[QE-users] RE： Error happens after setting max_seconds in turbo_davidson.x

[Iurii TIMROV]

Dear Weijie,

I made a quick test using example 8 of TDDFPT and the restart works fine. Therefore, try to use QE6.7 and try example 8. If it works for you, then try it for your system (for the sake of testing reduce the cutoff, num_eign, num_init, max_seconds).


Greetings,

Iurii

Dear Iurii,

Thanks for your reply and reminder. I am using QE 6.5. And you can see the input & output files in:

https://drive.google.com/drive/folders/1djSkUZ2MkF0nKNntQgZJ8wt3b3IpmHs-?usp=sharing

I am sure there is enough space and time for writing data for restart files after double check.


Best,

Weijie Zhou

Please read carefully how to ask questions on the pw_forum: https://www.quantum-espresso.org/forum


In particular:

- which version of QE do you use?

- provide all input and output files (so that we can reproduce your problem)


Moreover:

- make sure you have enough disc space to write the data for restart

- make sure that the code has enough time to write the data to disc (i.e. compare max_seconds with the total time of the job)


Once all this is clarified, the QE developers can have a closer look at your problem.


HTH

Subject: [QE-users] Error happens after setting max_seconds in turbo_davidson.x

Dear QE users,

I am trying to use "restart" function for turbo Davidson calculation. So the "max_second" was specified in the input files of turbo_davidson.x which is shown as below:

&lr_input
    prefix='Mo_O',
    outdir='../../../tmp_Mo8O26_davidson_size20_e-4_nosmearing_T2'
    restart=.false.
    max_seconds = 144000,
/
&lr_dav
if_dft_spectrum= .false.
num_eign = 16,
  num_init = 32,
  num_basis_max = 80,
  residue_conv_thr = 1.0D-4,
  start  = 0.0,
  finish = 6,
  step   = 2.0D-4,
  broadening = 0.005,
  reference = 0.5,
  p_nbnd_occ  = 8,
  p_nbnd_virt = 8,
  poor_of_ram  = .false.
   poor_of_ram2 = .true.

But error happened at the end of calculation (max_second is reached) when writing data for restart. The error message:
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
    Error in routine diropn (22):
    error opening ../../../tmp_Mo8O26_davidson_size20_e-4_nosmearing_T2/Mo_O.restart_davidson_vec_b.3
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     stopping ...

It will be very appreciated if you can solve my problem for me. Thanks.

Best,
Weijie Zhou
