Hang MPI process when steps in wannier_run

#1 Post by zongxiang_hu » Thu Jun 24, 2021 1:00 pm

Dear VASP developers,

I have trouble in generating MLWF by using wannier90 interface with vasp.6.2.x. I find that other steps depending on vasp only can run correctly and wannier_setup also can run correctly, but processes hang when subsroutine wannier_run is runing. I check occupancy of all processes find that all processes have 100% occupancy but I get nothing waiting for a while.
I wonder if compiling of libwannier.a causes this proplem?

Kind regards,

Have you seen this post. Perhaps your issue is related.

If not could you provide a full example (POSCAR, INCAR, KPOINTS, POTCAR) to reproduce the issue, please?
