- Hi,
As for the unexpected termination of the job, we see the error message: "KILLED BY SIGNAL: 9 (Killed)" indicating out of memory. I guess that your computational environment does not have an enough memory to complete the runtest.
Regarding "runtestNEGF.result", your part of runtestNEGF.result agrees with my result as shown below.

Total elapsed time (s) 1128.47
The reason why we see the large differences is that the relevant codes for the NEGF calculations in the patch have been modified for the calculation of the boundary. So, the differences are expected ones.

- Dear Prof. Ozaki,
Thank you very much for your comments. It was very helpful.
I did the runtestNEGF with two core (MPI) without OpenMP option and I noticed that the RAM is approximately fully occupied at 10th dat file without killing process (at the beginning of the run in contradiction to the previous times) and I conclude I don't have enough RAM memory.
I had a question regarding some differences being more than last seven digits. According to your results I noticed it is not a problem.
Thanks a lot again, Mehdi Vejdanihemmat
