[Pw_forum] image parallelization for phonon calculations

[IYAD AL-QASIR]

Hello All,
I am trying to perform in parallel phonon calculations  using ph.x.

I used the command
mpiexec -np 12 ./ph.x -nimage 3 -npool 2 <input.in> input.ph.out

but I got the message the "*image parallelization is not permitted*"

Any Hint?

Thanks
