Welcome to the third entry on this sequence on AI. The primary one was an introduction and sequence overview and the following mentioned the aspirational aim of synthetic normal intelligence, AGI. Now it’s time to zero in on one other well timed matter—HPC customers’ reactions to the convergence of HPC and AI.
A lot of this content material is supported by our in-depth interviews at Intersect360 Analysis with HPC and AI leaders world wide. As I mentioned within the intro column, the sequence doesn’t intention to be definitive. The aim is to put out a spread of present info and opinions on AI for the HPC-AI group to contemplate. It’s early and nobody has the ultimate tackle AI. Feedback are at all times welcome at steve@intersect360.com.
AI Depends Closely on HPC Infrastructure and Expertise
HPC and AI are symbiotes, creations locked in a decent, mutually helpful relationship. Each dwell on an analogous, HPC-derived infrastructure and frequently alternate advances—siblings sustaining shut contact.
- HPC infrastructure permits the AI group to develop refined algorithms and fashions, speed up coaching and carry out speedy evaluation in solo and collaborative environments.
- Shared infrastructure parts originating in HPC embody standards-based clusters, message-passing (MPI and derivatives), high-radix networking applied sciences, storage and cooling applied sciences, to call a number of. MPI “forks” utilized in AI (e.g., MPI-Bcst, MPIAllreduce, MPI_Scatterv/Gatherv) present helpful capabilities effectively past fundamental interprocessor communication.
- However HPC’s biggest reward to AI is a long time of expertise with parallelism—particularly helpful now that Moore’s Legislation-driven progress in single-threaded processor efficiency has sharply decelerated.

The infrastructure overlap runs deep. Not way back, a profitable designer of interconnect networks for leadership-class supercomputers was employed by a hyperscale AI chief to revamp the corporate’s international community. I requested him how totally different the supercomputer and hyperscale growth duties are. He mentioned: “Not a lot. The ideas are the identical.”
This anecdote illustrates one other main HPC contribution to the mainstream AI world–cloud providers suppliers, social media and different hyperscale firms: gifted individuals who adapt wanted parts of the HPC ecosystem to hyperscale environments. Through the previous decade, this expertise migration has helped gasoline the expansion of the mainstream AI market—at the same time as different gifted individuals stayed put to advance modern, “frontier AI” throughout the HPC group.
HPC and Hyperscale AI: The Knowledge Distinction
Social media giants and different hyperscalers had been in a pure place to get the AI ball rolling in a severe method. That they had a lot of available buyer information for exploiting AI. In sharp distinction, some economically essential HPC domains, resembling healthcare, nonetheless battle to gather sufficient usable, high-quality information to coach massive language fashions and extract new insights.
It’s no accident, for instance, that UnitedHealth Group reportedly spent $500 million on a brand new facility in Cambridge, Massachusetts, the place tech-driven subsidiary Optum Labs and companions together with the Mayo Clinic and Johns Hopkins College can pool information sources and experience to take advantage of frontier AI. The Optum collaborators now have entry to usable (deidentified, HIPAA-compliant) information on greater than 300 million sufferers and medical enrollees. An essential intention is for HPC and AI to companion in precision medication, by making it attainable to rapidly sift by way of thousands and thousands of archived affected person information to determine therapies which have had the perfect success for sufferers intently resembling the affected person beneath investigation.

