A parallel cubic response calculation

In this example of a DALTON.INP input file, we assume that the program has been compiled with MPI options, and request a SCF calculation of the second hyperpolarizability ($\gamma_{xxxx}$) using the cubic response solver of the RESPONSE program. No two-electron integrals will be stored on disc in any part of the calculation. The number of nodes used is determined when submitting the job, and how this is done depends on the computer on which the job is run.

All treatment of symmetry, as well as the Hartree-Fock occupation, is automatically taken care of by the program, and we thus only need to specify that we are to do a Hartree-Fock calculation.
