爱尔兰公式恩格赛特公式的实现，可以求出通信网的阻塞概率-Engel Dorset formula to achieve, can find out the network blocking probability

排队算法的仿真实现，可以用于通信系统中基于M/M/S排队阻塞率计算的实现，-The queuing algorithm simulation to achieve, can be used for the communication system based on the M/M/S queuing blocking rate achieve

以二元运算为例，用阻塞型点对点通信函数实现了MPI_Scan的功能。-In a binary operation, for example, by blocking peer communication function implements the MPI_Scan function.
