That is a good sign, it means orted was started on both nodes
strictly speaking, you should confirm both nodes appear 16 times each in
the output,
do you can draw any firm conclusion

You will see those warning the first time you connect to a new host.
If it printed the hostname from each processor, it should be OK.

I wrote 2 new node names(which I had not used before) in "myhostfile".
And when I run it from login terminal, it says:

Sorry, but I can't get it.
Would you please provide a demo_code(in context of the working code) ?
Thanks.

Jeff, Gilles
Here's my scenario again when I tried something different:
I've interactively booked 2 nodes(cx1015 and cx1016) and working in
"cx1015" node.
Here I hit "module load openmpi" and "module load nwchem"( but I don't know
how to "module load" on other node).
Using the openmpi command to r
The initial error was ompi could not find orted on the second node, and
that was fixed by using the full path for mpirun
if you run under pbs, you should not need the hostile option.
just ask pbs to allocate 2 nodes and everything should run smoothly.
at first, I recommend you run a non MPI appli

You are having two problems:
1. In the first "orted not found" problem, Open MPI was not finding its "orted"
helper executable on the remote nodes in your cluster. When you "module load
..." something, it just loads the relevant PATH / LD_LIBRARY_PATH / etc. on the
local node; it d
I'm on a HPC cluster. So, the openmpi-1.6.4 here installed as a module.
In .pbs script, before executing my code-line, I'm loading both "nwchem"
and "openmpi" module.
It is working very nicely when I work on single node(with 16 processors).
But if I try to switch in multiple nodes with "hostfile" o
HI,
I have tried using full paths for both of them. But stuck in the same issue.

Is ompi installed on the other node and at the same location ?
did you configure ompi with --enable-mpirun-prefix-by-default ?
(note that should not be necessary if you invoke mpirun with full path )
you can also try
/.../bin/mpirun --mca plm_base_verbose 100 ...
and see if there is something wro
Yes, I have tried this and got following error:
*mpirun was unable to launch the specified application as it could not find
an executable:*
*Executable: nwchem*
*Node: cx934*

Given that: I have to run my code with "nwchem filename.nw" command.

Can you try running invoking mpirun with its full path instead ?
e.g. /usr/local/bin/mpirun instead of mpirun

Here is the other details,
a. The Openmpi version is 1.6.4
b. The error as being generated is :
*Warning: Permanently added 'cx0937,10.1.4.1' (RSA) to the list of known

Would you please tell us:
(a) what version of OMPI you are using
(b) what error message you are getting when the job terminates
