[Beowulf] ibswinfo, a tool to monitor unmanaged Infiniband switches

[Darren Wise]

Nice one, I own an HP Voltaire 4036 which is managed but am still happy to checkout the github link.

Thanks very much for informing us as I'm sure it will be of huge use to others users, including myself.

Kind regards,
Darren Wise
