5 Years Late, Only #2 Supercomputer Aurora Misses Targets
[…]
The submission produced 0.585 ExaFLOPs, around a quarter of the expected performance, consuming 24.7MW, around half the power.
It becomes a particularly poignant question when we compare the result to the world #1 supercomputer. This is Frontier, which was delivered 18 months earlier, and delivered 1.2 ExaFLOPs while consuming 22.7MW of power. So roughly double the performance, for the same power, but 18 months ago.

The ratio of RPeak to RMax gives some insights into each system on the Top500 list as to how easy it is to extract performance from a system. Typically a system with a high RPeak to RMax is a crown worth holding.
Most accelerator based systems on the list sit in the 65-75% range, and a select few sit above 80%. Anything lower than 60% sounds unoptimized or may have additional consideration.
The Aurora submission only reaches 55% of that ratio.

Still plenty of work to do, I guess.
