In modern mathematics, physics, and computer science; optimized and fasterapp developmentin programming is very important to speed up computations. CPUs and GPUs are highly evolved by the number of cores and transistors to give more computational power to today’s servers and computers. Thus, we ...

Stochastic dynamic programming (SDP) is widely adopted in a long-term optimal operation of large-scale hydropower systems. In this paper we propose a distributed parallel stochastic dynamic programming algorithm based on Message Passing Interface (MPI) and a peer-to-peer parallel paradigm (DPSDPoM)...

}/*gcc -Wall -o fork fork.c -lpthread ./fork*/ 分析一下可能产生死锁的原因 以下是说明死锁的理由: 1. 子进程只拷贝了调用fork的主线程(进程)的2. 在内存区域里,静态变量mutex的内存会被拷贝到子进程里。而且,父进程里即使存在多个线程,但它们也不会被继承到子进程里3. 父进程产生的线程里的doit()...
16.2.3 Spring Framework’s consistent programming model Spring resolves the disadvantages of global and local transactions. It enables application developers to use a consistent programming model in any environment. You write your code once, and it can benefit from different transaction management strateg...
In some cases, the example encoder and example decoder process video frames organized as shown in FIGS. 1,2A,2B and2C. For progressive video, lines of a video frame contain samples starting from one time instant and continuing through successive lines to the bottom of the frame. An interlace...
FIG. 1 illustrates the life of an instruction "A" in a 3-stage pipeline. To gain a performance advantage from pipelining, multiple instructions are executed simultaneously in different stages of the pipeline. FIG. 2 shows the execution of instructions A, B, and C in the pipeline of FIG. ...
