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

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

We’re Showcasing RISC-V at SC25, the World’s Largest Supercomputing Conference
I’m heading to SC25 in St. Louis next week to advocate for the growing role of RISC-V in high-performance computing (HPC), alongside my peers in the RISC-V HPC special interest group (SIG).

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

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!
