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 Soheil Hooshdaran
