Subject: [OMPI users] How to use Multiple links with OpenMPI? ?????????????????

Hi everyone, I want to ask how to use multiple links (multiple NICs) with OpenMPI. For example, how can I assign a link to each process, if there are 4 links and 4 processors on each node in our cluster? Is this a correct way? hostfile: ---------------------- host1-eth0 slots=1 host1-eth1 slots=1 host1-eth2 slots=1 host1-eth3 slots=1 host2-eth0 slots=1 host2-eth1 slots=1 host2-eth2 slots=1 host2-eth3 slots=1 ... ... ... ... host16-eth0 slots=1 host16-eth1 slots=1 host16-eth2 slots=1 host16-eth3 slots=1 ------------------------
