A benchmark for hash tables and hash functions in C++, evaluate on different data as comprehensively as possible - renzibei/hashtable-bench
11.2是第11章的主要内容,11章叫散列表(Hash Tables)11.2也叫散列表(Hash Tables) 11.3节讲散列函数(比如除尘散列法),11.4节讲处理碰撞的另外一种方法区别于链式法技术 散列技术,有两个事情要做,一是先哈希函数(11.3),二是解决碰撞技术(11.2链式解决碰撞,11.4开放寻址解决碰撞)。 1 1 2 3 4 5 6 7 8 9...
通过使用并发的 SSE2 指令,这些 hashmap 可以允许一次并发查找 16 个槽位,即使当 hashmap 的填充率已经达到 87.5% ,也可以保持快速。 重要:本仓库借鉴了abseil-cpp仓库的代码, 做了修改,并且可能和原版本行为不同。本仓库是独立工作,像其他开源项目一样不提供保证。请访问abseil-cpp获取官方的 Abseil 库。 安装...
In many situations, this is a fine solution - lookups are reasonably fast, andenvironments are highly flexible, allowing one to store virtually any type of R object (functions, lists, other environments, etc.). However, one of the major downsides to usingenvinronments as hash tables is the...
hash_tables_ :这是一个哈希表vector,每一个元素都是一个hash_table(NvHashTable),本地每一个GPU对应这个vector之中的一个NvHashTable。目的是为了把高维矩阵的row offset 转换为低维矩阵的 row offset。 在hash_table 内部,逻辑上来看每一个元素可以认为是 <key, value_index>(其实内部是个黑盒子,只是对外逻...
Consistent hashing is a special kind of hashing such that when a hash table is resized, only K/n keys need to be remapped on average, where K is the number of keys, and n is the number of slots. In contrast, in most traditional hash tables, a change in the number of array slots...
* supported for the benefit of hash tables such as those provided by * {@link java.util.HashMap}. * ... * As much as is reasonably practical, the hashCode method defined by * class {@code Object} does return distinct integers for distinct ...
tables in the ST monad, as well as a typeclass abstracting their common operations, and a set of wrappers to use the hash tables in the IO monad. . /QUICK START/: documentation for the hash table operations is provided in the ...
the value 9 comes fromsizeof(void *) + 1, as thenodehash maps store one pointer plus one byte of metadata for each entry in the bucket array. flat tables store the values, plus one byte of metadata per value), directly into the bucket array, hence thesizeof(C::value_type) + 1....
