Welcome to the third entry on this collection on AI. The primary one was an introduction and collection overview and the following mentioned the aspirational objective of synthetic basic 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 all over the world. As I stated within the intro column, the collection doesn’t purpose to be definitive. The objective is to put out a variety 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 all the time 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 reside on the same, HPC-derived infrastructure and regularly alternate advances—siblings sustaining shut contact.
- HPC infrastructure permits the AI group to develop refined algorithms and fashions, speed up coaching and carry out fast evaluation in solo and collaborative environments.
- Shared infrastructure parts originating in HPC embrace 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 properly past primary interprocessor communication.
- However HPC’s best reward to AI is many years 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 world community. I requested him how totally different the supercomputer and hyperscale growth duties are. He stated: “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 corporations: proficient individuals who adapt wanted parts of the HPC ecosystem to hyperscale environments. In the course of the previous decade, this expertise migration has helped gasoline the expansion of the mainstream AI market—at the same time as different proficient individuals stayed put to advance modern, “frontier AI” inside the HPC group.
HPC and Hyperscale AI: The Knowledge Distinction
Social media giants and different hyperscalers have been in a pure place to get the AI ball rolling in a critical method. That they had numerous available buyer information for exploiting AI. In sharp distinction, some economically vital HPC domains, equivalent to healthcare, nonetheless battle to gather sufficient usable, high-quality information to coach giant 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 assets and experience to use frontier AI. The Optum collaborators now have entry to usable (deidentified, HIPAA-compliant) information on greater than 300 million sufferers and medical enrollees. An vital purpose is for HPC and AI to companion in precision medication, by making it doable to shortly sift by means of thousands and thousands of archived affected person information to establish therapies which have had the most effective success for sufferers intently resembling the affected person below investigation.

The pharmaceutical trade additionally has a scarcity of usable information for some vital functions. One pharma exec advised 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 challenge extends to different economically vital HPC-AI domains, equivalent to manufacturing. Right here, the scarcity of usable information could also be because of isolation in information silos (e.g., provide chains), lack of standardization, or easy shortage.
This could have penalties for all the things 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 life like artificial information, which guarantees to increase information availability whereas offering higher privateness safety and avoidance of bias.
- The group is creating 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 produce again a quart of milk.”
- The latest DeepSeek information confirmed, amongst different issues, that spectacular AI outcomes might be achieved with smaller, much less generalized (extra domain-specific) fashions that require much less coaching information—together with much less time, cash and power use. Some consultants argue that a number of small language fashions (SLMs) are more likely to be simpler than one giant language mannequin (LLM).
Useful Convergence or Scary Collision?
Attitudes of HPC heart administrators and main customers towards the HPC-AI convergence differ enormously. All count on mainstream AI to have a strong 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, equivalent to 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, regardless that 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 functions.

The pessimists are likely to worry the HPC-AI convergence as a collision, the place the big 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’s cause 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 latest EuroHPC Summit in Krakow, the HPC market has by no means been large enough 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 Might Hold 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 in brief provide. A priority is that the superior buying energy of hyperscalers—the largest clients for GPUs—might make it troublesome for Nvidia, AMD and others to justify accepting orders from the HPC group.
- Stress to Overbuy GPUs. Some HPC information heart administrators, particularly within the authorities sector, advised us that AI “hype” is so robust that their proposals for next-generation supercomputers needed to be replete with mentions of AI. This later pressured them to observe by means of and purchase extra GPUs—and fewer CPUs—that their person group wanted.
- Problem Negotiating System Costs. Multiple HPC information heart director reported that, given the GPU scarcity and the superior buying energy of hyperscalers, distributors of GPU-centric HPC techniques have develop into reluctant to enter into customary worth negotiations with them.
- Persevering with Availability of FP64. Some HPC information heart administrators say they’ve been unable to get assurance that FP64 models shall be accessible 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 creating good algorithms and software program emulators geared toward producing FP64-like outcomes run at decrease or blended precision.
Preliminary Conclusion
It’s early within the sport 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 development. HPC customers in authorities and tutorial settings are transferring full velocity forward with AI analysis and innovation, whereas HPC-reliant industrial corporations are predictably extra cautious however have already got functions in thoughts. Oil and fuel majors, for instance, are beginning to apply AI in different power analysis. The airline trade tells us AI gained’t change pilots within the foreseeable future, however with at present’s world pilot scarcity, some cockpit duties can in all probability be safely offloaded to AI. There are some actual considerations as famous above, however most HPC group members we discuss with consider that the HPC-AI convergence is inevitable, it’s going to deliver advantages and the HPC group will adapt to this shift because it has to prior transitions.
