It is quite likely that you have IPoIB on your system. In that
case, the
TCP BTL will pickup that interface and use it.
If you have a specific interface you want to use, try -mca
btl_tcp_if_include eth0 (or whatever that interface is). This tell
the TCP
BTL to only use the specified interface, so it will either fail
(if that
interface isn't available or doesn't exist) or use only that one.
no, I don't have IPoIB configured. I tried anyway your suggestion
and I
got the same results as before. The weird thing is that even if use
-mca btl_tcp_if_include eth2
where eth2 doesn't exist I get the same results...
Thanks, Daniel.
