"This is internal hardware for us, so there's not a lot we can share, and you can't really grab a version of the hardware. If that's a problem for the community, I completely understand.

Mostly, I wanted to offer to upstream this because it seems likely about the same utility as the AMDGPU backend for folks without an AMDGPU, or the XCore backend, etc. It's small, and we're happy maintaining it and taking on any of the effort around it."

Appears to be a network card.

Interesting theory. What do you case this on? The lack of FPU?

A guess, but myricom makes cards based on a chip explicitly called lanai: https://www.myricom.com/hardware/myri-10g-network-adapters/2...

"LANai"

Then again, someone mentioned this very card, and the response was that it was internal hardware, so still a mystery.
