I've been super curious to see what was at stake here! This sounds better than I'd dared to hope for.
I kind of thought this was just gonna be some kind of deferred texture loading thing, help with streaming assets.
If it actually allows inter-warp sequencing, it sounds like it might possibly solve the chief complains supreme GUI master Raph Levien recently had in I want a good parallel computer, which so that even though we can dynamically add shaders & construct a dynamic workgraph (largely thanks to VK_AMDX_shader_enqueue?), there isn't any sequencing/fencing/barrier-ing between the sections. https://raphlinus.github.io/gpu/2025/03/21/good-parallel-computer.html https://raphlinus.github.io/gpu/2025/03/21/good-parallel-com...

Not applicable to GPUs, but since I ran into it recently, it's interesting to see how io_uring handles sequenced submissions. Here's Lord of io_uring's write-up, https://unixism.net/loti/tutorial/link_liburing.html#link-liburing https://unixism.net/loti/tutorial/link_liburing.html#link-li...
Edit: having read the article more fully, I'm not sure this is about waves depending on each other. Maybe more about them trying to access memory. Apologies. Hopefully someday!
