39th POP Webinar – ParaViz3D: MPI Trace Visualization with 3D Video
On the 23rd of February Jean-Yves Verhaeghe (FAU) gave an inspired webinar on ParaViz3D, a framework that converts MPI trace data into 3D video visualizations using Blender, making complex parallel program behaviour easier to interpret than traditional 2D trace views.

40th POP Webinar – Analysis and Optimization at Production Scale: Insights from Vlasiator
In the 40th POP Webinar on the 30th of March Valentin Seitz (BSC) showed how POP performance-analysis tools can be applied to study the behaviour of the Vlasiator plasma simulation code at full production scale, providing insights that go beyond traditional small-scale profiling.
