On the 12 December 2022 the default CPU frequency on ARCHER2 compute nodes was set to be 2.0 GHz. Previously, the CPU frequency was unset which meant that the base frequency of the CPU, 2.25 GHz, was almost always used by jobs running on the compute nodes. In this post,...

In the evening of March 19th 2021 a volcanic eruption started in Fagradalsfjall, Iceland. Although the episode posed no threat to aviation (no ash was produced), significant amounts of volcanic gases were (and still are being) released. Such gases can cause respiratory problems, and if the concentrations are high enough,...
