Also, is open MPI 1.1 compatible with MPI 1.2.3, I mean to ask is
whether a MPI executable generated using 1.1 is executable by 1.2.3?

i am trying to run a 1.1 generated executable on a remote 1.2.3 host
when i get the following:

amit_at_ubuntu-desktop-1:~/mpi-exec$ mpirun -np 3 --hostfile
/home/amit/junk/mpi-codes/mpi-host-file --mca btl ^openib ./HellMPI

amit_at_debian-desktop-1's password: amit_at_ubuntu-desktop-2's password:
[ubuntu-desktop-1:13202] [0,0,0] ORTE_ERROR_LOG: Data unpack failed in

Note that the host "debian-desktop-1" is 1.2.3 and the other 2 is 1.1
