Hi Joao,
Unfortunately, spawn is broken on the development trunk right now. We
are working on a major revamp of the runtime system which should fix
these problems, but it is not ready yet.
Sorry about that :(

Hi all,
I'm getting errors with spawn in the situations:
1) spawn1.c - spawning 2 process on localhost, one by one, the error is:
spawning ...

--
mpirun has exited due to process rank 0 with PID 31390 on
node localhost calling "abort". This will have caused other processes
in the application to be terminated by signals sent by mpirun
(as reported here).
--
With 1 process spawned or with 2 process spawned in one call there is
no output from child.
2) spawn2.c - no response, this init is
MPI_Init_thread (, , MPI_THREAD_MULTIPLE, )
the attachments contains the programs, ompi_info and config.log.
Some suggest ?
thanks a lot.
Joao.
