I already read it, but still don’t understand.
It says the wavefront is
Number of unique “work packages” generated at the end of the processing stage for requests. All work items of a wavefront are processed in parallel, while work items of different wavefronts are serialized and processed on different cycles.
What are ‘work packages’, ‘processing stage’, and ‘items’? What about ‘at the end’ of the processing stage? Is ‘work package’ the number of sector accesses per request? I searched the term in the very same document but I could not find answers. This abstraction is confusing, so I would be grad if those are elaborated more.
