Dear All I hope everyone is doing great. I am trying to run anisotropic el_ph calculation, but it gives me a headache :) . What type of error this is and how can I fix it? I guess it is related with memory. Error in routine kernel_aniso_iaxis (1): Error allocating akeri task # 0 from kernel_aniso ...

Dear H. Lee


Ok. Thank you. I will use 24 processors and see what happens. Otherwise, I will change the parameter. Do I have to go to epw_readingf90 and change max_memlt and then recompile epw?

Hi Ilias Have you used eliashberg = .true. ? If so, you have to specify laniso = .true. to calculate anisotropic superconductivity, and liso = .true. to calculate isotropic one. If you have not used eliashberg = .true. flag, I think you are calculating the isotropic superconductivity. Sincerely ...

Dear All I hope everyone is doing great. I was running Eliashberg anistropic calculation and it crashes at the beginning of solving this equation for on an imaginary axis with the following errors: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% task # 0 from ...

Hi Hari Here is the input &inputepw elph = .true. kmaps = .false. epbwrite = .true. epbread = .false. epwwrite = .true. epwread = .false. nbndsub = 30 ! bands_skipped = 'exclude_bands = 1-10' wannierize = .true. num_iter = 300 proj(1) = 'l=0; l=1' proj(2) = 'l=0; l=1' wdata(1) = 'bands_plot = .true ...

Dear Hari

Thank you very much! I have not used eliashberg to calculate lambda. I used the normal method (elph=.true.). Do I have to use eliashberg=.true. variable to get information about the band contribution to lambda?

Dear All

I hope everyone is doing great. I have calculated lambda ( ele-phon coupling constant) and I would like to know which bands and k-points are contributed more for lambda. How can I find this information? Thank you.

Dear All

I hope everyone is doing great. EPW is running with np = npools for nscf and epw run. I am wondering if it is possible to run with the same processor but using npools equal one. In my case, the HPC I am using is fast when npools are set to equal to one. Thank you.

Dear Paudyal

Thank you so much! I miss to open that link.

Dear All When I run epw, I come up with the readdvscf error as indicated on the subject. I tried to look for readdvsc.f90 file in EPW/src/ folder but there is no file in that name. On this forum before 4 years ago, the same error had been discussed by Jiachen and Prof. Samuel, and the solution was ...
