Hi everyone I'm a new Open MPI user and I have just installed Open MPI in
a 6 nodes cluster with Scientific Linux. When I execute it in local it
works perfectly, but when I try to execute it on the remote nodes with the
--host option it hangs and gives no message. I think that the problem
could be
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

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:
[itanium1] /home/otro > mpirun --mca plm_base_verbose 30 --host itanium2

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.
