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