Hello everyone and excuse my english

I'm trying to run pitzDaily using distributed OpenFOAM, I've set up passwordless communication between the 2 nodes (using rsa), mirror disk sharing the pitzDaily folder (using nfs). However I get the following error after using command:
Code:
mpirun --hostfile machines -np 16 simpleFoam  /home/OpenFOAM/OpenFOAM/run/tutorials/incompressible/simpleFoam/pitzDaily -parallel > log&
Error:
[openfoam2:11635] [[44716,0],0] mca_oob_tcp_recv_handler: invalid message type: 12

My decomPoseParDict is:
Code:
numberOfSubdomains  16;
method          simple;
simpleCoeffs
{
    n           (4 2 2);
    delta       0.001;
}

distributed     yes;

roots
2(
"/home/OpenFOAM/OpenFOAM/run/tutorials/incompressible/mySimpleFoam/pitzDaily" //master node
"/mnt/nfs/pitzDaily" //slave node
	
);
Code:
/home/OpenFOAM/OpenFOAM/run/tutorials/incompressible/mySimpleFoam/pitzDaily
Is the root to the master node's pitzDaily Case

and
Code:
/mnt/nfs/pitzDaily" //slave node
Is the root to the slave node's pitzDaily

Is there something run with my setup ?
