Hi Ralph,
Thanks a lot for your effort and giving us freedom to choose hosts
dynamically. I am really excited to see such great feature working in my
programs.
again thank you very much :)

Hi Vipin
I have added support for these features to the OMPI trunk repository.
They are only accessible via MPI_Comm_spawn or
MPI_Comm_spawn_multiple, specified as MPI Info keys "add-host" and
"add-hostfile". Check the man pages for those functions to see how
they are used.

Hi Ralph,
To add few more points to my queries, as you said earlier "addhost" and
"addhostfile" features will come soon. So can you please tell how we are
going to use those features, will there be any API for that to calll from
inside the program or we have to execute command to use those featur
Hi Ralph,
I am thankful to your reply regarding the matter, however to carry forward
with my activities it would be of great help if I can know where
OpenMpi/mpirun holds the contents of "hostfile" so that I can dynamically
add/alter the values till such a feature is officially included in OpenMpi
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- as
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
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 "" as its
value but but I am getting the error
