鉴于自己的毕设需要使用GPU CUDA这项技术,想找一本入门的教材,选择了Jason Sanders等所著的书<CUDA By Example an Introduction to General Purpose GPU Programming>.这本书作为入门教材,写的很不错.自己觉得从理解与记忆的角度的出发,书中很多内容都可以被省略掉,于是就有了这篇博文.此博文记录与总结此书的笔记和理解.注意本文并没有按照书中章节的顺序来写.书中第8章图像互操作性和第11章多GPU系统上的CUDA C,这…

Hash function From Wikipedia, the free encyclopedia   A hash function that maps names to integers from 0 to 15. There is a collision between keys "John Smith" and "Sandra Dee". A hash function is any function that maps data of arbitrar…

In data structure Hash, hash function is used to convert a string(or any other type) into an integer smaller than hash size and bigger or equal to zero. The objective of designing a hash function is to "hash" the key as unreasonable as possible.…

技术在于交流.沟通,本文为博主原创文章转载请注明出处并保持作品的完整性 在前面我介绍过hash的使用,本次主要介绍一下Hash Function Hash Function即获得hash code的函数,根据其获得的hash code放到指定的bucket中,那么为了保证其hash的效率我们应尽量避免碰撞,所以hash Function所产生的hash code应足够的乱 下面介绍一个万用的hash function及其测试代码 首先我们创建一个客户类,它有三个成员变量 姓,名,年龄 class…

http://blog.csdn.net/kingstar158/article/details/8028635 由于工作需要,针对千万级别的数据,使用stl::map着实存在着效率问题,最后使用boost::unordered_map替代前者,发现效率上有很大的提升,但是还是无法达到我们的需求: stl::map  底层算法:B+tree 实现 boost::unordered_map 底层算法:hash 实现 所以可能要针对不同的数据类型编写hash function来优化查找和插入的效率,…
