[QE-users] Abnormal stopping in phonon calaculations in ph.x

[王绍菲]

There must be someone who knows this kind of problem.

when i calculate the phonon band structures by using ph.ix, i confront with " 12 total processes killed (some possibly by mpirun during cleanup)"

the end of scf.out has got "convergence has been achieved in 14 iterations"

but the phonon calculation are wrong :

     Check: negative core charge=   -0.000002
     Message from routine divide_et_impera:
     suboptimal parallelization: some nodes have no k-points
