"Each atomic step would normally take over 5,000 CPU hours on a supercomputer. Now, we can do the same calculation in 2 milliseconds on a desktop,"

Is this phrase equivalent to "Each atomic step would take 5,000 hours on a desktop. Now, it takes 2 CPU milliseconds on a supercomputer."? ^^

This is an interesting result. It makes me wonder if you could grow a silicon ingot in this way. If so it would cut the cost of silicon solar cells significantly (a big chunk of their cost is the cost of the ingot, the ingot cost is a function of time to produce, producing them quickly would get more ingots per unit time from a given reactor).

Another crystal structure that would be useful would be sapphire for things like sapphire screens and other covers.

No, they have developed new software wich works much faster. See a few paragraphs above the one you are quoting.

I read it as: for the same calculation, what would have previously taken 5,000 CPU cores * hours ran on a supercomputer can now be run in 2 milliseconds on a desktop. Or about roughly 10 orders of magnitude faster
