Pelegant Error: Unable to read ascii file with SDDS_MPI

Post by Hwang, Ji-Gwang » 25 Jan 2023, 10:37

Dear Michael,

I am trying to do a simulation using Pelegant with particle coordinates defined by a sdds file (ASCII format).
But it shows the error message "Unable to read ASCII file with SDDS_MPI" when the code is checking the sdds file.
Since the file is working well with single-core elegant runs, it would not be an issue for the sdds file.
Do you have any idea about this issue?

Best regards

Ji-Gwang Hwang

Ji-Gwang,

The problem is that Pelegant can't read ASCII files using parallel I/O. Just convert the files to binary form:

Code: Select all

sddsconvert -binary <filename>
