I forwarded this on to the ROMIO maintainers; let's see what they say...

here is a patch that we use on our development version to silence
that warning, you have to apply it to.
ompi/ompi/mca/io/romio/romio/mpi-io/io_romio_close.c
I would not like to commit that to the repository since I can not
oversee whether it causes problems in some other settings/scenario/
file systems. However, it fixed for us the problems when
experimenting with shared file pointers (e.g.
MPI_File_write_ordered) and did not create any issues so far.
Application of that patch at your own risk:-)
Thanks

Hi,
Sorry about my previous message, it was sent before I'd finished
composing it.
Whenever I use MPI_File_write_ordered(), all but one process send
the following message to stderr.
ADIOI_GEN_DELETE (line 22): **io No such file or directory
I have read
http://www.open-mpi.org/community/lists/users/2008/01/4936.php
which suggests that this message appears because my program is
trying to delete a file that does not exist, but my program does
not explicitly delete any files. I've included a test program to
demonstrate the message.
Is there anything I can do to avoid or suppress this message?
The message I referred to before says that I could "ignore errors
from MPI_File_delete". How do I do that?
Thanks,
Brian
