Supercomputing a new frontier of national sovereignty and global competitiveness

Experts warn that a growing ‘compute divide’ is redrawing the map of global competitiveness. Once limited to specialized laboratories, high-performance computing (HPC) has now emerged as a primary driver of economic growth, national security, and scientific leadership.

Access to massive processing power is now as vital to a nation’s future as food security or energy independence. That is according to a new report from the World Governments Summit and management consultancy Sia, which warns of a potential gap that could see technologically superior nations leading and the rest quickly falling behind.

The evolution of these supercomputers has reached a milestone known as exascale computing, which allows for billions of billions of calculations every second. This immense power is fueling a virtuous cycle with artificial intelligence, where each technology accelerates the development of the other. As of now, the US is home to the only three confirmed exascale computing systems, though China and Europe are not far behind.

The report also warns of an increasingly dire supply chain vulnerability when it comes to the complex hardware needed for HPCs, including processors, accelerators (GPUs), and memory. These all require advanced chips, of which 90% are produced in Taiwan. Any disruptions – like trade disputes or geopolitical tension – that could throw this supply into turmoil, could cause big problems down the line.

Huge potential for HPC

The report stresses that nations that successfully harness high-performance computing systems will see significant returns, with researchers estimating that such technology has generated $3 trillion in economic value over the last 25 years.

“The ability for AI to empower virtually any sector is moving HPC out of the laboratory and expanding its scope for influence geopolitically,” the report notes.

Indeed AI is not just a beneficiary, but is actually accelerating further advances in HPC. This ‘blurring of the line’ between AI research and supercomputing development explains why the stakes are so high.

Beyond economics, these machines are solving some of the most complex challenges facing humanity. In healthcare, they allow doctors to map genetic mutations and design personalized treatments tailored to individual patients.

When it comes to the energy sector, supercomputers simulate plasma behavior for fusion reactors and optimize wind farms to support a transition to sustainable power. Furthermore, they provide critical infrastructure for national defense by simulating battlefield scenarios and detecting cyber threats in real time.

“We’ve reached a point where HPC isn’t just a niche tool anymore. It’s a pillar of national security,” said Rafael Lemaitre, partner at Sia. “Your ability to compute is now a structural part of how you protect your interests, grow your economy, and more importantly, future-proof it.”

Obstacles to taking full advantage of HPC

The report identifies several hurdles that could stall progress in developing HPC systems. One major concern is the staggering amount of electricity required to run these systems, which can consume as much power as a small town.

While European nations lead in using renewable energy for their computing centers, global energy consumption for data centers is projected to nearly quadruple by the end of the decade. Additionally, a global shortage of specialized talent means that many countries must rely on a small pool of international experts to operate their infrastructure.

Geopolitical risks also loom large due to highly concentrated supply chains. To mitigate the risks related to over-reliance on just a few exporters of advanced chips, the report urges governments to treat computing power as essential national infrastructure.

One additional challenge is a lingering talent gap, which the report notes “can’t be fixed overnight”. Many countries will need to import expertise because the global pool of qualified experts is very limited. This lack of talent is perhaps just as much a constraint as the hardware.

The findings emphasize that the next decade will be defined by how well nations adapt to this new era. Those that invest in their own computing capacity and develop local talent will likely lead the global economy. Conversely, countries that lack these resources may find it increasingly difficult to maintain their sovereignty or compete on the world stage.

“Sovereignty isn’t about chasing every tech fad,” says Lemaitre. “It’s about making sure your country has the right tools, in the right places, to keep the lights on and the economy moving, no matter what happens globally.”
