P2y stop with segmentation fault

Post by sdwang » Wed Sep 11, 2019 4:09 am

Dear developers,
I am using Yambo-4.4.0 to generate SAVE file, but at the end of the process, it stops with 'segmentation fault'. And I tried to do yamb -i, and it works without any error(I used enable-uspp configuration).

Hi Shudong,

thanks for reporting.
Two main comments:
- USPP are currently supported as a preliminary feature, only for HF and with limited symmetry support;
this means USPP are not yet production-level, but mostly usable for testing
- Concerning the problem you are experiencing, it would be very useful to have an input to reproduce (and possibly solve)
the problem

take care

Dear Andrea,
I removed uspp option and now it works.
Thank you!

Dear dxevelopers,
I am using Yambo-5.2.0 to generate SAVE file, but at the end of the process, it stops with 'segmentation fault'.
It seems i get some problem with IGK arrays.

Code: Select all

 <---> DBs path set to : .
 <---> detected QE data format : qexsd
 <---> == PWscf v.6.x generated data (QEXSD fmt) ==
 <---> Header/K-points/Energies... done
 <02s> Cell data...
 <02s> [WARNING] Two or more crystal structures fit the given cell done
 <02s> Atomic data... done
 <03s> Symmetries...[SI no]...[I yes]...[-I no]...[TR yes]
 <03s> XC functional...Slater exchange(X)+Perdew & Zunger(C)
 <03s> EXX fraction...:  0.000000
 <03s> EXX screening...:  0.000000
 <03s> K-points mesh... done
 <04s> RL vectors... done
 <04s> IGK arrays...zsh: segmentation fault (core dumped)  p2y
I don't know how to solve it.
Thanks!

Dear Jerry,

can you please post your nscf input file?
Other suggestion is to try to use a more recent release of QE.

Best,
Daniele

Dear Jerry,

it seems your input files runs correctly with me using qe-7.2 + yambo-5.2.1 both compiled using gfortran.

From your input file: you have quite a lot of kpts, which can make the G-vector grid and maps quite large.
Have you checked the limits of your shell (zsh if I get it right), e.g. using ulimit or similar ?

Dear Ferretti,

I changed my ecutrho in qe computation and solve the problem.

Thanks!
