Interoperability
QLogic OFED+ participates in the standard IB subnet management protocols for
configuration and monitoring. Note that:
QLogic OFED+ (including Internet Protocol over InfiniBand
®
(IPoIB)) is
interoperable with other vendors’ InfiniBand
®
adapters running compatible
OFED releases.
In addition to supporting running MPI over verbs, QLogic provides a
high-performance InfiniBand
®
-Compliant vendor-specific protocol, known as
PSM. MPIs run over PSM will not interoperate with other adapters.
