Live notes from the HPC-AI Advisory Council 8th Annual UK Conference, Mattioli Woods Welford Road Stadium, Leicester, 13–14 October 2026. Updated through the day; day 2 is here.

09:30 Introduction

Conference Introduction and Overview — Brian Sparks (HPCAIC), Mark Wilkinson (DiRAC)

Our conference theme for 2026 is “HPC-AI: From marketing to reality: What Works; What doesn’t; What’s Next?”

Interestingly, this image is generated by ChatGPT, which assures us the headlines are correct.

09:40 UK-LLM

UK-LLM and a Path Towards Frontier-level Open Source Artificial Intelligence — Pontus Stenetorp (University College London)

The most important innovation is language, so I’m not surprised intelligence comes from text.

Units of innovation:

  1. Pre-training: ~$100 million.
    • Some interesting research questions can only be asked at this phase.
    • No moat, only trade secrets.
  2. Fine-tuning.

Their first model was not much of an innovation but a demonstration, except for one thing: using its own generated text to fine-tune itself. They haven’t published this, and it has since become a standard part of training.

The curse of multilinguality: training on 2 languages is worse than training on 1. Cross entropy turns training into classification, and with more to classify, the model loses interest.

English superiority: models do better if prompted in English. The idea is then to translate text into English first and train on that. The problem is that translation has “translationese”, so the quality is lowered. It turns out that training purely on translated text performs almost as well. Their comparison of English vs. English+French shows they “solved” the curse of multilinguality.

Barriers of intelligence: e.g. 7B seems to be the barrier to “think” well.

The decision with students: all of you can be first authors of a paper, or have a ton of compute (UK-LLM, SOFAIR, …).

OSAI Working Group. The Open Source AI Definition:

  • does not require you to release the training data, only to describe it;
  • their aim is to release with ethical training data, stricter than OSAI requires;
  • is not the same as open source software;
  • comes in degrees of openness.

Why release the data?

  • E.g. generalization: without the training source, you can’t tell how out of sample something is.
  • E.g. the Hugging Face incident: why can’t we investigate what happened the way we treat a plane crash?
  • E.g. Kimi K3 on local hardware: it would be even greater for a truly transparent model.

Isambard-AI as a full machine is 46 million GPUh/yr; a frontier LLM takes ~20–40 million GPUh.

Sovereign is not isolated, hence the Global Open Source AI Summit.

On the £750 million investment for inference only: we need investment for training as well, otherwise he can move and give up training in the UK.

Question from meeting him afterwards:

He mentioned that the UK government is not investing in LLMs correctly. So I followed up, saying it seems like in the last few years AI research has only been possible in private companies, and the natural question to ask is why not found one. His answer primarily lies in the key criterion he wants to have: open training data. A private company will not allow that, because in reality if you have money and people see that in the training data, companies will sue (he quoted the copyright article on Wikipedia mentioning Mickey Mouse), and hence the only way to do it is to have no money worth suing for. The Global Open Source AI Summit he mentioned has even thought of setting up two companies, one in the most liberal country, while the other holds the money, compute, etc., and basically prepared to get sued.

10:35 Isambard-AI

Isambard-AI’s Early Years and Future Roadmap: Driving Open and Sovereign Supercomputing — Sadaf Alam, Richard Gilham, Ashish Tom, Jake Watson (Bristol Centre for Supercomputing (BriCS), University of Bristol)

  • 5,448 GH200
  • ~5,000 users
  • AIRR Portal, built on Waldur
  • Kubernetes on Slingshot: vLLM containers work at near bare-metal performance

Rise of the agents:

AI Agents could turn all users into superusers, but only if they do…

There should have been a pun intended here: superusers? Agents on the loose?

Agentic Ops: https://skills.isambard.ac.uk. What is this? It redirected to docs.isambard.ac.uk for me.

Low volume of support tickets: ~100–120 tickets per month.

Catching up with Rich afterwards:

  • There are many signs users are running coding agents.
  • They are getting things done, but causing so many problems: running on login nodes, etc.
  • Compared to before coding agents: different, not better or worse.

11:40 BeeGFS

BeeGFS High-Performance Storage Software, Sovereign by Design — Dominic McKendry (BeeGFS)

BeeOND: BeeGFS On Demand.

A case study: a university in Germany thought they could buy 1.5 PB of NVMe storage, which is not possible anymore. Instead: 300 TB of SSDs + old HDDs.

S3 objects.

Slide: BeeOND scratch filesystem. The local NVMe of each job node is pooled into a job-native scratch tier, staged in from and out to global storage (BeeGFS, Lustre, Ceph, VAST, Weka, Spectrum Scale) with BeeGFS Copy.

  • In userspace
  • Deployed in minutes
  • Software-defined

12:00 Data-driven force fields

Data-Driven Force Field Development for Biomolecular Simulation — Daniel Cole (Newcastle University)

Biomolecular systems are heterogeneous, span wide spatial and time scales, and are sensitive to small differences in energy.

