I work for AMD on our GPU math libraries. If you have specific complaints, I will gladly listen. I can't promise more than that, but I will read and consider whatever you write.

I'm a true believer in ROCm HIP. It has tremendous potential. I joined the company specifically because I wanted to help ensure its success... mostly by writing fast, reliable code, but also by listening to our users.

If you (or anyone else) would prefer to respond privately, my email is my HN username at gmail.
