alpha2f.x did not work since MPI parallelization of tetrahedron
alpha2f.x did not work since the commit 12c2f58b on 2023/11/24.
Because the partial DOS routine to compute \alpha2F(\omega)
is MPI-parallelized, nks
should be set for the compatibility.
Also, nproc
> 1 causes error in the parallelized PDOS routine used in this program.
Therefore nproc
> 1 is rejected (it may be OK because the calculation is light).
