[Pw_forum] Compiling QE-6.0 on IOLENGTH=4 machine

Dear QE Users,

I have compiled QE-6.0 on a linux machine with intel-2016.4.258. The IOLENGTH on this machine is 4. So I changed the DIRECT_IO_FACTOR in the /Modules/io_files.f90 from 8 to 4. However, a simple self-consistent run crashed with the following error:

     from davcio : error #        10
     error while writing from file "/scratch/vaskarpo/qe-6.0_LENGTH4/default_phonons/1/./SnSe.wfc19”

Are there other parts of the QE code that use IOLENGTH=8 (other than EPW and PP) explicitly without using DIRECT_IO_FACTOR as a parameter? In other words, are there other parts of the code that needs to change in order to get it to work on the above machine?

Thank you,

Vahid
