locality of reference 中文意思是什麼
locality of reference
解釋
訪問局部性-
Reference counting is simple, lends itself well to incremental collection, and the collection process tends to have good locality of reference, but it is rarely used in production garbage collectors for a number of reasons, such as its inability to reclaim unreachable cyclic structures objects that reference each other directly or indirectly, like a circularly linked list or a tree that contains back - pointers to the parent node
引用計數很簡單，很適用於增量收集，收集過程一般會得到好的引用區域性，但是出於幾個理由，它很少在生產垃圾收集器中使用，如它不能回收不可到達的循環結構（彼此直接或者間接引用的幾個對象，如循環鏈接的列表或者包含指向父節點的反向指針的樹） 。 -
Why is the rateable value not linked directly to the actual rent ? in assessing the rateable value, the rvd has to take into account open - market rents agreed at or around the valuation reference date for similar properties in the locality, with due adjustments to reflect any differences in size, location, facilities, standards of finish and management
估價署在評估應課差餉租值時，須要考慮區內同類物業于估價日期（即10月1日）或接近該日，在公開市場由業主與租客雙方議定的租金，再根據物業的面積、位置、設施、完工質素及管理水平的差異加以調算。 -

In some cases, however, using the default heap can reduce locality of reference
然而，某些情況下，使用默認堆可以減少引用地址。 -
Smaller working sets mean better locality of reference, fewer page faults, and more cache hits
較小的工作集意味著更好的引用地址、更少的頁錯誤和更多的緩存命中。 -
The process working set is the closest metric the operating system directly provides for measuring locality of reference
進程工作集是操作系統為測量引用地址直接提供的最接近的尺度。 -
Because the cost of a page fault is high, it is desirable that a garbage collector properly manage locality of reference
因為頁面錯誤的成本很高，所以垃圾收集器正確管理引用的區域性（ locality ）是很必要的。 -
This function can generate many calls and access a lot of memory in different data areas, leading to bad locality of reference
該函數可以在不同的數據區域中生成許多調用和訪問許多內存，從而導致極差的引用地址。 -
Sometimes a data structure that looks great turns out to be horrible because of poor locality of reference, and sometimes the reverse is true
有時看上去很棒的數據結構由於引用地址不好而變得很糟，有時正好相反。 -
To avoid this, it s important to use data structures with good locality of reference, which means keeping related things together
為避免此問題，使用具有良好引用地址的數據結構很重要，這意味著將相關的事物合在一起。 -
While some believe that the job of the garbage collector is simply to reclaim unreachable memory, others believe that the garbage collector should also attempt to improve the reference locality of the user program
雖然一些人認為垃圾收集器的工作只是收回不可到達的內存，但是其他人認為垃圾收集器還應該盡量改進用戶程序的引用區域性。 -
The file system this thesis bring utilizes some characteristics of web proxy, such as the fact that cached web pages do not change in size once cached and access permission do not change, and the reference locality
本文提出的文件系統利用了webproxy負載的一些特點，例如webpages一旦緩存大小就不會發生變化，存取權限也不會發生變化， webpages訪問的鄰接性等。 -
This not only improves locality of reference of the user program and eliminates heap fragmentation, but also greatly reduces the cost of object allocation - object allocation becomes a simple pointer addition on the top - of - heap pointer
這不僅改進了用戶程序的引用區域性並消除了堆碎片，而且極大地減少了對象分配的成本對象分配變成了在堆頂部的指針上增加指針。
