在软件MAX+plus II环境中，设计了一台RISC模型机，具有以下功能：输入包含10个整数（无符号数）的数组M，按从小到大的顺序输出这10个数。-In terms of software MAX+ Plus II environment, the design model of a RISC machine, has the following features: input contains 10 integer (unsigned number) of the array M, according to the order from small to large number of the output of these 10.

MPI实现四个进程以上的Jacobi迭代,进行连续四次迭代后选择两进程所处理数据交界处8×8子矩阵进行输出-MPI realize more than four Jacobi iterative process, carried out four successive iteration process after the selection of two data processing at the junction of 8 × 8 sub-matrix output

实现矩阵乘的并行算法源程序，拿来与大家分享-Matrix by the realization of the parallel algorithm source code, used to share with you

这是一个非常好的精简的并行程序库，它底层使用MPI作为驱动，只使用了简单MPI API，从而兼容各种MPI 实现产品。这个类库的特定是实现了数据并行和任务并行-This is a very good parallel to streamline the procedures, which use MPI as a bottom-driven, use only a simple MPI API, thereby various MPI compatible products. The library is the specific data parallel and parallel tasks

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.

蚁群算法源代码，无须修改便可以直接编译执行-Ant colony algorithm source code, no need to change the implementation can be directly translated

本人写的一个快速排序的程序，同时写出了用openmp进行的并行计算程序，并且对于串行和并行进行了时间的比较，希望对于初学openmp的同志有所帮助！-I was sort of a fast process, at the same time to write with the openmp parallel computing procedures, and serial and parallel for a comparison of the time, I hope for the beginner gay openmp help!
