IB vs Omnipath

Hi,
Here in Marseille, we are in the process of buying a new general-purpose (ie not Molcas-only) cluster. When Molcas is run in parallel mode over several nodes, we usually rely on InfiniBand to speed up inter-node communications. However, Intel quite recently introduced their own solution, Omnipath. Has everyone here already tried it? If so, what about its performances wrt IB (Mellanox or QLogic)? Of course, I'd appreciate feedback for Molcas jobs!
