In order to take full advantage of code and device, it incorporates these two kinds of methods. The static code restructuring methods focus on large-size array access in nested loops.
针对磁盘设备的静态代码重构关注嵌套循环中对于大规模数组的访问,在讨论了数据访问模式与快速存储设备数据本地性的关系等问题后,提出了三种循环优化方法:循环融合、循环分拆、循环扩充。

Many operations require you to work through nested loops.
很多时候,你可能需要进行嵌套操作。
Methods with loops, and particularly nested loops, can be time-consuming to execute.
执行带有循环(特别是嵌套循环)的方法可能需要耗费很多时间。
Don't write doubly nested loops just to show off your ability to break or continue an outer loop.
不要写双重嵌套循环只是为了炫耀你打破或者继续一个外循环的能力。
We saw some quadratic algorithms, typically those are things with multiple nested loops, or iterative or recursive calls, where you're doing, say, a linear amount of time but you're doing it a linear number of times and so it becomes quadratic, and you'll see other polynomial kinds of algorithms.
我们看过一些平方算法,他们一般进行了多次嵌套循环,或者递归迭代调用,对一个线性操作调用线性次,这样就变成平方次了,以后你们能看到,一些多项式算法。
