[Pw_forum] Problem with parallel phonon calculation using image method

[David Miller]

actually, I typed wrong command in my earlier mail. My SCF calculation was indeed performed using 64 processors as:



aprun -N 8 -n 64 ./ph.x -npool 4 < ph.in > ph.out

Next, I tried the image method for phonons using:

aprun -N 8 -n 640 ./ph.x -nimage 10 -npool 4 < ph.in > ph.out



Thanks,

David
