Hi there.
I'm developing a distributed system with a communication layer based on Open
MPI. As part of my project, I have to create a process scheduler. So I
decided to use the MPI_Spawn function to dynamically create (it is an
requirement of the system) the process across the cluster's nodes.

Hi,
I think I was not specific enough. I need to spawn the copies of a process
in a unique mpi_spawn call. It is, I have to specify a list of machines and
how many copies of the process will be spawned on each one. Is it possible?
I would be something like that:
machines #copies
m1
I believe I answered that question. You can use the hostfile info key, or you
can use the host info key - either one will do what you require.

Ralph,
I have the same issue and I've been searching how to do this, but I couldn't
find.
What exactly must be the string in the host info key to do what Rodrigo
described?

value
<<< consisting of a string "host1,host2,ho
You need to use MPI_Comm_spawn_multiple. Despite the name, it results in a
single communicator being created by a single launch - it just allows you to
specify multiple applications to run.
In this case, we use the same app, but give each element a different "host"
info key to get the behavior
Ralph, thank you the reply.
I just try what you said and it works! I didn't think to try the array of
info arguments because in the spawn_multiple documentation I read the
follow:
"... *array_of_info*, is an array of *info *arguments; however, *only the
first argument in that array is used. Any s
Thanks for pointing this out - it's an error in our man page. I've
fixed it on our devel trunk and will get it push'd to the release.

Hi Thatyene and Ralph.
Now I got the solution and it worked fine. I did not try spawn_multiple
because I've read the same documentation
Thanks so much!
