Bitonic order implementation code with mpi usage

一个用c写的机遇MPI的并行程序，程序实现了求积分的功能(with a c MPI the opportunity to write parallel programs, procedures for the realization of the functional integration)

详细的kmp并行算法实现源代码，在机群系统上适用，并附加详细的算法说明(Kmp parallel algorithm in detail the source code for the cluster systems, and additional details of the algorithm description)

采用cuda对dijkstra算法进行并行实现，性能提升7倍多。( U91C7 u75286 u5B09 u5B09 u7)

说明：  主要是自己学习时做的习题，希望对你有帮助(Mainly to their own learning exercises to do, want to help you)

一个基础的CUDA例子，绘画出julia集合。(One based on CUDA example, draw julia set.)

设计MPI程序模拟广播（MPI_Bcast）操作：将每个MPI进程按照所在节点名称建立node通信子域分组；再将各个node子通信域的0号进程再次组成一个名为head的通信域；在进行广播时，首先，由root进程将消息在head通信子域内广播，然后，再由head子域内各进程在其所在的node子域内进行广播。(Design the MPI program MPI_Bcast operation: Each MPI process establishes a node communication sub-domain grouping according to the node name; then, each process of the 0 node of each node sub-communication domain is again formed into a communication domain named head; At first, the root process broadcasts the message in the head communication sub-domain, and then the processes in the head sub-domain broadcast in the node sub-domain where it is)

mpi的源码，示例程序等，主要用于对mpi并行编程程序的研究。(mpi source code, sample programs, mainly for mpi parallel programming procedures.)

基于C语言的，在共享内存的并行机上使用OpenMP并行环境实现矩阵乘法(C-based, shared memory parallelism using OpenMP on a parallel machine environment to achieve the matrix multiplication)

说明：  本文介绍的基于多线程和图像分块实现加速运算，因为调用了opencv库，比较容易编写和实现。OpenCV全称是是Open Source Computer Vision Library，它是由Intel微处理器研究实验室的视觉交互组开发，是一种用于数字图像处理和计算机视觉的开源函数库，采用的开发语言是C++。(This paper introduces an acceleration algorithm based on multi-threading and image partitioning, because it is easy to write and implement by calling the opencv library. OpenCV is called Open Source Computer Vision Library. It is developed by the Visual Interaction Group of Intel Microprocessor Research Laboratory. It is an open source library for digital image processing and computer vision. The development language used is C++)
