[QE-users] Seg. Fault in the writing .save step

[Mahmoud Payami Shabestari]

Dear Paolo,

Hi again.

In non_dft+u calculation, I have no SEG. FAULT problem.

Is cp.x inconsistent with dft+u?



Mahmoud





Dear Paolo,
Hi.
Thank you so much for your reply.
1- I am using the cp.c included in QE-6.7. Yes, I am using DFT+U.
2- The Intel compiler 2018 update 4 is used for building.


Thank you again.
Bests,
Mahmoud






Hi Mahmoud


1.  are you running CP (which version?) with DFT+U?
2.  which compiler are you using? several old versions of the Intel compiler 
have problems with that part of the code

Dear QE users,


I am running cp.x for a given input file. The run is completed but when the 
program starts to write   .save
files, I get the following SEG. FAULT:

It should be mentioned that:
1)- the "ulimit -s unlimited" recipe has already been applied.
2)- The Example-1 of cp.x for SiO2 has been run successfully without such an 
error.


Any comments is highly appreciated.
