Hey, sorry, I don't check in here very often, but I'm the "ROMIO guy"
around these parts. This is a harmless warning message.

You see this with more than one process because one process "won" and
deleted the file, and the other N-1 processes then try to delete a
file that doesn't exist.

If you ignore errors from MPI_File_delete, then you won't see this
error :>

MPI_FILE_DELETE is not a collective operation, so you can also just call
this from one process.
