Compressing AI Models at GPT Scale

Wouldn't it be great to run models with 10-100 Billions of parameters locally, on your laptop / phone

Every conference needs a bit of chaos, at #ASHPC25 we decided to go with quantum chaos and a keynote by Jan Šuntajs (IJS) on

High performance computing #HPC at the boundaries of quantum chaos

Why? – #AI answers: "It reveals deep rules of nature and helps us build better quantum technologies."

Yesterday at #ASHPC25 we shared the latest update on the state of MUSICA #supercomputer ⤵️
claudiablaas.bsky.social Claudia Blaas-Schenner @claudiablaas.bsky.social · May 22
MUSICA is not an #HPC system that can sing and dance, it‘s:

MUlti-SIte Computer Austria

Infrastructure
--> power & cooling

Delayed delivery

Acceptance
--> almost all GPUs had to have their thermal transfer pads replaced
--> Weka storage needs better CPUs (will be exchanged with 64 core versions)
MUSICA - MUlti-SIte Computer Austria MUSICA - power distribution MUSICA - first rack & plumbing MUSICA - GPU re-padding

Opening keynote at #ASHPC25 by Erwin Laure (TUM & MPCDF) on „HPC & AI - Competition or Collaboration“.

HPC is not driving the chip market – AI does!

How to adopt? Use mixed precision or emulation (#Ozaki scheme, more info in the thread)

Key insights – #HPC is dwarfed by #AI

👉 Al is here to stay
👉 Hardware market driven by Al
👉 Impact of Al on scientific methods still somewhat open – but great potential

🧵
Erwin Laure (TUM & MPCDF) on „HPC & AI - Competition or Collaboration“ at ASHPC25 KEY INSIGHTS: FUTURE AI/HPC ARCHITECTURES —> Divergence vs. Integration? HPC remains unique due to precision and storage. Al brings low-precision inference and training demands-opportunities arise at the intersection. —> Opportunities for Innovation Most innovation expected on the software stack, while hardware is vendor-driven. Emulating FP64, edge computing, and chiplet ecosystems were highlighted. —> Portability & Sharing Emphasis on portability across platforms - especially for hybrid HPC+Al environments. —> Operational Shifts Agents and inference are shaping new operational paradigms - we should form a working group. —> Global Coordination Strong sentiment: balance industrial Al trends and scientific HPC needs. Erwin Laure (TUM & MPCDF) on „HPC & AI - Competition or Collaboration“ at ASHPC25 KEY INSIGHTS: CODE GENERATION, PRECISION, DEBUGGING —> Al Helps LLMs assist well with simple tasks and boilerplate code; fail more often on complex, hybrid, or algorithmic logic. —> Prompting Programming Prompt engineering seen as inadequate pedagogy. Better for experienced developers no replacement for formal programming education. —> Trust & Validation Consensus on the need for (more) robust test harnesses (unit tests, integration) practices for validation. —> Scientific Intuition (current) Al lacks intuition; safe precision reduction must remain scientists‘ decision with proper validation and testing. —> Path Forward (FAST!) International repositories (e.g., prompt libraries, agent systems) and shared fine-tuned contexts. Erwin Laure (TUM & MPCDF) on „HPC & AI - Competition or Collaboration“ at ASHPC25 KEY INSIGHTS: DATA CURATION & GENERATION —> Data Complexity Problem Each community has unique formats. There is a great need for Al to help make scientific data available for training. —> Local Storage (a key difference in AI/HPC platforms) Supercomputing centers could support in-situ Al processing before discarding intermediate data. —> Workflow Innovation Need for shared pipelines to load, preprocess, and stream data — especially for large GenAl models. —> Access Social and political barriers limit data access. This is difficult. We must continue to improve. Some fields (e.g., structural biology) are ahead; others lag behind. —> Future Clear plan for improving, not just talking about, scientific data for Al. Erwin Laure (TUM & MPCDF) on „HPC & AI - Competition or Collaboration“ at ASHPC25 KEY INSIGHTS: GENAI FOR SCIENCE (IS AI IMPROVING SCIENTIFIC PROGRESS?) —> Impact Metrics Track time to discovery, scientific output, human effort saved, community uptake, and cross-disciplinary impact. Use both quantitative (e.g., citations, speedups) and qualitative (e.g., novelty, utility) measures. —> Practical Benefits GenAl is best at supporting tedious, complex, or repetitive tasks like literature review, hypothesis generation, debugging, and code maintenance - freeing up human creativity. —> ModSim vs Al GenAl can enable science in data-rich domains (e.g., astrophysics, protein folding) and assist where first-principle models fall short. —> Best Practices Avoid biases (e.g., cherry-picking, weak baselines) via provenance tracking, peer review, and international frameworks. —> Global Collaboration 1000 Scientist Jam - repeated in many places. Build *REAL* experience. Foster trust through transparency an reproducibility.
