Modern High Performance Computing Systems have grown in size to thousands of nodes, having tens of thousands of processors and thousands of disks, which has resulted in an increase in the rate of failures. Fault Management in such systems has been traditionally handled by individual components at different levels in the stack, with no coordination among different components in the system. As a result, different components cannot benefit from the knowledge of the failures experienced by others. The CiFTS initiative aims to provide a coordinated infrastructure that will enable Fault Tolerance Systems to adapt to faults occurring in the operating environment in a holistic manner.

The Fault Tolerance Backplane provides a common infrastructure for the Operating System, Middleware, Libraries and Applications to exchange information related to hardware and software failure in real time. Fault-aware components can subscribe to be notified about one or more events of interest from other components, and notify other components about the faults it comes across.

The FTB-IB component uses the FTB Infrastructure to notify other FTB enabled components about failures in the InfiniBand network. The FTB-IB component uses the Asynchronous Event Handler provided by the IB Verbs library that is part of the OFED Software. Applications that require notification about one or more of these events can use the FTB infrastructure to subscribe to them.
