The problem is in your cmd line:
mpirun --np 2 --nolocal APPNAME
You forgot to include a -hostfile or -host option, so OMPI only knows
about your local node - which you told it not to use.
Provide a hostfile, or specify a set of hosts with -host, and it
should work fine.

Hello all,
I am sorry to ask what is probably a newbie question, I have
searched the archives but am probably not using the proper key word
to locate.
I am working on an atmospheric model which uses openmpi/openrte. I
have two nodes setup but the model only runs on one node.
I can use mpirun to execute an application on another node by
entering the below on HOST1:
mpirun --np 2 --host HOST2 APPNAME
In this scenario, the system connects via ssh to HOST2 and runs the
application without a problem.
If I attempt to run:
mpirun --np 2 --nolocal APPNAME
I get:

Looking at the source code, that is the area where the available
nodes are enumerated and this error appears to indicate no "non-
local" node is available if I am interpreting this correctly.
I have the hosts file correct along with the ssh key so the user can
login without a password etc etc. I don't know where the system
looks for identification of node IPs so this can be enumerated.
Can someone give me a quick pointer to the correct location in the
manual (I realize the answer is RTM but I have not found the answer
in the manual thus far so I figured I would throw it out there to
the experts).
Thanks for your patience with my query.
