Re: Infiniband over slurm

The problem is when I check the IB traffic with "watch ifconfig ib0" I get:

Every 2,0s: ifconfig ib0                                                         Tue Jan  9 10:35:09 2018

Infiniband hardware address can be incorrect! Please read BUGS section in ifconfig(8).
ib0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 2044

This is while running... And when I check my Ethernet connection I cant see traffic going back and forward when the tests runs, and stops when it finishes... Giving me the idea that is in fact the Ethernet connection the one being used
