It was great to visit OpenChip last week in Barcelona, presenting on the latest developments in #RISCV for #HPC, inc some takeaways from #ISC, and discussing research opportunities to help inform next-generation computing

Thanks #HPCwire for the write up of our #risc_v #BoF session at #ISC26. One reason I organise this each year is that getting feedback/criticism from the #HPC community keeps us honest and ensures we aren't preaching to the already converted. www.hpcwire.com/2026/07/20/c...

Charting RISC-V’s Future in HPC - HPCwire

There are more than 30 billion RISC-V cores deployed in the world, and some analysts estimate the open processor architecture will own a third of the market within five years. While the forecasted fut...

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...

Maintainer Spotlight: xDSL

An accessible, high-productivity compiler framework for experienced and new compiler developers, compatible with MLIR and used in academia and industry for teaching, research, and production compiler ...

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@epcc.bsky.social · 3mo ago

Fully-funded EPCC PhD: investigate the potential of novel accelerators. Run in collaboration with AWE, who will provide real world mini-applications and algorithms of genuine scientific interest. Applicants must be UK nationals. Apply by 28 May 2026. Read more at: edin.ac/4979QJO

@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

EPCC is hiring! We have the following vacancies: Collaboration Manager edin.ac/4oZHnuw Applications Developers edin.ac/491r4HA Closing date for both posts is 14 January 2026.

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 ;)
