Welcome to the third entry on this sequence on AI. The first one was an introduction and sequence overview and the subsequent mentioned the aspirational purpose of synthetic normal intelligence, AGI. Now it’s time to zero in on one other well timed subject—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 around the globe. As I mentioned within the intro column, the sequence doesn’t goal to be definitive. The purpose is to put out a variety of present data 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 [email protected].
AI Depends Closely on HPC Infrastructure and Expertise
HPC and AI are symbiotes, creations locked in a decent, mutually useful relationship. Each stay on the same, HPC-derived infrastructure and frequently change advances—siblings sustaining shut contact.
- HPC infrastructure permits the AI group to develop subtle algorithms and fashions, speed up coaching and carry out fast 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 nicely past primary interprocessor communication.

- However HPC’s best present to AI is many years of expertise with parallelism—particularly helpful now that Moore’s Regulation-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 improvement duties are. He mentioned: “Not a lot. The rules 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 gas the expansion of the mainstream AI market—whilst different gifted folks stayed put to advance modern, “frontier AI” inside the HPC group.
HPC and Hyperscale AI: The Information Distinction
Social media giants and different hyperscalers have been in a pure place to get the AI ball rolling in a severe approach. They’d numerous available buyer knowledge for exploiting AI. In sharp distinction, some economically vital HPC domains, resembling healthcare, nonetheless battle to gather sufficient usable, high-quality knowledge 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 knowledge sources and experience to use frontier AI. The Optum collaborators now have entry to usable (deidentified, HIPAA-compliant) knowledge on greater than 300 million sufferers and medical enrollees. An vital goal is for HPC and AI to associate in precision drugs, by making it attainable to shortly sift by tens of millions of archived affected person data to determine remedies which have had the very best success for sufferers intently resembling the affected person underneath investigation.

The pharmaceutical business additionally has a scarcity of usable knowledge for some vital functions. One pharma exec informed me that the availability of usable, high-quality knowledge is “miniscule” in contrast with what’s actually wanted for precision drugs analysis. The info scarcity challenge extends to different economically vital HPC-AI domains, resembling manufacturing. Right here, the scarcity of usable knowledge could also be attributable to isolation in knowledge silos (e.g., provide chains), lack of standardization, or easy shortage.
This may have penalties for all the pieces from HPC-supported product improvement to predictive upkeep and high quality management.
Addressing the Information Scarcity
The HPC-AI group is working to treatment the info scarcity in a number of methods:
- A rising ecosystem of organizations is creating sensible artificial knowledge, which guarantees to develop knowledge availability whereas offering higher privateness safety and avoidance of bias.
- The group is creating higher inferencing—guessing capacity. Larger inferencing “brains” ought to produce desired fashions and options with much less coaching knowledge. 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 could be achieved with smaller, less-generalized (extra domain-specific) fashions that require much less coaching knowledge—together with much less time, cash and power use. Some specialists argue that a number of small language fashions (SLMs) are prone to be more practical than one massive language mannequin (LLM).
Useful Convergence or Scary Collision?
Attitudes of HPC middle administrators and main customers towards the HPC-AI convergence differ drastically. All count on mainstream AI to have a robust influence 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 useful 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 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 purpose for concern, though HPC customers have needed to flip to mainstream IT markets for expertise up to now. As somebody identified in 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 Could Preserve Optimists and Pessimists Up at Evening
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 most important prospects for GPUs—might make it tough for Nvidia, AMD and others to justify accepting orders from the HPC group.
- Strain to Overbuy GPUs. Some HPC knowledge 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 comply with by and purchase extra GPUs—and fewer CPUs—that their person group wanted.
- Issue Negotiating System Costs. A couple of HPC knowledge middle director reported that, given the GPU scarcity and the superior buying energy of hyperscalers, distributors of GPU-centric HPC techniques have change into reluctant to enter into customary worth negotiations with them.
- Persevering with Availability of FP64. Some HPC knowledge middle 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 aimed 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 educational 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 various power analysis. The airline business tells us AI gained’t exchange pilots within the foreseeable future, however with at this time’s international pilot scarcity some cockpit duties can in all probability be safely offloaded to AI. There are some actual issues as famous above, however most HPC group members we speak with imagine that the HPC-AI convergence is inevitable, it should carry advantages and the HPC group will adapt to this shift because it has to prior transitions.
