Dear Elie,
I have tried to run your test using the latest development version of QE on Gitlab and it works fine. I run it on my workstation with 4 cores. In your case you have this: Parallel version (MPI & OpenMP), running on 48 processor cores Number of MPI processes: 24 Threads/MPI process: 2 So please try to do the following: 1. Run the calculation using the latest development version of QE with 48 cores and 48 MPI processes (i.e. Threads/MPI process = 1) 2. If the above test is successful, then try to run with the latest development version of QE with 48 cores and 24 MPI processes (i.e. Threads/MPI process = 2) Please report what you obtain.

Please let me know if you find anything. I will try QE-7.2 as well.

Please try also QE v7.2 just to be sure.

I am using QE-7.1. I am not sure it is related to the version of QE. In any case, I will send through a shared folder the input and output files. Maybe, there is something I missed. regards ________________________________ From: users <[email protected]> on behalf of Timrov Iurii via users <[email protected]> Sent: Friday, June 30, 2023 12:05 PM To: Quantum Espresso users Forum <[email protected]> Subject: Re: [QE-users] Turbo_eels.x crashing for bulk MoS2 Dear Elie, Which version of Quantum ESPRESSO are you using? Please try the latest one v7.2. If the problem is still there, please report the input and output files (via a shared folder, not attachment).

In the scf caluclation , I have included the van der Waals corrections as vdw_corr='DFT-D'.
