The Linux kernel operates in a virtual memory mode: for every virtual page there is a corresponding physical page of memory in the system.
Linux内核工作于虚拟内存模式:每一个虚拟页对应一个相应的系统内存的物理页。
The main purpose for large page usage is to improve system performance for high-performance computing applications or any memory-access-intensive application that uses large amounts of virtual memory.
使用大页面的主要目的是,提高高性能计算应用程序或使用大量虚拟内存的任何内存访问密集型应用程序的系统性能。
Each operating-system process is allocated its own virtual address space — a set of virtual-memory pages that it can read from and write to. Each page can be in one of three states.
每个操作系统进程占用自己的虚拟地址空间,即一组可以读写的虚拟内存页。
Improving virtual memory page replacement can reduce page fault rate, and therefore improve the performance of the system.
改进页面置换算法,可以降低页面失败率,从而有效地提高系统性能。
These virtual addresses are mapped to physical memory by page tables, which are maintained by the operating system kernel and consulted by the processor.
这些虚拟地址映射到物理内存页表,这是维护操作系统的内核和处理器咨询。
