Today I compile the PEO module on Linux Debian 7.5 64bits
with MPICH2 1.4 and gcc(4.7.2).  I use hydra that is the defaut process manager.

 

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:

PMPI_Allgather(958) : MPI_Allgather(sbuf=0x7fff8a8f7de8,
scount=128, 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

 and the schema.xml file is configure as:
<schema>   <group scheduler="0">                  <node name="0" num_workers="0">                  </node>                  <node name="1" num_workers="0">                  <runner>1</runner>                  </node>   </group></schema>


 

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.
