快排的并行实现，使用openMP,程序自动生成随机数，分别使用单线程和多线程排序，并比较最后的结果-quick sort based on openMP

采用了多线程的pi值计算，效率比单线程高-Using a multi-threaded pi value, high-efficient than single-threaded

一个基于OpenMp并行编程的实例，基于多线程，多线程比单线程下节省运行时间的典型例子。算法内容主要是计算矩阵乘积，再求个元素和。可通过"任务管理器"-"性能"查看运行在多核上。-Typical example of a parallel programming based OpenMp instance, save run time based on the multi-threaded, multi-threading than single-threaded. The algorithm

代码主要实现了单线程、多线程求π的计算方法，在集群上运行，比较时间。-The code mainly implements the single-thread, multithreaded method of calculating π, runs on the cluster, compares the time.
