Re: Different scf behavior between serial and parallel ABINI

Dear Jordan,

I carefully looked into log files of serial and MPI runs.

All of their structures are identical at the end of relaxations.

Thank you very much!

Best regards,

Re: Different scf behavior between serial and parallel ABINI

Dear Jordan,

Sorry, I misunderstood my log file in.

LOBPCG algorithm,wfoptalg = 14, was used.

Best regards,

Re: Different scf behavior between serial and parallel ABINI

Dear Jordan, Thank you very much. Just to make sure, I have a question. The jobs were done with PAWs. According to log files, wfoptalg = 10, which is standard state by state conjugate gradient algorithm, was used for MPI and serial ABINIT calculations. While I used "wfoptalg 4" in an input...

Different scf behavior between serial and parallel ABINIT

Dear all, I am relaxing structures for barium titanate using ABINIT-7.10.4. When I use serial and parallel ABINIT with npband=4, npfft=2, npkpt=4, and para_kgb=1, the number of scf steps with serial ABINIT is larger than that with parallel ABINIT. I expected that scf convergence would be identical. ...
