To understand the reverse mapping technique, let's quickly go through some fundamentals of the Linux virtualmemorysystem.
为了理解反向映射技术,让我们来首先简单了解Linux虚拟内存系统的一些基本原理。

The whole point of a virtualmemorysystem is that you can have a virtual address space that's much bigger than the amount of physical memory on the computer.
一个虚拟内存系统的全部重点就是:你可以拥有一个虚拟的地址空间,它比计算机上的物理内存总量还要大。

Experimental results show that this method extends the problem sizes that can be efficiently solved and its performance is better than the virtualmemorysystem while the data set is large.
