Josh,
i started updating ROMIO some times ago (the latest version was 3.2b1 at
that time).
iirc, ROMIO 3.2 introduced some asynchronous operations that involve
MPI_Grequest.
i cannot remember what i did for that (e.g. #ifdef out ? compile but no
test ?).
today, the stable version is 3.2, and the preview version is 3.3a2.
anyway, i finally gave up on that, mainly because of an apparent lack of
interest from our fellow developers.
(at that time, the focus was on making ompio production ready)
the port is still available in my github repo at
https://github.com/ggouaillardet/ompi/tree/refresh/romio32b1
and this is something i can resume when needed (we just have to agree on
romio version 3.2 vs 3.3a2).
if you are going to SC, i'll spend quite some time at the RIST booth
#219 and i will be happy to discuss
this face to face.
Cheers,
Gilles

We (IBM) are interested in maintaining support for ROMIO in Open MPI.
We are investigating upgrading the ROMIO version inside Open MPI, but
I have no ETA on when that work will be complete/available.

Farouk,
as far as i am concerned, there is no plan to stop supporting ROMIO.
that being said, i am not aware there are any plans to upgrade to the
latest ROMIO in a near future.
Also, please note ROMIO is the default module when the Lustre
filesystem is used.
Cheers,
Gilles
