[Pw_forum] Phonon calculation takes much time...................

[zafar rasheed]

Dear Paolo Giannaozzi
I am calculating phonon calculation for ZnS using 8 atoms. But it take a long time nearly 7 days to compleet calculation. I have dual core 1.866 GHz laptop with 2 Gb RAM. Am I putting some wrong parameter due to which this calculation is too slow. For 2 atoms calculation it take 6 to 7 hours.
