Note: In Windows, the number of threads a process can create is limited by the available virtual memory. 注意:在Windows中,受可用虚拟内存的限制,一个进程可以创建的线程数目是有限的。
All UNIX systems provide tools such as ps and vmstat to provide process and virtual memory statistics. 所有UNIX系统都提供了ps和vmstat之类的工具,通过它们提供进程和虚拟内存统计信息。
Optimization is very important in the process of building a virtual reality scene, especially the optimization in the use of computer memory of display. 在构建虚拟现实场景的过程中,优化是很重要的,尤其是显存方面的优化。
When a process allocates memory it does so by first reserving virtual memory and then committing memory out of this chunk ( this is the memory actually used). 一个进程分配内存时,它是这样进行的:首先,预定虚拟内存;然后,提交内存到该块中(这是实际使用的内存)。
Traditional DSM systems have just implemented a shared memory model upon a physical distributed memory, they don't pay enough attention on how to construct process virtual address space upon these shared memory models. 开发分布共享存储系统的目的是为了在分布式存储器的基础上构造逻辑上的共享存储器模型,对于如何在共享存储器模型的基础上为用户进程构造虚拟空间,传统的分布共享系统并未给予足够的重视。
Based on the Linux kernel source codes, the interrupt, process scheduling, virtual memory, file system and so on are analyzed. 本文以Linux内核源代码为基础,分析了中断处理机制、进程调度策略、虚拟内存、文件系统等Linux的内核机制;
In the traditional operating system, there are two data memory models, one is the process virtual address space that is constructed at the level of main memory, and the other is the file that is constructed at the level of exterior storage device. 传统操作系统分别在内存和外存这两个层次上为用户构造了两种数据存储模型:进程逻辑空间和文件。
The functional requirements of a secure OS are mapped into a secure MMS in accordance with Trusted Computer System Evaluation Criteria. Process isolation, prevention of memory information leak, memory access control and virtual memory protection as four function requirements of secure MMS are first presented. 依据可信计算机系统评估标准,将安全OS的功能需求依次映射到内存管理子系统,初步提出安全内存管理子系统的四个功能:进程隔离、防止内存信息泄露、内存访问控制,虚拟内存保护;
