Hi all!
I'm getting a error on call MPI_Init_thread and MPI_Comm_spawn.
am I mistaking something?
the attachments contains my ompi_info and source ...
thank!
Joao
....
char *arg[]= {"spawn1", (char *)0};
MPI_Init_thread (&argc, &argv, MPI_THREAD_MULTIPLE, &provided);
MPI_Comm_spawn ("./spawn_slave", arg, 1,
MPI_INFO_NULL, 0, MPI_COMM_SELF, &slave,
MPI_ERRCODES_IGNORE);
.....
and the error:
opal_mutex_lock(): Resource deadlock avoided
