term. Broadly speaking, controls can buy time, especially if they meaningfully change the game, but they also raise the payoff for domestic substitutes, incentivize efforts on architectural

efficiency and alternative supply chains, and trigger efforts by the other side to change the game again. Staying on the topic of China, it used the World Artificial Intelligence Conference in Shanghai to present a more explicit alternative to the U.S.-led AI order. Chinese President Xi Jinping promoted open source AI, wider access for developing countries, and a new World AI Cooperation Organization, initially backed by 29 countries. China is positioning the organization around development, sovereignty, and access to AI capability, rather than what they say is the Western emphasis on political values, rights, and safety governance.

It is also offering practical incentives, training, cooperation centers, models and technology that countries can deploy without joining a tightly controlled U.S. ecosystem. This goes beyond diplomatic language, offer models, a technology supply chain, and enough implementation capacity to package AI infrastructure for countries that cannot build it themselves. Well, speaking of changing the game, China is trying to move the discussion from who has the best technology to first formulating a need for a global AI ecosystem, and then who can offer the best possible path towards it. The US provides the leading edge in technologies, know-how, and

investment. So China's competing through open models, lower-cost infrastructure, financing, and promoting its technology accomplishments, like it did with its CPU-only number one system on the top 500. Its narrative also seems to include, shall we say, a different alignment model at a time when U.S. policy appears to demand sharper alignment from partners. Despite the contradictions in China's narrative, for example, advocating openness internationally while maintaining extensive control over technology at home, and despite concerns about future dependence, their message could resonate in parts of the global south and even among some Western countries. Some countries may find it enticing to get lower costs.

AI capability now and worry about long-term issues later, especially if it's readily available and comes with fewer overt political strings. For now, the decisive and growing advantage of U.S. technologies makes the American ecosystem the top choice. All right, that's it for this episode. Thank you all for being with us.
