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.

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

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

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!

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

Jake Davies, one of my PhD students @epcc.bsky.social presents our work on accererating #FFT on @tenstorrent.bsky.social #wormhole at @riscv.org.web.brid.gy for #HPC . #wormhole is around three times more energy efficient than a 24-core Xeon Platinum and I think we can push this even further
