I don't understand. If they document their stuff with errors, it will hurt users, be they chinese or US ? Or is it expected that US users will call Nvidia's to ask for the correct documentation ?
It could be a case of classic market segmentation. The lower tier customers get the incomplete or error-ridden documentation, and the upper tier trusted customers^W'partners' get access to the juicy stuff: complete and mostly correct documentation, including stuff intentionally left out of the lower tier package like application notes containing secret hardware handshakes to unlock hidden features, all under strict NDA of course.
The vast majority of users use NVidia’s own kernels versus optimize their own. And those who do write custom kernels are typically not trying to compete with NVidia’s own GMM.
