Hi All,
I just checked the recent nightly MTT results and found two things of note,
one for the MTT community, the other for the OMPI developers.

For both, see http://www.open-mpi.org/mtt/reporter.php?do_redir=143
for details of the failed MTT tests with the OMPI trunk at r14180.

1) For MTT developers:
The MTT intel test suite is incorrectly seeing a failed MPI_Allgatherv_f
test as passed, yet is correctly detecting that the MPI_Allgatherv_c
test is failing.
The STDOUT from "passed" MPI_Allgatherv_f seems to indicate that the tests
actually failed in a similar way to the _c version, but MTT thinks it passed.
I've not had time to diagnose why MTT is missing this... anyone else have
some spare cycles to look at this?

2) For OMPI developers:
The MPI_Allgatherv_* tests are failing as of r14180 in all test conditions
on the IU machines, and others, yet this passed the night before on r14172.

Looking at the svn log for r#'s r14173 thru r14180, I can narrow it down to
one of these changes as the culprit:
https://svn.open-mpi.org/trac/ompi/changeset/14180
https://svn.open-mpi.org/trac/ompi/changeset/14179
https://svn.open-mpi.org/trac/ompi/changeset/14174 (Not likely)

My money is on the much larger r14180 changeset.
The other r#'s aren't culprits for obvious reasons.