Molecular mechanics:

Slide: Force Field. The molecular mechanics energy as a sum of bonded terms (bonds, angles, torsions) and non-bonded terms (Lennard-Jones and Coulomb), with a protein structure.

Open Force Field (OpenFF)

Slide: Machine Learning Interatomic Potentials. The energy of an atom written as a sum over body-ordered contributions; an atom is represented by its neighbourhood density, and a model is trained to reproduce quantum mechanical energies and forces.

His blog and group on GitHub.

12:30 The venture scientist

The Venture Scientist and the Compute Layer: What HPC-AI Unlocks for Science Founders — Riam Kanso (ConceptionX)

  • Not every PhD will end up in an academic position.
  • The funding model: in the future, some of these successful companies can fund the next generations.

Slide: We discover and back Venture Scientists: researchers who found companies from their own scientific work. 700+ PhD researchers backed, 200+ science companies founded, 90+ partner universities, 15 countries, £1B+ portfolio value.

There is no obligation to found a company; it could be two chapters in the dissertation.

  • This changes what % of people would consider founding a company.
  • Compute is important for founding scientists:
    • validation speed
    • what can be built
    • who can build it

Case studies:

  • QMatter
  • Mater-AI: 7 out of 9 AI-generated materials successfully replicated in the lab

What do they have in common?

  1. Insight first
  2. Proof is the currency
  3. Small teams, big science

It is between a few of them going through to a professorship, or most of them working for large corporations.

Researchers lose compute when they need it most

They provide training like a “Deep tech MBA”.

I asked whether she worries these newly founded companies might be acqui-hired by big companies, and whether that would impair her vision.

She said no, the value is in the creation of these companies, even if the founders eventually still end up working for big companies. It is still better than getting there directly and working there for the rest of their lives.

13:00 Lunch

14:00 Credibility of quantum computers

Credibility of Real-World Quantum Computers and Simulators — Animesh Datta (Warwick University)

Mission 1

By 2035, there will be accessible, UK-based quantum computers capable of running 1 trillion operations and supporting applications that provide benefits well in excess of classical supercomputers across key sectors of the economy.

From the UK’s National Quantum Strategy Missions.

  • Quantum 1.0: single-particle quantum mechanics
  • Quantum 2.0: many-particle quantum mechanics

Slide: Quantum computer. Block diagram of a quantum chipset in a refrigerated enclosure, controlled by a classical computer. Inputs and outputs are classical bit strings; probability distributions of classical bit strings; randomness in quantum measurements.

He pointed to Quantum Algorithms (Dalzell et al., Cambridge University Press, 2025).

Slide: Credibility question. Is the output of my quantum computer correct? Solving the wrong problem (validation), implementing the wrong programme (verification), uncertainties in the model (UQ), and hardware noisy and imperfect even after error correction. Errors: classical about 1e-16 per gate, quantum about 1e-2 per gate.

Integer factoring can be verified easily. But not all problems are like this, e.g. differential equations, optimization, etc.

Slide: Inspiration: Interactive proofs. Build easy trap computations similar to the hard target computation, run both on the same hardware, check the correctness of the traps, and bound the distance between the ideal and actual output.

Interactive proofs: establish traps to bound the target.

14:40 The HPC Hardware Lab

The HPC Hardware Lab — Alastair Basden (DiRAC / Durham University)

Interesting to see: SSH by day, Slurm by night.

They mentioned SHAREing here, a UKRI Digital Research Infrastructure project that provides performance and machine assessments to the UK computational science community.

15:00 NFCS roadmap

Connect, Coordinate, Collaborate - The NFCS Roadmap for Federation — Jon Hays (Queen Mary University of London)

National Federated Compute Services.

Slide: Synthesising Recommendations. 26 flexible-funded projects, 259 recommendations received, 6 themes, 17 umbrella recommendations. Themes: federated access and orchestration; data movement and access; software, AI and emerging platforms; governance, cybersecurity and data contracts; community, skills and support; sustainability and fair allocation.

Programmatic access by AI
access to resources, data, tools

15:20 DRI ecosystems

Evolving Digital Research Infrastructure Ecosystems: A Metascience Perspective — Louise Chisholm (UK SKA Regional Centre / UCL)

Slide: Impact is created by an ecosystem, not a stack. On the left, the stack of components of the UK SKA Regional Centre; on the right, the ecosystem in context: impact, infrastructure, incentives, governance, policy, data, storage, compute, funding, researchers, publications, and more.

Slide: Metascience helps us understand and improve research systems, by applying scientific methods to how research systems operate: how DRI facilities and services are co-designed and delivered, how their impact can be maximised, and how they contribute to institutional and national priorities.

Related to, but not the same as, Thomas Kuhn’s idea.

