thread creationThis book offers an introduction to concurrent, real-time and distributed programming, using Java object-oriented language support as an algorithm description tool. Complete with useful examples and practical exercises, the book is particularly interested in communication using TCP sockets ...

Thread are peers.Any thread in a process can use pthread_join() to join with any other thread in the process.就是说,线程之间相互join与相互的创建关系无关。进程之间只能是父进程对子进程调用waitpid(). There is no way of saying “join with any thread” (for processes, we can do this using...

void thread2() { Y.store( 1 ); r2 = X.load(); } 因为C++11 原子类型保证顺序一致性,结果 r1 = r2 = 0 是不可能的。为了实现这一点,编译器会在幕后输出额外的指令——通常是内存栅栏和/或 RMW 操作。与程序员直接处理内存排序的指令相比,这些附加指令可能会降低实现的效率。

on the GPU. State is a backend specific object to implement functionality like getting the thread index. A GPUArray needs to get passed as the second argument to dispatch to the correct backend and supply the defaults for the launch parameters. ...
1.7 Early History of Reinforcement Learning 没仔细看,大概就是三个thread共同引向了对RL的研究:Bellman写了Bellman equation,是dynamic programming,还搞了Markov decision process;第二个是对trial-and-error learning的研究;第三个即Sutton的temporal difference learning,相较于前两者是小且新且针对于RL问题。
Udacity cs344-Introduction to Parallel Programming笔记(超详细,CUDA,并行,GPU)---Unit 4 1.啥是紧密(compact):这里的压缩指的是过滤,filter,过滤出一个子集,也就是只留我们想要的(比如一把扑克牌里的方片) (只计算我们关心的对象才更有意义,计算代价较小,需要更少空间) 2. 3.密集运算好一点?为啥 第一...
