Here is a recent training from AMD for Frontier: Link: https://www.exascaleproject.org/event/amd-gpuprogramming-hip/ https://www.exascaleproject.org/event/amd-gpuprogramming-hip... Video: https://youtu.be/3ZXbRJVvgJs https://youtu.be/3ZXbRJVvgJs Slides: https://www.exascaleproject.org/wp-content/uploads/2017/05/ORNL_HIP_webinar_20190606_final.pdf https://www.exascaleproject.org/wp-content/uploads/2017/05/O... It will be very interesting to see what AMD came up with to convince ORNL to switch from 7 years (or more?) of NVIDIA to something else. I don't think it's just a lower price. Perhaps AMD is doing a closer tie-in between CPU and GPU. Since they own both.

I seem to recall that part of the DoE's selection criteria is to ensure a competitive market for future contracts (since they will always be buying more supercomputers). Given the recent dominance of Nvidia in the market (see https://www.top500.org/lists/2019/06/ https://www.top500.org/lists/2019/06/), it probably made sense for them to ensure some contracts went to other suppliers (AMD for Frontier, Intel for Aurora) to ensure that Nvidia doesn't establish a monopoly on future tech. Additionally, these sorts of supercomputers are also a way for governments to implicitly subsidise their tech industries: when viewed through that lens, spreading these contracts around makes a lot more sense.

Word on the street is that Nvidia insisted that they pay the full price for the GPUs this time and were giving them at a discounted rate prior.
