Can you send the full output of "ifconfig" (or "ip addr") from one of your 
compute nodes?

Subject: [OMPI users] Multiple IPs on network interface

Hi,

I am aware that section 13 in the FAQ says that MPI "in general" wont work with 
a network interface that has two IPs. However, I've had slurm running python 
and C programs on a cluster of 21 nodes for a while and haven't had any issues 
until I tried running some OSU micro benchmarks. This resulted in this 
error<https://pastebin.com/uY9TJF9x> , i'm not entirely sure why each node has 
two IPs, i believe it is related to netbooting as they are all netbooted.

This is the slurm script<https://pastebin.com/vn8nbSxQ> I'm using to start the 
job. The -mca section I added to fix the problem however doesn't do anything as 
both the ips are on the eth0 interface.

Is there anything I can do to run these benchmarks?

Let me know what other details I need to provide as I'm not sure where to start.

Thanks,

George Johnson
