Hello,
I try to calculate GW corrections and at the end of the run I receive the error message:

Fortran runtime error: End of file

--------------------------------------------------------------------------
mpirun has exited due to process rank 0 with PID 12502 on
node QuanCal exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).


Is this because of the double slash // in the code? Or do I have to look for another problem?

Thanks and regards

Dear Stephan,

Did you compile the code with gfortran ?

Dear Stephan,
it looks that for some reason the calculation of the screening was not complete and you have corrupted files.
Yes please post your inputs and reports and standard ouptuts if your calculation, so we can have a look.
Best,
Daniele

Dear Stephan,
the problem is due to that you are calculating the screening for 1 q points only:

% QpntsRXd
1 | 1 |

while you have 288 Kpoints and I do not now many q points to integrate the Bz.
In order to perform the integrations over the Bz needed in the GW you need to calculate the \eps_GG'(q) for each q point (that should be the default in input).
Using the same resources (4 cpu) you are using now your calculations the computation time will be very large (about 11min for each q point).

Beside that: please note that you are calculating QP corrections for a lot of states (more than 8 thousands and this is the reason for the large cpu time to caluclate the HF correction) do you need all these states?

Best,
Daniele

Hi Daniele,
thank you for your reply. In the end I want to calculate the dielectric function in RPA with Quasiparticle energies (RPA-GW).
Therefore I produce the QP-database. If I want to reduce the number of QP I suppose it is the best idea to keep the number of k-points and to reduce the number of involved bands, right?

Thanks and Regards
Stephan

Dear Stephan,
I do not know the system you are studying, generally RPA+GW it is not a good approximation for optical spectra in presence of excitons.
Contrary in metals a simple RPA could be satisfactory, in any case in order to correct the energy levels to be used in RPA, a solution to try is
to look for few bands and see if you can then interpolate the corrections for the other bands you need to include in the RPA.
IN order to that you can use the variable" where the first number is the scissor to be applied to the gap and other two are the stretching or shrinking of valence and conduction bands.
Best,
Daniele
