1·To understand the reverse mapping technique, let's quickly go through some fundamentals of the Linux virtual memory system.

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。

2·The whole point of a virtual memory system 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。

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

实验结果表明，该方法扩展了可有效解决的核外问题规模，大数据量时的计算性能优于虚存系统。

4·It reports on all layers of file system utilization, including the Logical Volume Manager (LVM), virtual memory, and physical disk layers.

它报告文件系统的所有层的使用率，包括逻辑卷管理器(LVM)、虚拟内存和物理磁盘层。

5·Before executing, the test adjusts its total memory usage according to how much real and virtual memory exist on the system.

在执行之前，测试会根据系统中存在多少物理和虚拟内存来调整其总的内存使用情况。

6·They compare this situation to the time when developers had to seemingly write operating system level code to handle multi-tasking or virtual memory management.

他们将这种情形比作开发者似乎不得不要书写操作系统级别代码来处理“多任务”或“虚拟内存管理”的时代。

7·I discuss how AIX USES virtual memory to address more memory than is physically on your system.

我将介绍AIX如何使用虚拟内存来寻址比系统中物理内存更大的内存。

8·We discuss how AIX 7 USES virtual memory to address more memory than is physically on your system.

我们将介绍AIX 7如何使用虚拟内存来寻址比系统物理内存更大的内存。

9·He's created a way for people to use an older model computer as a virtual desktop, outsourcing its processing power, memory and operating system to another piece of equipment located down the hall.

他已经发明了一种方法，让人们用老式电脑作为“虚拟桌面”，将其处理性能、内存和操作系统外包到某个中心的另一台设备上。

10·If you try to tune a server when there is no free CPU or where the operating system is swapping virtual memory, you won't get very far.

如果您在没有空闲cpu时或者在操作系统需要交换虚拟内存的地方试图优化服务器，则无法使其变得很快。
