(please CC me as I do not receive messages from this list) I trawled a bunch of the SVN history (not all of it!) looking for OpenMPI modifications to ROMIO that I could incorporate into upstream MPICH-ROMIO.
I have pushed a handful of changes to the 'romio_sync_from_ompi' branch of http://git.mpich.org/mpich-dev.git Could I humbly request a look-see from y'all? My main goal was to find dropped patches like Edgar Gabriel's "can't switch on datatype" patch. There don't seem to be any. But my second goal was to make life easier for you: if pulling in these changes complicates your life, let me know and I'll drop any/all of them. Thanks ==rob
