FWIW, what did MPICH say for the error?
I followed the install.pdf that comes with mpich. They have you start
up the daemon ring then run mpdtrace. This command tells each daemon
instance to report the hostname. I don't remember the exact error
message, but it was very clear that NODENAME was

I think we could use gai_strerror(3) for this. If we could agree to

rid of SUSv2 and rely on RFC 3493 ;)
It would not be too diff

It would not be too difficult to add gai_strerror() checking into

At this point I decided to give up and try mpich instead. During the

Could a section be added to the FAQ mentioning that the firewall
service should be shutdown over the mpi interface and that the two
-mca switches should be used?
I have added the following line to my .bashrc:
export OMPIFLAGS="-mca oob_tcp_include eth0 -mca btl_tcp_if_include
eth0 --hostfile ~/work/openmpi_hostfile"
and have verified that mpirun $OMPIFLAGS -np 4 hostname works.
Is there a better way of accomplishing this, or is this a matter of

For things like these, I usually use the "dot file" mca parameter
file in my home directory:
http://www.open-mpi.org/faq/?category=tuning#setting-mca-params
That way, I don't accidently forget to set the parameters on a given
run ;).

I have a style question related to this issue that I think is resolved.

I think I fixed the problem. I at least have mpirun ... hostname

The first thing I needed to do was to make the gigabit network an
internal zone in Yast ... firewall (which essentially turns off the
firewall over this interface).
Next I needed to add the -mca options a

Hello,

There can be a whole host of issues with the way you run your
executable and/or the way you have the environment setup. First of
all, when you ssh into the node, does the environment automatically
get updated with correct Open MPI paths? I.e.
Dear Open-MPI list:
I'm trying to run two (soon to be three) dual opteron machines as a
cluster (network of workstations - they each have a disk and OS). I
can ssh between machines with no password. My open-mpi code compiled
fine and works great as an SMP program (using both processors on one
