ABINIT Discussion Forums

Dear ABINITers,

I have compiled ABINIT 6.6.3 using Intel compilers, MKL, and Intel MPI. When I now try to run an input file that used to work correctly with version 6.0.3 on a different machine, I get segmentation faults in the last step of the GW run. As the calculation is performed in a spin-polarized way, that is nsspol 2, I changed bdgw from

bdgw4 380 384

to

bdgw4 380 384
380 384

I don't get this error with nsspol 1. The problem occurs with both version 6.6.3 and 6.4.3. I have also tried to reduce the optimization to standard level. What else can be the source of this error? I attached the input and log file.

Thanks!

Best regards,
Martin Haeufel
