The problem with this program is that it does not call
MPI_Finalise() and also a.exec() may not be returning 0.
Every MPI program must call MPI_Finalize before exiting.
You could have something like this.
int ret = a.exec();
MPI_Finalize();
return ret;
This might help you figure out where the error lies. Also for
returning values you might want to read MPI_Finalize() man page.

- Initial code:
- int main
- {
- MPI_Init( &argc, &argv );
- KApplication a;
- Backprop *backprop = new Backprop();
- a.setMainWidget(backprop);
- backprop->show();

- after few seconds it finish and in console the massage

- One of the processes started by mpirun has exited with a nonzero exit

- If your process did not finish in error, be sure to include a "return
