error in MPI_FILE_READ_AT

Post by wuyu »

I'm using the QE6.6 with the EPW5.3.0 to calculate the elph matrix
the program crashed after Bloch2wane. There are similar problems in EPW Forum, but i cannot deal with it.
Here is part of my epwout file.

Band disentanglement is used: nbndsub = 18
Use zone-centred Wigner-Seitz cells
Number of WS vectors for electrons 157
Number of WS vectors for phonons 43
Number of WS vectors for electron-phonon 43
Maximum number of cores for efficient parallelization 387
Results may improve by using use_ws == .TRUE.

Velocity matrix elements calculated
