I have been using BURAI GUI of Quantum ESPRESSO to calculate the optical properties of ZnSe quantum dots. But first I wanted to calculate the electronic band structure. After running the calculation for about 14 hours it stopped after giving me an error:

     Band Structure Calculation
     Davidson diagonalization with overlap

job aborted:

C:\Users\aman\Desktop\quantum-espresso\BURAI1.3_Windows\exec.WIN\qe\pw.exe aborted the job. abort code 1

Can anyone tell me what is wrong or how to fix this? I was able to do geometrical optimization and a DOS calculation.

My input file(this might be a bit different as this is the input file from BURAI, not from QE directly)-

    $\begingroup$ Almost certainly no, nobody will be able to tell you what went wrong with this output. This is just the program telling you it is having to stop because an unrecoverable error occurred, it probably says nothing at all about what went wrong - unless "error 1" has a meaning. Is there no other output reporting an error by the code? $\endgroup$

  • $\begingroup$ It also said something about not being able to import wfc8 file. And I actually thought that there was something wrong with my environment and provided this, would my input file help? $\endgroup$ Jun 12 at 8:38

    $\begingroup$ Edit the question to show the error message relating to the wfc8, that is the thing that might allow a Quantum Espresso user to help you, and that is the real error message. But that won't be me, I'm a programmer, I can tell you all abut MPI_Abort, but not what is causing Quantum Espresso to call it. $\endgroup$

  • $\begingroup$ Hi! have you tried doing the series of calculations you're doing on a smaller system (like a ZnSe unit cell), inorder to know if your setup consisting of BURAI and QE is proper? $\endgroup$ Jun 13 at 17:52
  • $\begingroup$ Apart from that how did you go about calculating "the band structure of a Quantum dot" ; could you calculate the band structure of a 3d aperiodic system using QE. I would like to see your input files if you're willing to share :). $\endgroup$ Jun 13 at 17:58

$\begingroup$

This may not be the issue, but the manual says the max_seconds keyword under &control is maximum CPU time, not wall time, the calculation will run. So if you ran the calculation on even two CPUs, it would likely die if it ran for roughly half the given time, so 43200 seconds or 12 hrs.

So your calculation may have just timed out. In most programs, an abort in an error message means the job was cancelled by the user or ran out of time unexpectedly.
