r, if I try to reproduce your experiment then I get the exact
same result as you do.

launch so we are aborting.

I should have read your original note more closely and I would have spotted the
issue. How a hostfile is used changed between OMPI 1.2 and the 1.3 (and above)
releases per user requests. It was actually the SGE s
the process distribution is predetermined -- one less worry for
users playing with mpirun options.
The example in my initial email was deliberately simplified to
demonstrate the problem.

Max slots: 0
The content of the 'hosts' file:
node01 slots=1
node02 slots=1
node03 slots=1
node04 slots=1

Hi,
OpenMPI integrates with Sun Grid Engine really well, and one does not
need to specify any parameters for the mp
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?

system-wide upgrade. It's worth trying.

Remember also that the RTE API's changed between 1.2 and 1.3 - so I'm
not sure what will happen in that case. It could be that the ones
touching the MPI layer remained stable (don't honestly r

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?

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

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.
