mpiexec

Hi,
My PETSc based application can work correctly, but after system updating
when I use the same commands:
>lamboot
>mpiexec -np 4 application

It seems only one processor works. Then I  test it using the following code,

**********
PetscErrorCode ierr = MPI_Comm_rank(PETSC_COMM_WORLD,&rank);CHKERRQ(ierr);

 COUT << "This is processor : " << rank << ENDL;

Use command: mpiexec -np 4 application,
The output is:
This is processor : 0
This is processor : 0
This is processor : 0
This is processor : 0
*********

Thanks for your help.
