1. What is aspect-oriented programming?(什么是面向切面编程?) Aspects help to modularize cross-cutting concerns.(切面帮助我们模块化横切关注点)In short, a cross-cutting concern can be described as any functionality that affects multiple points of an application.(简单来说, 一个横切关注…

自己做的部分习题解答,因为时间关系,有些马虎,也不全面,欢迎探讨或指出错误 5.1 Consider the matrixaddition in Exercise 3.1. Can one use shared memory to reduce theglobal memory bandwidth consumption? Hint: analyze the elementsaccessed by each thread and see if there is any commonality b…

62. Unique Paths 方法一: 二位数组 而这道题是每次可以向下走或者向右走,求到达最右下角的所有不同走法的个数.那么跟爬梯子问题一样,需要用动态规划 Dynamic Programming 来解,可以维护一个二维数组 dp,其中 dp[i][j] 表示到当前位置不同的走法的个数,然后可以得到状态转移方程为:  dp[i][j] = dp[i - 1][j] + dp[i][j - 1] class Solution { public int uniquePaths(int m, i…

近几年,业内对并行和并发积累了丰富的经验.有了较深刻的理解.但之前积累的大量教材,在当今的软硬件体系下.反而都成了负面教材.所以,有必要加强宣传,翻新大家的认知. 首先.天地倒悬,结论先行:当你须要并行时,优先考虑不须要线程间共享数据的设计,其次考虑共享Immutable的数据.最糟情况是共享Mutable数据.这个最糟选择.意味着最差的性能,最复杂啰嗦的代码逻辑,最easy出现难于重现的bug,以及不能測试预防的死锁可能性.在代码实现上.优先考虑高抽象级别的并行库(如C++11的future.…
