Hi,

Can I configure Clemson cluster nodes to use Infiniband transport instead of Ethernet? How can I do that?

Currently, I have r6525 nodes reserved. I am trying to configure those to use Infiniband instead of Ethernet. I have changed the device configuration of the experimental CX-6 NIC to use Infiniband but it isn't working.

Thank you.

Kind regards,
Ashfaq

Those nodes are connected to Ethernet-only switches, so Infiniband is not
possible as I understand it.
