fine.
I am wondering what changed from OMPI 1.2.x to OMPI 1.4.x that prevents
expected behavior, and is it possible to get it from OMPI 1.4.x by, say,
tuning some parameters?

The example in my initial email was deliberately simplified to

I should have read your original note more closely and I would have spotted the

Do I have to rebuild all the applications with Open MPI 1.3?
Is there a better way to do a smooth upgrade?
Thank you.

Hello,
We have a number of applications built with Open MPI 1.2 in a shared
multi-user environment. The Open MPI library upgrade has been always
transparent and painless within the v1.2 branch. Now we would like

some successful tests done.
Is it safe to run an application built with 1.3.x under 1.2.x? Does it
make sense to you?
