I've got a #vulkan question for all you smart beautiful vulkaneers out there:
If I got a shader with a local size of (32, 1, 1) aka it has a work group size of 32, the subgroup size happens to be 8 for Reasons, then I have four (4) subgroups per dispatched work group.
I want to use subgroupAdd. Am I on my honor to figure out how to combine the results generated by each subgroup, or does GLSL add some code gen to do that for me?
EDIT: answer is in the replies
Der "Zombie"-Vulkan Uturuncu in den Anden erwacht nicht – aber unter ihm brodelt es gewaltig!
Forscher*innen fanden den größten Magmakörper der Erde & erklären Erdbeben, Gasströme und die mysteriöse "Sombrero-Verformung".

Magma in Bewegung: Wann wird eine Eruption ausgelöst?
Ein internationales Forschungsteam hat mit Beteiligung unserer Uni untersucht, wie lange es dauert, bis ein #Vulkan aufgrund von Prozessen tief im Erdinneren ausbricht. Dazu analysierte das Team Ablagerungen von einem #Vulkanausbruch vor etwa 40.000 Jahren: https://www.uni-goettingen.de/de/3240.html?id=7762

Kilometerhohe Aschewolke nach Vulkanausbruch auf Philippinen
Auf den Philippinen ist der Vulkan Kanlaon ausgebrochen und hat eine mehrere Kilometer hohe Aschewolke in den Himmel gespuckt. Zahlreiche Anwohner wurden evakuiert, Schulen betroffener Dörfer sind geschlossen.
I have #macos, #windows and #linux installations for #vulkan game engine development. On #macos I feel the walls of Apple's garden closing in from all sides. Windows has become a horrible mess. Window management is abysmal, winget, although a step in the right direction, breaks sometimes and don't get me started on ads in the Start menu of the Pro edition...WTF MS?!
The only thing superior in #macos is touchpad gestures and scrolling (sometimes) but I am not sure if this is due to hardware or software.
#Linux using #KDE or #GNOME just gets out of the way and simply works. Window management is great, even on the very opinionated #GNOME desktop with limited customization options. Everything feels swift, battery lifetime on my 5 year old Dell Precision is great and I appreciate having full control of the system without all this cloud account BS.
