Hi Greg,
I would like to update that yesterday AWS launched new EC2 instances
powered by the Gaudi accelerators. It is now in general availability,
and anyone can launch an instance with those devices.
Therefore, one can now take the upstream driver, hl-thunk, tpc llvm
compiler and SynapseAI core and execute compute kernels on the Gaudi
devices. I have verified this to be working with the driver in kernel
5.15-rc6.

We are still missing the networking parts, but I hope to start
upstreaming them in the next coming months.

Thanks,
Oded
