Head of Research Software Engineering (#RSE, #RSEng) at the University of Cambridge. I am also Co-director of the Institute of Computing for Climate Research Science and a bye-fellow of Queens’ College. I have been doing #HPC since last millenium!

In any case, I'm looking to help researchers use high performance computing HPC resources effectively.

Speaking here on behalf of myself only.

If you are interested in any aspect of #ResearchSoftware, including #RSEng, #funding, #publishing, #training, #metascience, #policy, etc., please consider submitting a proposal to and/or attending #IRSC26 (immediately before #RSECon26 in Sheffield, UK, in Sept). We're trying to bring all elements of the #ResearchSoftware community together

I hope everyone else is enjoying Europeans-are-late-to-meetings-with-US weeks!
We've been working on migrating TESSERA embeddings to a cloud native format called Zarr v3, which unlocks all kinds of scifi usecases like mobile phone use and satellite streaming. A note on how this works: https://anil.recoil.org/notes/tessera-zarr-v3-layout and a preview of browser streaming on https://tze.geotessera.org
Streaming millions of TESSERA tiles over HTTP with Zarr v3

How we restructured TESSERA's geospatial embeddings from millions of individual numpy files into sharded Zarr v3 stores for efficient HTTP streaming, enabling everything from single-pixel mobile lookups to regional-scale analysis with just a couple of range requests.

When you see the news
about all the energies
being devoted
to turning the world
into a wasteland,
it is vital to remember
that applied differently
those same energies
could turn the world
into a garden.

Th RCS team will be at the Cross-Community AMD GPU Hackathon (11–13 March, Birmingham), helping researchers port and optimise scientific codes for AMD GPUs alongside DiRAC and AMD.

Looking forward to supporting some great research software

Happy birthday, PDP-10!
Great advocacy from @openuk for promotion of #opensource within the UK. Procurement practices including open source maintenance promise strong wins. I need convincing on how useful a national foundation would be for a borderless phenomenon? https://openuk.uk/wp-content/uploads/2026/03/Making-the-UK-the-Home-of-Open-Source.pdf
