[Pw_forum] time for calculation of el-ph interactions of graphene supercell

[L.F.Huang]

Dear Paulatto:
  I am sorry that I could not get exactly what you mean when you mentioned
"if you do your scf calculation using the wf_collect=.true. option you can
(usually) post-process the data with a different parallel configuration".
Does "wf_collect=.true." is related with the calculation of EPC ? I have
read throug some documents for inputs, but can not find that relation.
Could you please teach how to use "wf_collect=.true." in the calculations
of el-ph interaction? Or could please you tell me some examples?
  Additionally, the calculation of el-ph interaction in my case finally
complete in this morning, 5 days elapsed.

Thank you very much Paulatto! Also Thank you for your lecture given in
Shanghai China this July!
Best Wishes!
Yours Sincerely
L.F.Huang
