Today I compile the PEO module on Linux Debian 7.5 64bits with MPICH2 1.4
and gcc(4.7.2).

I have the problem when I try to run the Lesson5 (island model). I have two
desktop connected to the hub and properly set up ssh, but when i try to run
the example with, mpiexec -f hosts -n 1 ./island @param : -n 1 -wdir
/home/usuario/ParadisEO-2.0/build/peo/tutorial/Lesson5 ./island @param , I
get the next mistake:

Fatal error in PMPI_Allgather: Invalid buffer pointer, error stack:
PMPI_Allgather(958) : MPI_Allgather(sbuf=0x7fffbebe5488. scount=128,
MPI_CHAR, rbuf=0x7fffbebe5488, rcount=128, MPI_CHAR, MPI_COMM_WORLD) failed
PMPI_Allgather(931): Buffers  must not be aliased
Fatal error in PMPI_Allgather: Invalid buffer pointer, error stack:

MPI_CHAR, rbuf=0x7fff8a8f7de8, rcount=128, MPI_CHAR, MPI_COMM_WORLD) failed
PMPI_Allgather(931): Buffers  must not be aliased


where the hosts file is the machine file maps hosts to processes and
contains the following:

PCmaestro
PCesclavo0


Can anyone help me, please? and Can anyone explain the aim of the
schema.xml file?, Thank you very much.

Si me pudieran responder en español estaría muy agradecido, saludos.
