Our session on #ai for #hpc at #pasc26 continues with @ncar-ucar.bsky.social 's Monica Morrison exploring tension between #ai capability and the responsible & ethical side. Many in the audience are not optimistic, and think in the short term advancing capability will dominate

Ben Shipway, head of dynamics research group @metoffice.gov.uk and leader of scientific development of LFRic kicks off the #pasc26 mini symposium on #AI and #HPC, plan is will replace physics models for some parts of the system but need to keep an eye on the details

Albert Reuther gives a great talk at #HPCDays about #hpc at #mit #llsc, explaining how user behaviour has driven their interests and more generally with potentially some of the first interactive computing happening way back when in the lab

Durham HPC Days 2026 (15–19 June) will bring together researchers, developers, and practitioners to explore the frontiers of HPC, data analysis & scientific innovation. Look out for EPCC colleagues across the programme: edin.ac/4xdODIE

Rich Neale, my @epcc.bsky.social PhD student, has a poster today at #RISCVSummit exploring ET-SoC-1 for #hpc and exploring what the term "transputer" means wrt modern architectures. Thanks to #Ainekk0 for access to the hardware, some really interesting early performance PDE solver results

Last year the #riscv #HPC SIG published a gap analysis, with #lustre parallel file system a high priority. #openchip picked this up and have done a fantastic job getting #riscv support upstreamed in #lustre. Really nice summary at #RISCVSummit, showcasing ecosystem progress

Really interesting talks by Yiftach from @nextsilicon.com about the Arbel #riscv core and wider plan for large core count CPU at #RISCVSummit . He even had a physical Arbel-based CPU with him to show.

Interesting @riscv.org.web.brid.gy summit so far, a buzz around server grade #riscv CPUs. Been a bit of an RVA23 hardware winter recently, but concrete vendor announcements this week feel like good progress is being made towards 2026 high performance hardware

Our paper "Lifting to tensors when compiling scientific computing workloads for AI Engines" presented at #CCGrid today, a compiler flow for #AMD #AIE which lifts Fortran+OpenMP to tensors & then leverages for efficient execution on the #NPU. arxiv.org/pdf/2605.03566

#CCGrid in Sydney starts today, exciting technical programme ahead this week exploring intersection of #HPC, cloud and edge. My highlight so far is seeing a kangaroo for the first time 😀

Great to see #xDSL featured on @github.com's maintainers month. Starting life as an #ExCALIBUR project led by Tobias Grosser, it has an active research & industry userbase and is a really useful framework for compiler development. maintainermonth.github.com/academia/xds...

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 @cerebrassystems.bsky.social and @tenstorrent.bsky.social . Come join @epcc.bsky.social, the UK national supercomputing centre.

@epcc.bsky.social 's David Henty explores performance comparison at #CUG for minikab cg benchmark. Comparing ARCHER2 (AMD zen2, Slingshot 10) vs Cirrus (AMD zen5, Slingshot 11). Newer machine around 3.5 times faster per node

The French Riviera is a great location for #CrayUserGroup this year. Interesting first day of tutorials and bofs, and was a pleasure to introduce @epcc.bsky.social 's #AI factory antenna and good discussions in the session about the role of #AI more generally

We will host a @vi-hps.mast.hpc.social.ap.brid.gy in about a month. Would be great to see a wide variety of communities. The workshop is, as always, organised in collaboration with the performance analysis tool developers themselves under the umbrella of the HAI-End / @shareing.bsky.social

It was an honour today to give a keynote at the #XuanTie #RISCV community conference in Shanghai. Talking about #hpc , the importance of the c920 and some early benchmarking of their latest c950 which looks like an impressive @riscv.org.web.brid.gy capability

The best thing about travelling into central Shanghai from the airport is that it's a great excuse to ride the maglev

Excited our paper on stencil compiler for @cerebrassystems.bsky.social #WSE has been accepted to ASPLOS . Using MLIR, without any code changes across three frontends we have highly competative performance against manually written code and around 14x performance of 128 A100 GPUs.

Recurring theme of @hipeac.bsky.social this week has been the intersection of compilers and architectures to address challenges in #ai, especially llm. Really exciting when @jocare.bsky.social announced #HiPEAC 2027 will be held in Glasgow!

In Krakow this week for @hipeac.bsky.social , Teresa from #BSC kicking off the #RISCV for #HPC workshop, a day of interesting talks and discussions

My PhD student Gabriel had a busy time at #SC25 and has written up his experiences, especially presenting a couple of papers leveraging #MLIR for #FPGAs. One at the LLVM workshop on a Fortran+OpenMP flow for #Xilinx #FPGAs and another at H2RC workshop on a Fortran intrinsics flow for AI engines

There are lots of exciting #HPC and #AI projects going on at @epcc.bsky.social , with quite a few more to start in 2026. Come join us!

