[Pw_forum] How to reduce I/O in phonon calculation?

[Yue-Wen Fang]

Dear all,

As known to all, phonon calculation generate amounts of data and requires
well-built I/O, my question is are there some effective methods implemented
in the latest versions to reduce the amount of I/O by ph.x?

BTW, although there is a tag "reduce_io" in ph.x, Prof. Paolo has ever said
in the mail-list that it only affected the first step in scf calculation
several years ago.
