I'm afraid I have no expereince with SELinux -- I don't know what it restricts.
Generally, you need to be able to run processe
trying to open some tcp sockets back).
Can you open random tcp sockets between your nodes? (E.g., in non-mpi
processes)

I've been checking the /var/log/messages on the compute node and there is
nothing new after executing ' mpirun --host itanium2 -np 2
helloworld.out',
but in the /var/log/messages file on the remote node it appears the
following messages, nothing about unix_chkpwd.

I changed the SELinux config to permissive (log only), and it didn't
change anything. Back to the drawing board.

I've been having similar problems using Fedora core 9. I believe the
issue may be with SELinux, but this is just an educated guess. In my
setup, shortly after a login via mpi, there is a notation in the
/var/log/messages on the compute node as follows:
Mar 30 12:39:45 kernel: type=1400 audi
Looks to me like you have an error in your cmd line - you aren't specifying the
number of procs to run. My guess is that the system is hanging trying to
resolve the process map as a result. Try adding "-np 1" to the cmd line.
The output indicates it is dropping slurm because it doesn't see a slu
I've benn investigating and there is no firewall that could stop TCP
traffic in the cluster. With the option --mca plm_base_verbose 30 I get
the following output:

Did you configure OMPI with --enable-debug? You should do this so that more
diagnostic output is available.
You can also add the following to your cmd line to get more info:
--debug --debug-daemons --leave-session-attached
Something is likely blocking proper launch of the daemons and processes
The processes are running on the remote nodes but they don't give the
response to the origin node. I don't know why.
With the option --mca btl_base_verbose 30, I have the same problems and it
doesn't show any message.
Thanks
