My @durham-comp-sci.bsky.social PhD student Pawel Radtke just won the best poster award at #SIAMPP26 on our compiler work.

It kind of strikes me that SIAM CSE has always multiple sessions on training and teaching. #SIAMPP26 has none. Thats a missing piece in the puzzle and where @shareing.bsky.social has to step in. Computational Sciences training is important. So is HPC from a methodological/algorithmic point of view.

Great poster session at #SIAMPP26. @shareing.bsky.social was there and our eCSE project (a collab between @durham-comp-sci.bsky.social and @epcc.bsky.social ) as well as two further posters around Peano and the continuation of our PAX-HPC ExCALIBUR work.

Meeting with other TOMS (associate) editors at #SIAMPP26. It is always good to meet the people behind a journal portal.

2hrs in at #SIAMPP26 and a first talk using ExaHyPE. The observations re precision are interesting. Punchline: low precision pollutes a lot of the outcomes and one has to be very very careful using it.

Did you know that @durhamphysics.bsky.social researchers are involved in the search for life on distant planets? They're investigating how a UK-led team could design and build a core instrument for the new NASA Habitable Worlds mission due to launch in the 2040s πŸ‘‰ tinyurl.com/3fmwfyur
