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
