I am trying to build a cluster with 2 nodes each
being a dual processor xeon machine. I have installed
openMPI on one of the machines in /opt/open-mpi folder
and have kept the folder shared across the network
thru nfs mounted again in the same folder.
Now I would like to run mpi code involving both
machines. I run the code with command
mpirun --hostfile hostfile -np 2 a.out
where hostfile has ipaddresses of both the
machines(192.168.1.1(master node) and
192.168.1.2(slave node)).
I get the error
----------
orte: command not found
ERROR : A daemon on node 192.166.1.2 failed to start
as expected
ERROR : there may be more information available from
the remote shell (see above)
ERROR : the daemon exited unexpectedly with status

Could you please let me know how to get over this
problem?
This usually means that on the remote node, /opt/open-mpi/bin is not
in your path. We have an FAQ item on this issue:
http://www.open-mpi.org/faq/?category=running#adding-ompi-to-path
If this doesn't solve your problem, please let us know.
