On the other hand, despite my complain about the standard API, the models were able to come up with cooptmat1 kernels that run dsv4 flash faster than whatever the guys at antirez/ds4 can come up with using rocm, on a strix halo, with the added benefit that I can also pair the strix halo with an egpu to drastically speed things up.

From what I can tell, coopmat2 can get to about 75~90% of cuda performance on a single device, and there is no good way to do direct communication across devices. It is fair to say that nobody would replace cuda with coopmat2? That looks like a EEE project that can assigned to a couple of nvidia engineers, to fragment the ecosystem.
