Hi,
FCoE is for storage, Ethernet is for the network.
I assume you can ssh into your nodes, which means you have a TCP/IP, and
it is up and running.
i do not know the details of Cisco hardware, but you might be able to
use usnic (native btl or via libfabric) instead of the plain TCP/IP network.
at first, you can build Open MPI, and run a job on two nodes with one
task per node.
in your script, you can
mpirun --mca btl_base_verbose 100 --mca pml_base_verbose 100 ...
this will tell you which network is used.
Cheers,
Gilles

Hola,
I'm new to MPI and OpenMPI. Relatively new to HPC as well.
I've just installed a SLURM cluster and added OpenMPI for the users to
take advantage of.
I'm just discovering that I have missed a vital part - the networking.
I'm looking over the networking options and from what I can tell we
only have (at the moment) Fibre Channel over Ethernet (FCoE).
Is this a network technology that's supported by OpenMPI?
(system is running Centos 7, on Cisco M Series hardware)
Please excuse me if I have terms wrong or am missing knowledge. Am new
to this.
cheers
Lachlan
