When I tried to use hydra_nameserver I get the followinf error message
when I launch my application:<br>
<br>

What is wrong<br>
<br>
My application is just a little test program. I have attached it to

Do you have a shared file-system? If yes, you don't need to modify
anything. It should just work. If no, then read below:

following message:
<br>
-nameserver: Nameserver to use for publish/lookup (format is host:port)

<br>
I don't understand what I have to do with this option.
<br>
First I launch the hydra_nameserver . Do I give some options to
<br>
hydra_nameserver ? Do I give some options then, to the two mpiexec to
<br>
launch my two applications?
<br>
</blockquote>
<br>
There are no options required for hydra_nameserver. The two mpiexec's
will need the -nameserver {hostname} option, where {hostname} is the
name of the host where the nameserver is running.
