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

Well done to my @epcc.bsky.social PhD student Gabriel Rodriguez-Canal who presented his paper at the #LLVM #SC25 workshop today on an MLIR-based Fortran & OpenMP flow for #AMD #FPGAs. Preprint at arxiv.org/pdf/2511.08713

A wide range of talks so far this morning at the @riscv.org.web.brid.gy #SC25 workshop. Driving analogue systems from #RISCV, coupling with spiking neural networks, and profiling tooling all demonstrates the flexibility the technology gives us to do cool things

Shashank Nemawarkar from #condorcomputing, part of #andes , kicks off the @riscv.org.web.brid.gy workshop at #SC25 talking about #hpc CPU design. Lots of interesting talks ahead this morning.

Steve Dean from HPE kicking off the “Sustainable Supercomputing” workshop at #SC25 - the room is pretty packed already, but there are a few more seats in room 264 if you want to join. Lots of interesting presentations still to come!

Was great to visit @ncar-cisl.bsky.social last week in Boulder and Cheyenne, we have a centre to centre collaboration via the #EPSRC #CONTINENTS project and they have some really impressive facilities and work. Great discussions ahead of then travelling to St. Louis for #SC25 this week

The @epcc.bsky.social #SC25 booth starting to go up, hanging sign and all

Thanks @riscv.org.web.brid.gy publishing my article highlighting #RISCV activities coming up at #SC25 this week, a workshop on Monday morning showcasing some of the latest developments and then a panel on adopting a fully open #HPC ecosystem on Thursday 1:30pm riscv.org/blog/risc-v-...

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

Was great fun teaching the @tenstorrent.bsky.social tutorial at @ieeexplore.bsky.social #CLUSTER with @fclc.bsky.social this week. And thanks Owain Kenway for finding (and fixing!) the bugs in the practical exercises ;) Great to introduce the architecture to new people!

@riscv.org.web.brid.gy for #HPC workshop at #SC25 will be held on Monday 17th November in St Louis. The paper deadline has been extended until 15th of August, accepting both full papers and work in progress. edin.ac/3Uyeclp

Great to see our knowledge exchange project (cake-dri.github.io) being represented properly at meetings. Thanks to Eleanor Broadway @epcc.bsky.social

I've really enjoyed #PASC25 this week in Brugg, where there have been many insightful talks. The highlight for me was our mini-symposium on moving to more sustainable #HPC (as part of #CONTINENTS) and I spoke to Maria from @cscsch.bsky.social about the session youtu.be/-PGgfDSEWUs?...

@paulbcfd.bsky.social , #CFD expert @epcc.bsky.social presents ASiMoV-CCS at #PASC25 which is a new #CFD solver providing improved opportunities for running at scale. A great example of using modern #Fortran
