Abstract: In response to a notification of a fault captured in a system, a fault isolator serially analyzes each clock object to determine captured faults associated with the clock object. For each of the clock objects determined to have a captured fault, the fault isolator initiates a repair action for the chip represented by the clock object. The fault isolator concurrently analyzes the non-clock objects to determine captured faults associated with the non-clock objects after analysis of the clock objects. For each of the non-clock objects determined to have a captured fault, the fault isolator initiates a repair action for the chip represented by the non-clock object.

Abstract: According to one embodiment of the present invention, multiple data scan operations are compacted into a single network message. A plurality of requests to perform a data scan operation on a remote node controller is received, forming a set of received data scan operation requests. A set of data scan operations are generated based on the set of received data scan operation requests, forming a set of generated data scan operations. A network message comprising the set of generated data scan operations is generated, forming a first compacted data scan operation network message. The first compacted data scan operation network message is sent to the remote node controller. A second compacted data scan operation network message is received from the remote node controller, wherein the second compacted data scan operation network message comprises a set of completed data scan operations. The set of completed data scan operations are separated into individual completed data scan operations.