The pharmaceutical business additionally has a scarcity of usable information for some essential functions. One pharma exec informed me that the provision of usable, high-quality information is “minuscule” in contrast with what’s actually wanted for precision medication analysis. The info scarcity difficulty extends to different economically essential HPC-AI domains, resembling manufacturing. Right here, the scarcity of usable information could also be as a result of isolation in information silos (e.g., provide chains), lack of standardization, or easy shortage.
This may have penalties for all the pieces from HPC-supported product growth to predictive upkeep and high quality management.
Addressing the Knowledge Scarcity
The HPC-AI group is working to treatment the information scarcity in a number of methods:
- A rising ecosystem of organizations is creating practical artificial information, which guarantees to broaden information availability whereas offering higher privateness safety and avoidance of bias.
- The group is growing higher inferencing—guessing potential. Larger inferencing “brains” ought to produce desired fashions and options with much less coaching information. It’s simpler to coach a human than a chimpanzee to “go to the closest grocery retailer and convey again a quart of milk.”
- The current DeepSeek information confirmed, amongst different issues, that spectacular AI outcomes will be achieved with smaller, much less generalized (extra domain-specific) fashions that require much less coaching information—together with much less time, cash and vitality use. Some consultants argue that a number of small language fashions (SLMs) are more likely to be more practical than one massive language mannequin (LLM).
Helpful Convergence or Scary Collision?
Attitudes of HPC middle administrators and main customers towards the HPC-AI convergence differ vastly. All count on mainstream AI to have a robust impression on HPC, however expectations vary from assured optimism to various levels of pessimism.
The optimists level out that the HPC group has efficiently managed difficult, finally helpful shifts earlier than, resembling migrating apps from vector processors to x86 CPUs, transferring from proprietary working techniques to Linux, and including cloud computing to their environments. The group is already placing AI to good use and can adapt as wanted, they are saying, although altering would require one other main effort. Extra good issues will come from this convergence. Some HPC websites are already far alongside in exploiting AI to help key purposes.

The pessimists are inclined to worry the HPC-AI convergence as a collision, the place the massive mainstream AI market overwhelms the smaller HPC market, forcing scientific researchers and different HPC customers to do their work on processors and techniques optimized for mainstream AI and never for superior, physics-based simulation. There may be motive for concern, though HPC customers have needed to flip to mainstream IT markets for know-how previously. As somebody identified in a panel session on future processor architectures I chaired on the current EuroHPC Summit in Krakow, the HPC market has by no means been sufficiently big financially to have its personal processor and has needed to borrow extra economical processors from bigger, mainstream IT markets—particularly x86 CPUs after which GPUs.
Issues That Could Maintain Optimists and Pessimists Up at Night time
Listed here are issues within the HPC-AI convergence that appear to concern optimists and pessimists alike:
- Insufficient entry to GPUs. GPUs have been briefly provide. A priority is that the superior buying energy of hyperscalers—the largest prospects for GPUs—could make it troublesome for Nvidia, AMD and others to justify accepting orders from the HPC group.
- Strain to Overbuy GPUs. Some HPC information middle administrators, particularly within the authorities sector, informed us that AI “hype” is so robust that their proposals for next-generation supercomputers needed to be replete with mentions of AI. This later compelled them to observe by way of and purchase extra GPUs—and fewer CPUs—that their consumer group wanted.
- Problem Negotiating System Costs. A couple of HPC information middle director reported that, given the GPU scarcity and the superior buying energy of hyperscalers, distributors of GPU-centric HPC techniques have turn out to be reluctant to enter into customary value negotiations with them.
- Persevering with Availability of FP64. Some HPC information middle administrators say they’ve been unable to get assurance that FP64 items might be obtainable for his or her subsequent supercomputers a number of years from now. Double precision isn’t important for a lot of mainstream AI workloads and distributors are growing sensible algorithms and software program emulators aimed toward producing FP64-like outcomes run at decrease or blended precision.
Preliminary Conclusion
It’s early within the recreation and already clear that AI is right here to remain—not one other “AI winter.” Equally, nothing goes to cease the HPC-AI convergence. Even pessimists foresee robust advantages for the HPC group from this highly effective pattern. HPC customers in authorities and tutorial settings are transferring full pace forward with AI analysis and innovation, whereas HPC-reliant industrial corporations are predictably extra cautious however have already got purposes in thoughts. Oil and fuel majors, for instance, are beginning to apply AI in different vitality analysis. The airline business tells us AI received’t substitute pilots within the foreseeable future, however with at this time’s international pilot scarcity, some cockpit duties can most likely be safely offloaded to AI. There are some actual considerations as famous above, however most HPC group members we speak with consider that the HPC-AI convergence is inevitable, it can deliver advantages and the HPC group will adapt to this shift because it has to prior transitions.
