[Pw_forum] problem during pw4gww.x calculations

[Mortaza Aghtar]

Dear All,

I want to run GW calculations for boron-nitride sheet. First I ran a scf
calculation
for only the gamma point. Then I ran pw4gww.x to get the wannier's
matrices. But
after some steps I get this error in the log file:

All the calculations are in parallel for the wave functions.

Thank you in advance.