Thanks @kieranleach.bsky.social for doing a great tour of the @epcc.bsky.social #ACF facility for Christian from @unipaderborn.bsky.social and @stevenwright.bsky.social from @yorkuniversity.bsky.social. I always learn a lot from these, and was great to see the new #Cirrus on its 1st day of service

Many congratulations to my @epcc.bsky.social PhD student Mark Klaisoongnoen who passed his PhD viva today! Exploring accelerating financial workloads on #FPGAs, Mark researched techniques for improving performance & energy efficiency. The U280 was a prop only, he doesn't get to keep it ;)

Nick Brown from @epcc.bsky.social is up now.

Attending #CIUK25? Our colleagues are looking forward to meeting you! Find us at the stands for ARCHER2-Cirrus and the CAKE Network Plus. EPCC at #CIUK2025:https://edin.ac/4pR8dpL

Very cool, a home made Motorola 68k system on breadboard with 512KB of RAM and booting Linux from ROM. Hooked up and specialised by Jeremy Cohen from Imperial based on design by Steve Chamberlin. Running Linux to play Colossal Cave Adventure over uart

It's our last day at #SC25! @nickbrown-hpc.bsky.social and Gabriel Rodriguez-Canal will present their paper 'Programmer productivity and performance on AMD's AI Engines: Offloading Fortran intrinsics via MLIR a case-study'. Find them in 263-264 at 9:38am CST.

Well-done to my PhD student Gabriel Rodriguez-Canal @epcc.bsky.social who gave a great talk about our work support Fortran intrinsics on #AMD #AIEs at #SC25 #H2RC. The first step in #AIE Fortran support. dl.acm.org/doi/pdf/10.114…

Fascinating talk by Ilan Tayari from @nextsilicon.com at #SC25 #H2RC about Maverick 2. Based on dataflow help solving the issue with traditional architectures around (very) low ALU occupancy, their architecture will move #HPC away from Von Neumann architecture

I really enjoyed chairing the panel on an open #HPC ecosystem at #SC25 Thanks to @fclc.bsky.social from @tenstorrent.bsky.social , Teresa from @bsc-cns.bsky.social, Tony from #Redhat, Daniele from #E4computer-engineering and Penporn from @developers.google.com

Was really great to meet @jeffgeerling.com at the @epcc.bsky.social booth at #SC25, we had a fascinating chat and I was really inspiring to hear about some of Jeff's projects and activities. Also really cool to chat with him about our Raspberry PI mini supercomputer #WeeArchie

It's going to be great catching up with lots of #HPC people next week at #SC25 . #Supercomputing is always a busy week, I wrote up some of the activities I am involved in www.epcc.ed.ac.uk/whats-happen...

Thanks @riscv.org.web.brid.gy for the invite to give a keynote at #RISCVSummit a couple of weeks ago. We have seen great progress in #RISCV for #HPC, and given promises by vendors and progress in the sw ecosystem I predict that 2026 could be a watershed year. youtu.be/ItA-NS4vxsU?...

The dev zone at #RISCVSummit was crammed full of interesting things and very popular this week, here I chat to Austin @riscv.org.web.brid.gy about the #HPC #RISCV demo we had brought from @epcc.bsky.social . Thanks to Carl for providing the hardware and installing things!

Had a great time at the #RISCVSummit 2025, thanks very much to @riscv.org.web.brid.gy for the invitation to give a keynote about #RISCV in #HPC, was an honour and I also very much enjoyed being a panelist at the #Google breakfast and presenting #HPC #RISCV updates during the member's day

Very glad to be down south at the DRI congress in Leeds and to learn about the UK's Digital Research Infrastructure. And thanks to Garth Wells (EPSRC) to flag CAKE! www.cake.ac.uk

Nick presents our CAKE @cake-dri.bsky.social project at the #HPC #AI conference in Leicester.

EPCC has won EU & UK Gov funding to establish and operate the €10m (£8.6m) UK AI Factory Antenna. This initiative will help organisations increase literacy in the technology and its use, and show how it can help increase productivity and deliver growth. edin.ac/3WzDaSx

I wondered if one could write a @tenstorrent.bsky.social #Wormhole simulator that will execute tt-metal binaries based on the information in the excellent ISA documentation. Answer is yes, tt-sim is a Python @tenstorrent.bsky.social simulator. Still WIP, but runs things github.com/mesham/tt-sim
