平均值，调和中项，等比中项标准差等数值的计算代码-Arithmetic Mean, Geometric Mean, Harmonic Mean & Standard Deviation

pthread 在linux下高性能并行计算平均值与方差。-pthread linux parallel computing mean and variance.

此源码为用Intel TBB并行开发工具实现计算平均值的并行程序，为用C++编写的，但需要有Intel TBB的插件，具体可以安装Intel Parallel Studio嵌入VS2010或2012中使用-This source is using Intel TBB parallel development tools to achieve a parallel program to calculate the average, for the use of C++ written, but r
