I agree. That means a LOT of codes will have to be ported from CUDA to
whatever AMD uses. I know AMD announced their HIP interface to convert
CUDA code into something that will run on AMD processors, but I don't
know how well that works in theory. Frankly, I haven't heard anything
about it since it was announced at SC a few years ago.
I would not be surprised if AMD pursued this bid quite agressively,
possibly at a significant loss, for the opportunity to prove their GPUs
can compete with NVIDIA and demonstrate that codes can be successfully
converted from CUDA to something AMD GPUs can use to demonstrate GPU
users don't need to be locked in to a single vendor. If so, this could
be a costly gamble for the DOE and AMD, but if it pays off, I imagine it
could change AMD's fortunes in HPC.

"ease of porting from existing machine"
" CORAL-2 has a mandate to field architecturally diverse machines in a way that
manages risk during a period of rapid technological evolution. “Regardless of
which system or systems are being discussed, the systems residing at or planned
to reside at ORNL and ANL must be diverse from one another,” notes the CORAL-2
RFP cover letter [PDF]."
