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
        inet  netmask  broadcast
        inet6 fe80::221:2800:1a0:f831  prefixlen 64  scopeid 0x20<link>

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
