Abstract
Methods, apparatus, and systems for reliable replication mechanisms based on active-passive HFI protocols build on top of non-reliable multicast fabric implementations. Under a first hardware-based scheme, a reliable replication mechanism is (primarily) implemented via Host Fabric Interfaces (HFIs) coupled to (or integrated in) nodes coupled to a non-reliable fabric. Under this approach, the HFIs take an active role in ensuring reliable delivery of multicast messages to each of multiple target nodes. Under a second hybrid software/hardware scheme, software running on nodes is responsible for determining whether target nodes have confirmed delivery of multicast messages and sending retry messages for cases in which delivery is not acknowledged within a timeout period. At the same time, the HFIs on the target nodes are responsible for generating reply messages containing acknowledgements rather than software running on the target nodes.
