Hi,
I use the following command (mpirun --prefix /usr/local/openmpi1.4.3 -np
4 hello) to successfully execute a simple hello world command on a
single node. Each node has 4 slots. Following the successful execution
on one node, I wish to employ 4 nodes and for this purpose wrote a
hostfile. I submitted my job using the following command:
mpirun --prefix /usr/local/openmpi1.4.3 -np 4 --hostfile hostfile hello
Copied below is the output. How do I go about fixing this issue.

A daemon (pid 22085) 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 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.
