Dear QE users,
I have a question about phonon procedure ph.x
As I understood from manual and tutorial, ph.x use linear response method 
(DPFT). But computational efforts of this method are very sense to quantity of 
atoms in supercell. Can I use ph.x for phonons calculation of frequencies for 
system Fe-V with 54 atoms (full interval of different concentrations)? Or 
should I use another additional program, for example, using small displacement 
method?
What about hardware parameters, I work on ?Tornado SUSU? Supercomputer ( 
http://supercomputer.susu.ac.ru/en/computers/tornado/ ). Quantity of computing 
units/processors/cores: 480/960/384/29184
Type of processor:      Intel Xeon X5680 (Gulftown, 6 cores with frequency 3.33 
GHz) ? 960 pcs.
Type of coprocessor:    Intel Xeon Phi SE10X (61 cores with frequency 1.1 GHz) 
? pcs.
RAM:    16.9 TB
Thank you.
Buldashev Ivan, student.
