"especially when you need to make sure that 30+ year-old code still work like it's the case in HPC"

Most code that works on Intel works on AMD. It's rare that it doesn't. The HPC vendor will have low risk on migration + get a bunch of competing accelerators at various price points for their problem. This is quite an incentive to move even if there would be stragglers.

I have no doubt they do, but still...

The question is : are the DOD/DOE (or the chinese/european equivalent) going to risk millions for their next supercomputers on a new architecture or prefer good old intel ?

Especially when we know that the jump to exascale computation will only be possible if we get rid of the buses and have everything on the same chip (which is one direction taken by Intel).

My point is that the conclusion of the article "Intel has to come up with an answer..." is just plain wrong. This new architecture is an answer to intel new developments. We will have to wait to see what stick to the wall.

They're the people that bought all the POWER's (SP2 onward), Alphas, Itaniums (eg SGI), Cell's, and so on. They'll take risks esp if they think the firm will be around to supply the upgrades.

IBM is already building two new supercomputers for DoE based on Power. (Look up the CORAL Project.)
