First in the UK, second in the world!

We’ve retained our @WorldUniRanking for the third year in a row! 🎉

This success is thanks to every single member of Imperial’s community, as we work together to make a meaningful difference in the world.

@Sh1nj1_kor Ποια η γνώμη σου για το value for money ratio του DeepSeek V4 PRO σε max setting? Τον έχεις δοκιμάσει; Θεωρώ ότι είναι ένα υπερβολικά οικονομικό alternative.

HUAWEI has unveiled the Tau (τ) Scaling Law, a new principle guiding the evolution of both semiconductors and electronic systems, which is expected to deliver transistor density equivalent to 14 Å (1.4 nm) processes in high-end chips by 2031.

What is LogicFolding? For circuit design, it aggressively compresses propagation time between adjacent flip-flops, tightens critical path & enables chips to run faster. HUAWEI high-end chips are expected to feature transistor density equivalent to 14 Å (1.4 nm) processes by 2031.

[Nick Brown @NickBrownHPC]

I am advertising for a fully funded 3.5 year PhD (with enhanced yearly stipend) exploring accelerating HPC algorithms on AI accelerators such as including @cerebras and @tenstorrent . @EPCCed is the UK national supercomputing centre, lots of exciting things going on!

@Sh_Cl_Pod Το αξίζετε! All the best!

Agentic coding is the real computation/communication overlap for hiding the latency of the modern #HPC engineer.

March was my last month at @imperialcollege where I spent the previous 6 years and 6 months (since October 2018). I am grateful to have completed a PhD and worked as a Post-Doc Researcher at this institution.

[George Bisbas @GeorgeBisbas]

Additionally, I was fortunate to work alongside Navjot Kukreja, @Louboutjunior, Rhodri Nelson, Edward Caunt, and Zoe Leibowitz around the https://t.co/pt102lh4Kw, as well as many other researchers from academia and industry.

5/5
Our work impacts industry-relevant applications in various fields, including seismic imaging, medical ultrasound, and CFD. We evaluated the strong and weak scaling of four wave propagators of industrial interest (Isotropic Acoustic, Anisotropic Acoustic (TTI), Isotropic Elastic with and without viscosity) across CPU (16384 CPU cores) and GPU clusters (128 A100s).

💻 All the code and benchmarks are #opensource and available online. Get in touch for questions and interesting discussions!

See you in Milan! 😉

4/5

🔑 Key contributions from our work include:

👉 Automated MPI-X code generation, where X is any of the target languages Devito supports (e.g., OpenMP, OpenACC, or CUDA/HIP/SYCL in the case of DevitoPRO).

👉 Multiple computation-communication strategies.

👉 An MPI-aware backend for distributed NumPy arrays for seamless domain decomposition. The data is physically distributed, but from the user's perspective, it remains a logically centralized entity.

After 6 years of service the Isambard 2 supercomputer is finally being retired! Starting in May 2018, Isambard was the world's first production Arm-based supercomputer, employing ThunderX2 CPUs. Isambard 3 takes over today using NVIDIA Grace Arm-based CPUs provided by HPE
