error in MPI_FILE_OPEN

Post by plasmon »

Dear developers,

Recently we met a problem when using EPW5.3 on the electron-phonon matrix data calculated by EPW5.0. The error message is listed as follows, and I have attached the epw.in here. Could you please tell me how to fix this problem? Thank you very much!

Best regards,
Hao Zhang

Dear plasmon:

Probably, the following change in EPW v5.3 might be the cause of your error.

Excerpt from https://docs.epw-code.org/doc/Releases.html
Change in the file name of prefix.epmatwp (prefix.epmatwp1 changed into prefix.epmatwp)
In addition, I don't know about EPW v5.0, but there might be additional differences between EPW v5.3 and EPW v5.0; some of them might lead to the problem even though they wouldn't lead to the run-time error.
I would suggest you to at least look at the history of all changes, in particular incompatible ones, listed at https://docs.epw-code.org/doc/Releases.html .

Sincerely,

H. Lee
