Subject: [OMPI users] How to add nodes while running job
From: Rafael Braga (rafaeltelematica_at_[hidden])

I would like to know how to add nodes during a job execution.
Now my hostfile has the node 10.0.0.23 that is off,
I would start this node during the execution so that the job can use it
When I run the command:

mpirun -np 2 -hostfile /tmp/hosts application

the following message appears:

ssh: connect to host 10.0.0.23 port 22: No route to host
--------------------------------------------------------------------------
A daemon (pid 10773) died unexpectedly with status 255 while attempting
to launch so we are aborting.

There may be more information reported by the environment (see above).

This may be because the daemon was unable to find all the needed shared
libraries on the remote node. You may set your LD_LIBRARY_PATH to have the
location of the shared libraries on the remote nodes and this will
automatically be forwarded to the remote nodes.

mpirun noticed that the job aborted, but has no info as to the process
that caused that situation.

mpirun: clean termination accomplished

thanks a lot,
