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
------------------------
