[mpich-discuss] Problems with mpi spawn multiple

[Rajeev Thakur]

You can't pass MPI::ROOT to Spawn_multiple. You have to give the rank of the
process in COMM_WORLD that is the root.

Hello,

I have problems when i try use spwan multiple in mpich2 (1.0.7 version)

I receive this error when i execute my code:

[0]Fatal error in MPI_Comm_spawn_multiple: Other MPI error, error stack:
[0]MPI_Comm_spawn_multiple(152)..: MPI_Comm_spawn_multiple(count=2,
cmds=0x816b080, argvs=(nil), maxprocs=0x816afc0, infos=0x81a1600, root=-3,
MPI_COMM_WORLD, intercomm=0xbfa96f24, errors=(nil)) failed

my code when I supose have a problem:

universe_size = 3;

  for (int i = 0; i < universe_size-1; i++){
    strcpy(program_name[i], "worker_02"); 
    information[i] = information[i].Create();
    information[i].Set("wdir","/home/fernando_luz/");
 
information[i].Set("path","/home/fernando_luz/SVN/TPN3/casos_testes/02/worke
r_02/");
    information[i].Set("host","10.2.7.53");
    n_proc[i] = 1;
  }
  everyone = MPI::COMM_WORLD.Spawn_multiple(universe_size-1, (const char**)
program_name, MPI::ARGVS_NULL, n_proc, information, MPI::ROOT);
anybody have ideas?

Thanks 

Fernando Luz
