Subject: [OMPI users] ORTE_ERROR_LOG

Hi

I am trying to setup a simple two machines home cluster. Later I may increase the number to 4 machines.

I have a bridged modem so each of my machines has its own ip.

My target is now to calculate a simple OpenFOAM tutorial with two computers and together with 14 cores.

However when I run:

mpirun /opt/openmpi-1.6.5/bin/mpirun -hostfile /home/tommi2/Desktop/machinefile -np 14 icofoam cavity -parallel

 I get this kind of error:

[caelinux:31859] [[43391,1],0] ORTE_ERROR_LOG: A message is attempting to be sent to a process whose contact information is unknown in file rml_oob_send.c at line 104
[caelinux:31859] [[43391,1],0] could not get route to [[INVALID],INVALID]
[caelinux:31859] [[43391,1],0] ORTE_ERROR_LOG: A message is attempting to be sent to a process whose contact information is unknown in file base/plm_base_proxy.c at line 81

Please tell me what to do in order to fix this and thanks in advance. The reason is probably simple cos I am a Linux newbie.
