I'm cc-ing your message to the Amber developer's group. I think(?)
people have managed to get all of Amber working on a power9/GPU system
called "Summit" at Oak Ridge, but I don't know anything about the status
of that. I don't recall any patches being posted to our development
platform on this subject. Ruzhu Chen has an account at, but I don't think has made merge requests.

I could be mis-remembering here. Developers: anyone have info to share
about power9?

I'm just an intermediary here, and have no real answers to share.
