I don't understand how this theory about Alpha and Sunway originated. Even if numerology suggested the Sunway chips were Alpha-derived, Dongarra[1] refutes it.

I don't understand how this theory about Alpha and Sunway originated. Even if numerology suggested the Sunway chips were Alpha-derived, Dongarra[1] refutes it. TaihuLight is memory-constrained. The Alphas we used had enough cache to hold a crystallography image, and more-or-less a whole dataset in main memory. If people hadn't insisted on using PDP-11 software designs, visitors would have been even more impressed how fast they were.

- gnufx 6y agoHow does he know? Was Dongarra completely misled, and how come it appears nothing like the Alphas I used, which certainly didn't just have a small scratchpad? Dongarra must have been pretty familiar with Alphas, of course.
