MPI_STATUS_SIZE is an integer parameter defined in an MPI module. It is likely that you forgot a USE the appropriate MPI module. Note, IIF your use of MPI_STATUS_SIZE is located within a Fortran include file (*.fi) for the purpose of including COMMON blocks, the source code procedure ...

MPI_RECV(BUF, COUNT, DATATYPE, SOURCE, TAG, MPI_COMM_WORLD, STATUS, ierr) SOURCE是消息来源的进程编号; STATUS是返回状态。 三、一个接收和发送的例子 下面测试一个简单的例子:我们开16个进程,然后每个进程中,设置一个变量 a,然后在第二个进程中令 a = 1,再把第二个进程中a的值传给第14个进程。
