英汉例句

• the remainder of this article provides details on how the page replacement daemons target pages for eviction.

  本文剩下的部分将详细地介绍分页替换守护进程如何选择要进行回收的分页。

• you can use system tunable parameters to control the behavior of the aix page replacement daemons and control how aix treats different classes of pages page replacement.

  您可以使用各种系统可调参数来控制aix分页替换守护进程的行为，并控制aix处理不同类型分页的分页替换的方式。

• a page replacement daemon is referred to as lrud (shows up as lrud in the output of ps -k).

  其中一个分页替换守护进程称为lrud（显示为ps-k的输出中的lrud）。

• when the number of non-computational pages (numperm) is less than or equal to minperm, the aix page replacement daemons target both computational and non-computational pages.

  当非计算性分页的数目（numperm）小于或者等于minperm 的时候，aix 分页替换守护进程将选择计算性分页和非计算性分页进行操作。

• further, the guest operating system has the most information about the workload「s memory use and should be able to make the best page replacement decisions.

  更进一步，客户操作系统具有最多的关于工作负载的内存使用的信息，应该能做出最好的页面替换决策。

• the virtual memory pages whose page frames are to be reassigned are selected using the vmm」s page replacement algorithm.

  可以使用vmm的页面置换算法来选择要重新分配页帧的虚拟内存页面。

• vmm is constantly lurking and working in the background trying to steal frames that have not been recently referenced, using the page replacement algorithm i discussed earlier.

  vmm 常驻内存并在后台运行，尝试替换最近没有使用的页帧，其中使用到前面介绍的页面置换算法。

• 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。

• if the page is unmodified, the page replacement daemon can simply mark the physical memory block as free, and the physical memory block can then be re-used for another page.

  如果该分页没有经过修改，那么分页替换守护进程可以简单地将物理内存块标记为空閑，这样一来，就可以将该物理内存块重用于另一个分页。

• the two most basic page replacement tunable parameters are minperm and maxperm.

  minperm和maxperm是两个最基本的分页替换可调参数。

• in this client-only mode, the aix page replacement daemons strictly target client pages.

  在这种仅客户端的模式中，aix分页替换守护进程将严格地选择客户端分页进行操作。

• virtual memory page replacement algorithm is an important component of virtual memory manager.

  页面置换算法是操作系统请求页式存储管理中的一个重要组成部分。

• because the page replacement algorithm is always looking for free frames while it is doing its scanning on systems with a lot of memory, the number of frames to scan can be significant.

  在对有大量内存的系统进行扫描时，因为页面置换算法始终寻找空閑帧，所以需要扫描的页帧数量非常大。

• the page replacement daemons target different types of pages for eviction based on system memory usage and tunable parameters.

  分页替换守护进程可以根据系统内存的使用情况和可调参数，选择不同类型的分页进行回收。

• the database buffer page replacement algorithm has an important impact in the performance of the database system.

  主要介绍在数据采集系统的软件编制中合理的使用内存作为数据缓沖区的方法。

• this is the page replacement algorithm to solve the problem.

  这就是页面替换算法要解决的问题。

• cycle/s—reports back the number of page replacement cycles per second.

  cycle/s——报告每秒的页面置换周期数。

• virtual memory page replacement is an important part of virtual memory management.

  页面置换算法是操作系统中虚拟存储管理的一个重要部分。

• the way it worked in the past was actually quite simple: if your file pages (numperm%) were greater than the actual maxperm%, then the page replacement would only steal file pages.

  以前，它的工作方式非常简单：如果您的文件页面 (numperm%)大于maxperm%，那么页面置换算法将仅替换文件页面。

• vmm is constantly lurking and working in the background trying to steal frames that have not been recently referenced, using the page replacement algorithm discussed earlier.

  vmm一直在后台运行，尝试使用前面介绍的页面置换算法偷取最近没有引用过的页帧。

• in order to help optimize which pages are selected for replacement by the page replacement daemons, aix classifies pages into one of two types

  为了帮助分页替换守护进程更好地选择用来进行替换的分页，aix将分页分为下面两种类型

• when numclient reaches the maxclient limit, the aix kernel starts page replacement in a special, client-only mode.

  当numclient达到maxclient限制时，aix内核将采用特殊的、仅客户端的模式开始分页替换。

• but in some cases, lru algorithm causes many page faults, so improving lru page replacement algorithm can reduce page faults, and therefore improve the performance of the system.

  但lru算法在某些情况下会产生较多的缺页失败，改进lru算法，降低缺页失败次数，可以有效地提高系统性能。

• it is described how the virtual storage is implemented from the auxiliary storage management, main storage management and page management (page fault handling, page replacement role etc. ) .

  首先从辅存管理、主存管理及页面管理（缺页处理、淘汰规则等）三方面说明虚拟存储器是如何实现的。

• if the page is modified, the page replacement daemon writes the page out to a secondary storage location (for example, paging space or file system disk).

  如果该分页经过了修改，那么分页替换守护进程将该分页写入到辅助存储位置（例如，分页空间或者文件系统磁盘）。
