Nested loops with index locality P&L: -3 ħ (≃ -246 CNY)

Can we loop and avoid cache misses for computer performance?

If you iterate over data, the most efficient retrieval is where the data is all in a line.

How do we arrange data so that data is always near the previous data we retrieved?

-3.0000 ħ (3.0 HUR) (+0.0) I wrote a nested for loop that iterates in reverse order between iterations to minimize cache misses.

我在这上面花了几个小时。

如果这适用于所有程序循环，我们可以拥有更高效的程序。

I spent a few hours on this.

If this was applied to all looping of programs, we could have even more efficient programs.
