Do you use any of the other ROMIO file system drivers? If you don't

What if you use a driver and it's not on the list? First off, let me
know and I will probably want to visit your site and take a picture of
your system.
:-), but what about plfs, which seems a notable omission? The patches
in the plfs distribution don't apply to recent adio, at least the
version in ompi 1.8 as far as I remember. I wonder if there's any
chance of fixing that and including it, assuming it's still worthwhile
with Lustre in particular.
We didn't need to deploy PLFS at Argonne: GPFS handled writing N-to-1
files just fine (once you line up the block sizes), so I'm beholden to
PLFS communities for ROMIO support.
It wouldn't hurt for me to bug them once again about getting that into
mainline ROMIO. Perhaps we both think the ball is in the other's court.
