Add message for filesize in csds
As the CSDS over allocate the file size, we need a way to know the actual file size used.
Currently, I am doing a MPI communication in between each step just to print this information. I am not sure what is the best approach:
- Output every N steps
- Doing the MPI communication only if required (but I am not sure how to get the verbosity level on nodes != 0)
- Fine like this as it should not be a significant amount of time
- Adding it to
engine_collect_end_step
- Something else?
