Hi Pavan,<br>
<br>
I can run my application on system with a shared file-system, but also
on system without shared file-system.<br>
<br>
The usage is to perform coupling between parallel programs with more
than 1 process.<br>
<br>
My test program uses the same executable, but it can be different
executables.<br>

You didn't answer my first question. Can you please let us know about

With respect to the test program, what's the exact usage? It looks like
it needs to be run with more than 1 process. You mentioned that there
are two applications? Are both using the same executable (with
different input arguments)?

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:

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

hydra_nameserver ? Do I give some options then, to the two mpiexec to

launch my two applications?

<br>
There are no options required for hydra_nameserver. The two mpiexec's
<br>
will need the -nameserver {hostname} option, where {hostname} is the
<br>
name of the host where the nameserver is running.
