p2y error with large k-points

Post by will » Thu May 31, 2018 9:20 am

Dear all,
I came across a problem when using p2y to convert pw data.In the case of samll kpoints,everything is fine.However,when the kpoints is 20*20*20,it reports error as follows:
__________________________________________________________________________________________

<---> Index file set to data-file-schema.xml
<---> Header/K-points/Energies... done

Dear Andrea,
Thanks for replying.The system I'm calculating is the simple silicon.I have attached my input files and yambo config.log.Yambo version is 4.2.2.
For p2y, p2y -H
_______________________________________________________________
This is p2y 4.2.2 rev.110
P(Wscf) 2 Y(ambo) interface

-h :Short Help
-H :Long Help
-N :Skip MPI initialization
-F <opt> :XML index file name
-O <opt> :Output directory
-U :Do not fragment the DataBases (only for serial runs)
-b <int> :Number of bands for each fragment
-a <real> :Lattice constants rescaling factor
-t :Force use of spatial Inv. instead of Time Rev.
-n :Force no symmetries
-w :Force no wavefunctions
-v :Verbose wfc I/O reporting
