MPI-2的解决方案 •对通信域进行扩展 –组内通信域–组间通信域 •具体实现方式 –动态派生进程（有父子关系）–独立进程间通信（C/S关系）–Socket通信（转换socket通信）组间通信域的点到点通信 例子 •MPI_SEND(buf,count,datatype,dest,tag,intercomm)•与组内通信的不同：1dest的含义；2intercomm ...

发送的消息内容是:从 message 参数处开始的一个 MPI_Datatype[count] 数组。 其中,count 是数据元素的数量(数组长度);MPI_Datatype 为其类型,基本就是和 C 的简单数据类型一一对应: MPI_Datatype对应的 C 数据类型 MPI_SHORT short int MPI_INT int MPI_LONG long int MPI_LONG_LONG long long int MPI_...
