Most of it is German, but there's always some English content in there as well. And it is nice to learn about the new computer Lion Cubs, as well as to see the HPC Days featured: www.cs.cit.tum.de/sccs/weiterf...

Our Correctness & Debugging workshop came to an end on Monday, and we have summarised the outcomes at shareing-dri.github.io/events/20251... We'll certainly run one or two more of these events within the HAI-End project, and use the insights to feed into @shareing.bsky.social
Correctness and Debugging Workshop Series
Within modern, complex software landscapes, developers typically spend a significant proportion of their time on debugging. Studies estimate that more time is required to find bugs than to write actua...

In this paper, we extend our concept to let a compiler offload kernels to the GPU through annotations (so similar to OpenMP pragmas). Previously, it converted data SoA and rewrote the compute kernels automatically to work only on these slimmed down data views.

Compiler-supported reduced precision and AoS-SoA transformations for heterogeneous hardware
This study evaluates AoS-to-SoA transformations over reduced-precision data layouts for a particle simulation code on several GPU platforms: We hypothesize that SoA fits particularly well to SIMT, whi...

Results from SHAREing @shareing.bsky.social are shared (pun intended) by Martyn Guest at #CIUK2025. The project hosted at @durham-comp-sci.bsky.social and @arc-durhamuni.bsky.social is one of two UK Accelerate Computing hubs. All of the results will (one day) be available from shareing-dri.github.io
