The codesign effort pushed by the new requirements/constraints (power and

The report, as a holistic view of the challenge, suffers from lack of detail
although references are provided for some of their statements. It is obvious
that such effort will require multi year investment in a wide range of
disciplines. It seems a reasonable amount based on the investments within the
HW industry that will seek ROI.
I personally think this cannot be anymore a country-only solely lead effort
and in terms of budget to develop such program, China could be already better
set. Keeping Intellectual Property is going to be difficult under the pressure
to deliver within timelines.
China clearly has the budget and motivation for this sort of work, but
the software skills in China are still considerably behind the rest of
the HPC superpowers. This is something China readily admits, and is
working to address.* At the pace their, moving though, I imagine it
won't be long before this is fixed, but a cultural change like that
would still probably take some time, I'd say 10 or more years.

University gave a few years ago titled "Perspectives on China’s Role in
Global High Performance Computing" (see description at
