并行阵列搜索MPI程序，在整数处理。一个元搜索

基于MPI的并行快速排序算法，可以通过并行快速排序提高排序速度-MPI-based parallel quick sort algorithm, you can sort through parallel quick sort to improve the speed

jacobi迭代求解椭圆方程，主要是用mpi进行并行计算，采用的是重叠边界网格，这个是重叠了一层，通信采用的是非阻塞型的通信函数，方程采用的是二维的poisson方程。

这是一个表达式程序，主要用以实现从前缀表达式到后缀表达式的转换功能-This is an expression of procedures, mainly used for the realization of the suffix prefix expression expressions of the conversion function

ram的读写，使用状态机完成，两片ram实现乒乓操作-ram read and write, using the state machine completed, two ping-pong operation to achieve ram

附件代码实现了基4FFT的碟形单元运算，是FFT算法的核心部分，并且此碟形单元运算是基于浮点运算的-Annex code base of the dish 4FFT computing unit is the core of the FFT algorithm, and this dish is based on the computing unit of the floating-point operations

由于一个数值问题的精确解往往事先不知道，而用数值方法求出的计算解的误差又是不可避免的。因此，数值解是否失真，如何判断──即误差问题，成为大家所关心的重要而又困难的问题，本章只介绍了误差的基本概念和数值计算的若干原则，这对处理数值计算问题是必需的，但是仅这些还远远不能解决工程和科学计算中更为复杂的误差分析问题，还需专门分门别类地进行研究。-as an accurate numerical solution of the problem often did not know in advance, and the numerical methods used to calculate the solution sought by the error is inevitable. Therefore, the numerical solution of whether distortion, how to judge-- namely error, as we are concerned the important and difficult issues, this chapter presents only the basic concept of error and numerical calculation of certain principles, which deal with numerical calculation is necessary, but they are far from alone can not solve engineering and scientific calculations more complex error analysis, specialized categories needed to conduct research.

并行算法下的including实现。使用mpi再smp环境下 -Under the parallel algorithm including realize. Use mpi re-smp environment

用此程序可以方便的查讯日期和星期几，还可以查当天和未来几天的．-This procedure can be used to facilitate inquiry date and day of the week, you can check the same day and the next few days.

一些mpi并行计算的源码,和论文,包括一些常用的算法示例-Some mpi parallel computing source, and papers, including some examples of commonly used algorithms

线性方程组Jacobi迭代的并行求解。附件数据文件是4阶方阵的算例。调试A*x=b，A为n*m矩阵的话，数据文件第一行n m,后附[Ab]矩阵（n*(m+1)）
