I am having problems to run a simulation using qsub.

It works ok not using qsub:
Using mpirun --hostfile machines -np 504 simpleFoam -parallel > log &

But using:
qsub -cwd lanza.sh

With lanza.sh:
#$ -j y
#$ -S /bin/bash
#$ -pe ompi 504
#$ -q lenovo.q
#$ -m be
#$ -M mail@mail.com
. /opt/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc


echo "Start"
mpirun -np 504 simpleFoam -parallel
echo "End Parallel Run"

I obtain these files and the run does not progress:
lanza.sh.po38

-catch_rsh /opt/sge/default/spool/nodo01/active_jobs/38.1/pe_hostfile
nodo01

A daemon (pid 8509) 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.

End Parallel Run

Any idea ab

can you login into all nodes using ssh without giving a password?
