I just commited the very last modifications of ROMIO (mpich2-1.3rc1)
into bitbucket.

Sweet!
The work in this repo consisted in refreshing ROMIO to a newer
version: the one from the very last MPICH2 release (mpich2-1.3b1).
Great! I saw there was another MPICH2 release, and I saw a ROMIO patch or
three go by on the MPICH list recently. Do you expect there to be major
differences between what you have and those changes?
I don't have any parallel filesystems to test with, but if someone else in the
community could confirm/verify at least one or two of the parallel filesystems
supported in ROMIO, I think we should bring this stuff into the trunk soon.
Testing:
1. runs fine except one minor error (see the explanation below) on various FS.
2. runs fine with Lustre, but:
. had to add a small patch in romio/adio/ad_lustre_open.c
Did this patch get pushed upstream?
======== The minor error ===================
The test error.c fails because OpenMPI does not handle correctly the
"two level" error functions of ROMIO:
error_code = MPIO_Err_create_code(MPI_SUCCESS, MPIR_ERR_RECOVERABLE,
myname, __LINE__, MPI_ERR_ARG,
"**iobaddisp", 0);
OpenMPI limits its view to MPI_ERR_ARG, but the real error is "**iobaddisp".
Do you mean that we should be returning an error string "**iobaddisp" instead of
"MPI_ERR_ARG"?
