error when running eliashber anistropic calculation

[zega14]

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 eliashberg_aniso_iaxis : error # 1
Error allocating df1
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% task # 62 from sum_eliashberg_aniso_iaxis : error # 1
Error allocating wesqrt
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

task # 58
from sum_eliashberg_aniso_iaxis : error # Error allocating wesq %% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%



Any idea how I can fix it? Thank you.


Sincerely, Zegnet

Dear Zegnet:

The allocation error very likely results from the memory shortage.
If you don't want to change the computational parameters, one of the simplest ways is to increase the memory per MPI task by using the smaller number of MPI tasks per node.

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?
