[QE-users] Save time in Running ph.x

[LEUNG Clarence]

Dear QE  users,

Recently, I use ph.x to calculate Complete phonon dispersion, and it took a long time. My system consists of  23 atoms and ( 6, 6, 1)  uniform grid of q-points.

I noted that ph.x may take advantage of MPI parallelization on images, plane waves (PW) and on kpoints (“pools”). How can I use this method to save time? My cluster consists of 5 nodes, each node has 28 cores and 56 threads.

Thanks.
