I need to make that error string be google-able -- I'll add it to the
faq. :-)
The problem is likely that you have multiple IP addresses, some of
which are not routable to each other (but fail OMPI's routability
assumptions). Check out these FAQ entries:
http://www.open-mpi.org/faq/?category=tcp#tcp-routability
http://www.open-mpi.org/faq/?category=tcp#tcp-selection
Does this help?

I have migrated from LAM/MPI to OpenMPI. I am not able to
execute simple mpi code in which master sends an integer to slave.
If i execute code on single machine i.e start 2 instance on same
machine (mpirun -np 2 hello) this works fine.
If i execute in cluster using mpirun --prefix /usr /local -
np 2 --host 199.63.34.154,199.63.34.36 hello
it gives following error "btl_tcp_endpoint.c:
572:mca_btl_tcp_endpoint_complete_connect] connect() failed with
errno=113"
I am using openmpi-1.2
