[Pw_forum] image parallelization for phonon calculations

[IYAD AL-QASIR]

Thank you Prof. Giannozzi,

Actually, the message "*image parallelization is not permitted*" appeared
when I run pw.x ( sorry for the confusion in the last email)
mpiexec -np 12 ./pw.x -nimage 2 -npool 3 <scf.in> scf.out

So After i ran pw.x with niamge=1, I tried to run ph.x but using nimage >1
,
mpiexec -np 12 ./ph.x -nimage 2 -npool 3 <ph.in> ph.out

but I got

from d_&_i : error #         1
      some nodes have no k-points

Thanks
IYAD
