[mpich-discuss] error recieving

3 Jan 2014


      Hi.
What's wrong with my code?

   1.   char send_buf[12]  = "hello world";
   2.   char send_buf2[12]  = "hello iran";
   3.   char recv_buf[10];
   4.   int i;
   5.   for(i=0;i<10;++i)
   6.   if (world_rank == 0) {
   7.     MPI_Send(send_buf, 12, MPI_CHAR, 1, 0, MPI_COMM_WORLD);
   8.     //MPI_Send(send_buf2, 12, MPI_INT, 1, 1, MPI_COMM_WORLD);
   9.   } else if (world_rank == 1) {
   10.     MPI_Recv(recv_buf, 12, MPI_CHAR, 0, 0, MPI_COMM_WORLD,
   MPI_STATUS_IGNORE);
   11.     printf("Process 1 received %s from process 0\n", recv_buf);
   12.   }


Run-time errors are very hard to fix!Help me please

Thanks in advance
