| 1. | Thus , the most reliable of the paging paths is that for the paging file 因此,最可靠的页面调度路径就是通过页面调度文件。 |
| 2. | Any access to the paging file must not generate any additional page faults 任何对页面调度文件的访问一定不要产生任何附加的页面错误。 |
| 3. | In a virtual storage system , a condition in which the system can do little useful work because of excessive paging 在虚拟存储系统中,由于过量的页面调度,系统处于难以做有效工作的状态。 |
| 4. | Paging i / o . these are i / o operations initiated by the virtual memory system in order to satisfy the needs of the demand paging system 这类是为了满足“请求页面调度系统”的需求而由虚拟内存系统发起的i / o操作。 |
| 5. | This paging activity will cause the execution of the application to stutter and will distort the runtime of our test program 这种页面调度( paging )活动会使应用程序的执行变得断断续续,并干扰我们的测试程序的运行时。 |
| 6. | Once the working set exceeds available ram , performance usually declines sharply as the operating system starts paging memory out to disk 一旦处理空间超过了可用的ram ,操作系统将页面调度到磁盘,性能通常会急剧下降。 |
| 7. | Paging activity occurs at apc _ level and thus limits arbitrary re - entrancy in order to prevent calling code paths that could generate yet more page faults 页面调度活动出现在apc _ level ,因此为了保护也可能产生更多的页面错误的调用代码路径,它限制了任意重入。 |
| 8. | Sure , memory s cheap these days , but with several java applications running on a machine , even a big machine can be slowed down by constant memory paging 当然,现在内存是便宜,但是当有几个java应用程序同时在一台机器上运行时,即使是大机器也可能由于持续的内存页面调度而放慢速度。 |
| 9. | Further , to avoid serialization problems , the file system is not responsible for serializing this access - the paging file belongs to the vm system , and the vm system is responsible for serializing access to this file ( this eliminates some of the re - entrant locking problems that occur with general file access ) 进一步,为了避免串行化问题,文件系统不负责将访问串行化页面调度文件属于虚拟内存系统,而虚拟内存系统负责把对这个文件的访问串行化(这消除了出现在常规文件访问中的重入锁定问题) 。 |
| 10. | To improve virtual memory management mechanism , the kernel code is amended to avoid the incertitude cause by page scheduling , thus the responding speed is effectively improved . the irrationality of linux scheduling mechanism is also analyzed , and the methods and models such as to fortify scheduling occasion and adopt double kernel are also proposed to improve it 在虚拟内存管理机制的改进上,作者从操作系统内核入手,对内核代码进行修改,去除了由于页面调度带来的响应不确定性,有效的提高了系统的响应速度;在实时调度上,分析了linux现有调度机制的不合理性,提出了增加调度时机、采用双内核等方法,给出了改进的模型。 |
