Hi, I believe the code is crashing because the input temperature at which the anisotropic Eliashberg equations need to be solved is very small (0.0005 K) and then the number of imaginary frequency points nsiw is very large (it this case more than one million since it is printed as ****). WRITE ...

Hello! I am testing the calculations by EPW. The problems is like below, when doing the procedure "Solve anisotropic Eliashberg equations on imaginary-axis", it output like "BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES". I also try changing the etf_mem from 0 to 2, it does not work. Can ...

I am having some similar issues can you please tell me what changes you made? What compilers you used and no. of processors etc. ?

Thanks a lot in advance.

Hello, I solved my problems by change to the norm-conserving potentials (XX.pw-mt_fhi.UPF).

Hello, From the different report, it seems there might be an issue with intel18/mkl18 and associated impi. Can you try compiling with an older version of intel/mkl/impi. For example 17 is tested by the automatic test farm and should work ? Best wishes, Samuel Dear admin, Again, thanks for your ...

Hi, It is difficult to identify the possible cause without any additional information, such as the input file. Is there no error file too? Also, have you been able to run some of the examples / tutorial successfully? Best Carla Dear Carla, By changing the ways to compile the code, now I manage to ...

Dear admin and users, I tried the calculations using epw.x. Things are fine at the beginning. However, it then crashes without giving any error messages. The bottom of the output is shown below1. I think the wannier step is fine, since it output like below2. Can you please tell me what should I do ...

try changing the etf_mem from 1 to 0 and request more memory from your computational node.

Dear Andrei,
Thanks a lot. Your answer perfectly solved my problems.
