Subject: [OMPI users] Error connecting to nodes ?
From: Ashika Umanga Umagiliya (aumanga_at_[hidden])

Greetings all,

In my MPI environment I have 3 Debian machines all setup openMPI in
/usr/local/openMPI,
configured PATH and LD_LIBRARY_PATH correctly.
And I have also configured passwordless SSH login in each node.

But when I execute my application , it gives following error , what
seems to be the problem ?

Thanks in advance.

A daemon (pid 7210) died unexpectedly with status 127 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 was unable to cleanly terminate the daemons on the nodes shown
below. Additional manual cleanup may be required - please refer to
the "orte-clean" tool for assistance.
