Error with epwread = .true., "Restart is done without reading PWSCF save file."

Post by psharma »

Hi all,

I'm trying to restart a calculation where I believe it should read previously written files from the disk (all needed files such as crystal.fmt, epwdata.fmt, etc are present in the disk). But I'm getting the following statement printed in my output which I don't understand
------------------------------------------------------------------------
RESTART - RESTART - RESTART - RESTART
Restart is done without reading PWSCF save file.
Be aware that some consistency checks are therefore not done.
------------------------------------------------------------------------
My first run (Pd_3.epw.in) is done with parameters
elph = .true.
epbwrite = .true.
epbread = .false.
epwwrite = .true.
epwread = .false.
wannierize = .true.

and then second run (Pd_4.epw.in) with

elph = .true.
epbwrite = .false.
epbread = .false.
epwwrite = .false.
epwread = .true.
wannierize = .false.
Attached zip folders has input and output files for more details. I'm using EPW v.5.4.1.
I would appreciate any help in understanding this issue.

Thanks in advance!
Prachi.

Hi Prachi,

This is just a message in a restart calculation from https://gitlab.com/QEF/q-e/-/blob/devel ... pw.f90#L92. If your first step is done correctly, and corresponding files are written with no issue, no do not need to worry with this message.

Happy EPWing,
Hari
