18. CERN IT Data Centre Compute & Storage Procurement Towards LHC Run 4: Challenges and Community Perspectives

Luca Atzori (CERN)

Techwatch (Topical Session)

As CERN prepares its central IT Data Centres for the High‑Luminosity LHC era (Run 4), the compute and storage infrastructure operated by CERN IT must evolve to meet significantly higher demands in throughput, capacity, and efficiency while remaining within strict constraints on budget, power consumption, and operational simplicity. With LS3 expected to begin in July 2026 and the HL‑LHC start...

39. Fujifilm’s Evolution of Magnetic Tape: BaFe and SrFe Innovations for Next-Generation HPC Storage

Ms Elisabeth Gameiro (FUJIFILM Recording Media France)

Techwatch (Topical Session)

High-Performance Computing (HPC) has become a critical tool in scientific research, engineering, AI training, and more. Some of the main challenges of HPC in data storage are handling massive data volumes, ensuring long-term data integrity and security, reducing the floor space and the carbon footprint.

HPC applications generate petabytes of data, requiring high-capacity storage solutions....

30. GPU deployment at KIT

Matthias Jochen Schnepf

Techwatch (Topical Session)

GPUs are energy-efficient hardware for several High Energy Physics (HEP) applications.
However, servers with GPUs are expensive and special in cooling, operation, and software support compared to CPU-only servers.
We present what we have learned during the operations of GPU servers regarding these aspects at KIT, as well as some experiences from other sites.

22. HEPiX Technology Watch Working Group Report

Mr Andrea Chierici (Universita e INFN, Bologna (IT)), Dr Andrea Sciabà (CERN)

Techwatch (Topical Session)

The Technology Watch Working Group, established in 2018 to take a close look at the evolution of the technology relevant to HEP computing, has resumed its activities after a long pause. In this report, we provide an overview of the hardware technology landscape and some recent developments, highlighting the impact on the HEP computing community, with a special focus on resource price evolution.

13. Tape Technology evolution update from the CERN perspective

Vladimir Bahyl (CERN)

Techwatch (Topical Session)

This talk is a short update on the recent evolution of the tape technology from the CERN user perspective.

4. Technology Watch: A broad view on cooling

Tristan Suerink

Techwatch (Topical Session)

With CPU’s and Accelerators that want to have more and more watt compared with the previous generations, cooling will become getting harder to keep future clusters running efficiently.
At every conference, you’ll see more companies telling you that they have the real golden egg for this problem. The big question is, do they really have that golden egg for you?
We will show the different type...

5. The future of cooling @ Nikhef

Tristan Suerink

Techwatch (Topical Session)

The problem of efficient and effective cooling has been haunting us for nearly a decade: since 2018 Nikhef has been aware of the issue and has explored several possibilities: ones that fir our environment, use the data centre infrastructure we have, and the infrastructure we have for getting rid of residual heat.
But what is the best technology out there today? And which technologies that...

26. WLCG Workshop on Heterogeneous Architectures Summary

Oxana Smirnova (Lund University)

Techwatch (Topical Session)

The WLCG Workshop on Heterogeneous Architectures (CERN, Dec 2025) reviewed the readiness of GPU‑enabled workflows across LHC experiments and the requirements for heterogeneous resources ahead of Run 4. While GPU acceleration is advancing in simulation, reconstruction and ML workflows, experiments are not yet ready to request formal GPU pledges, pending further benchmarking, workflow...
