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.
