Subject: [OMPI users] use additional interface for openmpi
From: worldeb_at_[hidden]

 Hi folks,

I want to use for openmpi communication the additional ethernet interfaces on node and head node.
its is eth1 on nodes and eth4 on head node.
So how can I configure openmpi?

If I add in config file
btl_base_include=tcp,sm,self.
btl_tcp_if_include=eth1

will it work or not?

And how is it working with torque batch system (daemons listen eth0 on all nodes).

Thanx.
