QE 6.8 and Yambo 5

[chwolf]

Hi guys,

is the new QE not compatible with Yambo 5? The input variable wf_collect has now become obsolete but p2y complains:

Error in routine p2y_init (1):
QE format not recognised/compatible (was wf_collect set to true?)


My versions: Program PWSCF v.6.8 starts on 30Sep2021 at 22: 6:28
This is yambo - MPI+OpenMP+SLEPC+HDF5_MPI_IO - Ver. 5.0.4 Revision 19595 Hash 896bffc02

Any help is as always much appreciated!

Best,
Chris

Ok, after deleting my temp folder and running it again it seems to be working, so don't mind my first post!

Hi Chris,

good to hear everything is solved!.
Indeed, Yambo and QE-6.8 are compatible.

Dear Andrea,

thank you for your reply - unfortunately there still seems to be *some* hiccup in my system. I realized that I loaded qe-6.6 in the previous test by accident (smart me...) The following input still does not work for QE 6.8 and Yambo 5.4 for me:

again it works flawlessly with QE 6.6 using exactly the same input

I did a diff on the xml files because sometimes the format changes but in this case that does not seem to be the culprit here:

Any idea what I should be looking for..?

Dear Chris,

I gave a try to your input files and I was not able to reproduce the problem.
I have run pw using gnu 7.3.1, and then used yambo 5.0.4 (both gnu and intel 19.1.0.66) and it works well...
I have run first a scf and then a nscf calculation. Attached the precise input files I've used.

Sorry, I should not install yambo 4 in a folder called yambo 5 and vice versa, I have no idea how that happened but finally, the mystery is solved - I apologize for keeping you all updated on my stupid journey

Somehow the version numbering 4.5.x and 5.0.4 really scrambled my brain....

Chris

[andrea.ferretti]

ahahah...
let's put it in this way: we had the opportunity to run some extra checks and everything works fine

Sorry I sent you on this journey Andrea, I hope I can make it up to you at a Yambo school in the future, I promise I won't forget about it!
