Okay, let's start with the basics :-)

Looks to me lik
Looks to me like your 65th host is missing the dstore library - is it possible
you don't have your paths set correctly on all hosts in your hostfile?

Hi all,
Trying to run OpenMPI ( trunk Revision: 32428 ) I faced the problem running
OMPI with more than 65 procs.
It looks like MPI failes to open 66th connection even with running `hostname`
over tcp.
It also seems to unrelated to specific host.
All hosts are Ubuntu 12.04.1 LTS
mpirun -np 66 -
