Consider following hostfile (used with lamboot)

#hostfile for lamboot
sparc7.cs.iit.edu
sparc8.cs.iit.edu
sparc9.cs.iit.edu

Consider following MPI_Info object which contains only one key

MPI_Info_create(&info);
MPI_Info_set(info, "lam_spawn_sched_round_robin", "n1");

(Ref: http://www.lam-mpi.org/MailArchives/lam/msg02641.php)

And I spawn only one process using this info object like this

MPI_Comm_spawn("./test_tree", param, 1,
             info, 0, MPI_COMM_SELF, &everyone,
             MPI_ERRCODES_IGNORE);

1. On which machine/host/node is the process spawned if i run the program
from sparc7 (i.e. first machine in the hostfile)

2. From sparc8 (second machine in the hostfile)

3. And from sparc9 (third machine)

I believe in all three cases new process will always be spawned on n1, which
corresponds to sparc8.cs.iit.edu.

Is my understanding correct?

Thanks

Rohan Inamdar.
