[mvapich-discuss] no route to host

[Hoot Thompson]

I'm trying to run a simple test (osu_benchmark) over a 10GigE interface
and for some reason it's trying to use eth0 (192.x addresses) whereas
the intended host addresses are 10.10.10. and 10.10.10.2 (resolved
in /etc/hosts). A simple mpirun test works as expected. Is there a
configuration I'm missing?

Thanks in advance,

Hoot
