At the moment, the answer is "no". :-/
However, we do have a "ticket" in our plans to add a "addhost" and
"addhostfile" capability to the system. I haven't implemented it yet
because of other priorities and the fact that nobody has asked for it
before now.
Well...actually, people -did- ask for it a long time ago, but not for
quite awhile now. ;-)
Anyway, I can implement those features pretty easily. Could get to it
in the next few days - otherwise, it will have to wait another week as
I will be out.
Either way, though, it would only be in the OMPI devel trunk until the
next feature series (1.5) has its first release. Haven't set the date
for that, though it will likely be this summer.

Hi all,
I got the solution but its not flexible. I have to provide two host
files "chfile" and "dhfile". Contents of host files are as follows
$ cat chfile
#This file contains all slaves as well as master node
localhost
200.40.70.193
$cat dhfile
#This file contains all slave nodes
200.40.70.193
and the command line I am using is
$ mpirun -np 1 -hostfile chfile launcher -hostfile dhfile
but this is not what I want.
I don't know in advance which and how many remote nodes can be
there. Dynamically nodes may be added and requested to serve the
master. So I am assuming that I have only local machine where I will
invoke launcher program. When one remote node gets added launcher
program will launch one "slave" in local machine and one "rslave" in
remote machine.
Is there any other way to do this.
Thanks.

Hi all,
I am trying to spawn dynamically processes in remote as well as
local machine using MPI::Intracomm::Spawn_multiple. I am using
MPI::Info object to tell where to launch processes using "host" key
and "<ip_address>" as its value but but I am getting the error
--------------------------------------------------------------------------
There are no allocated resources for the application
slaveprocess
that match the requested mapping:
Verify that you have mapped the allocated resources properly using the
--host or --hostfile specification.
--------------------------------------------------------------------------
I tried with "<hostname>" too.
but its not working.
It works fine if I give the value "localhost" to "host:" key. It
launches successfully processes in local machine.
any help will be greatly appreciated.
