Dear users:
I am a very confused question: Is the phonon code (ph.x) really
implemented in parallel version?
since the phonon computational time usually is intolerable,for example,
the task was not completed
when I calculated the phonon dispersion of superconducting material
LaOFeAs. Furthermore, the speed of computation shows
no difference when I used 32 CPUs from that when I only 8 CPUs. Also, the
dynamic matrix files *.dyn(1-n)
are generated one by one, totally different from SCF wavefunctin files
which are generated parallelly(like
*.wavfc1,*.wavfc2, ......, *.wavfc8 in case of 8 CPUs parallelization
sheme)
thanks a lot