15:40 AI predictive maintenance

AI-Driven Predictive Maintenance and Foundation Models for Sustainable and Cost-efficient HPC Systems — Erick Sperandio Nascimento (University of Surrey)

Slide: Relevance of AI for HPC Systems: Review. A bar chart of publications per year from 2011 to 2021, peaking at 9 in 2019. Gaps still relevant nowadays: limited sensor data, over-reliance on log data, maintenance history not integrated, lack of remaining useful life prediction.

Downtime cost: ~$9k/min.

16:00 Coffee

16:25 Integrated HPC+AI systems

Towards an Accelerated Tomorrow – Planning for Integrated HPC+AI Systems of The Future — Chris Derson (Fsas Technologies)

Slide: CXL memory utilization (V2, V3). CXL 2.0 allows CXL memory to be used by different servers (memory pooling); CXL 3.0/3.1 servers can work together on shared memory (memory sharing). Diagrams of memory pool and memory sharing concepts over a CXL fabric.

What’s CXL? Digesting it with a ChatGPT session: like a network-attached memory pool that eliminates as many middlemen as possible:

something between NUMA and RDMA: a memory fabric that enables load/store access across a larger physical system, without automatically providing the global addressing and coherence semantics of a single SMP machine.

Slide: Fujitsu 3D Many Core architecture. A 2nm core die stacked on a 5nm SRAM die through TSV, around an IO die on a silicon interposer; the costly 2nm process is limited to less than 30% of the area. Balancing performance, power efficiency, and cost.

ChatGPT digestion:

Fujitsu’s 3D many-core architecture is most comparable to AMD’s second-generation 3D V-Cache, while its broader chiplet integration strategy resembles AMD’s MI300 and TSMC’s SoIC + CoWoS technologies. Designed for the FUJITSU-MONAKA Arm processor, on sale from November 2026, the architecture stacks 2nm compute dies on 5nm SRAM dies and integrates multiple chiplets through a silicon interposer. Rather than introducing fundamentally new packaging technology, Fujitsu differentiates itself by combining established 3D stacking and heterogeneous integration techniques to optimize CPU performance, power efficiency, and manufacturing cost.

They mentioned patched llama.cpp, vLLM, etc. running faster on Arm.

Is this related to the Arm HPC system in Japan by Fujitsu that once held the top spot in the TOP500 for a while? Yes: that is Fugaku, built on Fujitsu’s A64FX, #1 on the TOP500 from June 2020 to November 2021. MONAKA is its successor line, and a variant of it, MONAKA-X, is planned for FugakuNEXT.

17:15 Day 1 endnote

Day 1 Endnote: TBD — David Barber (SOFAIR)

Science of Fundamental AI: A UK AI Research Lab.

Slide: Best Frontier Models, a leaderboard. The top seven, led by GPT-6 and Claude models, are closed and from the US; the next three, Kimi K3, GLM-5.3 and DeepSeek V4, are open and from China.

  • Best models: closed, US.
  • Next best: open, PRC.

Reliable Access to Reliable Models.

All frontier open models are MoE now.

AI for Science? → Science for AI: bring different sciences to the table to build better AI.

Slide: SOFAIR Vision. Novel architectures (statistics, mathematics, neuroscience, computer science); distributed training (train across the world, unite 1000s of GPUs, train large-scale models); open source (bring the global open source community together, build the best open source models). Supported by 40 postdoctoral researchers and 10 PhD students.

The idea: decentralised training.

UK AI Grid:

  • Zenith
  • Dawn
  • Isambard

Slide: Vanilla distributed data parallelism (DDP) next to vanilla federated averaging, as algorithms. Federated training adds an inner loop of K local steps on each client before the server update.

Slide: Basic wide-area distributed training as bi-level optimisation: choose the inner optimiser, outer optimiser and local interval K. Open questions: which optimiser states to share and when (DES-LOC), preserving global memory while responding to local updates (MT-DAO), compressing the stored and communicated state (LoRDO).

Slide: Feasibility Analysis: Training Time (Days). 10B model on 384 GPUs: DDP at 100 Gb/s on 1 site takes 0.7 days, Photon at 10 Gb/s across 4 sites 0.9 days. 100B model: DDP 72.9 days, Photon 78.4 days.

So training across sites doesn’t increase the wallclock time much.

Faster attention:

  • Flash attention is solving the issue via hardware.
  • Sparse attention: cf. “A survey of transformers”. The “needle in a haystack” isn’t addressed by these kinds of approaches.
  • Bidirectional…
  • Hidden layer: lower rank?
  • Recurrent encoding: sort of like a Kalman filter.
  • Mamba is one row in the table comparing the alternatives.

We have plenty of ideas (for faster attention), but the main difficulty may be demonstrating them at scale.

Audience Q: the French have a SOTA model, why don’t we?

A: The French are more protectionist than the UK.

It seems like people in the UK government are negative and say “we can’t do it”, but the speaker thinks we actually can.

SSMs like Mamba scale like O(K^2).
