Hello all,
I have a very strange problem with running OpenFOAM on two computers. The setup might be a bit special, but it should not be a problem. So one instance is a vmware virtual machine (ubuntu) and the second computer is a normal install. All linux and foam versions are the same. The two are connected over a gbit switch. The vmware instance runs with a bridged interface, which gives it an outside DHCP assigned IP. The network itself works fine. I am able to ssh to the other PC and vice versa. I am also able to start a run by e.g. Quote:
mpirun starts up, but it strangely tries to connect to an unknown IP Address!: The vmware machine is the host where I launch the process, 10.132.33.101 is the other machine. Quote:
I started to play with the mpirun parameters, but they did not seem to help e.g.: enforce an interface Quote:
I checked the hosts file on both machines and the ifconfig output. So I am a bit helpless and hope that anybody can figure out the routing problem. I really do not see where he even gets the 10.0.0.2 address from. ![]() Update: i can get rid of the error message by excluding the ip address. Quote:
