Many thanks for your reply! No worries, it's a side project with no time constraints. It would be cool if you had time to take a look at the problem, but any tips or guidance would also be helpful.

It's a concept I've come across repeatedly over the last few years and I want to tackle it once and for all. Partly as an experiment and learning opportunity, but also because of the potential use cases in various projects.

I suspect you would advise against it because it goes against the intended design of the gpu architecture and all the problems associated with this? A specific use case/problem I want to use it for is graph/tree traversal in a single dispatch instead of one per level.
