    摘要: A processor includes a plurality of processing sections, each of which executes a predetermined process. A plurality of fault detecting circuits are respectively provided for the plurality of processing sections, to detect a fault in one of the plurality of processing sections as a fault processing section to generate a fault detection signal. A fault monitoring and control section controls a normal processing section as at least one of the plurality of processing sections other than the fault processing section to execute a relieving process in response to the fault detection signal. The relieving process is determined based on a process load of the fault processing section, a process load of the normal processing section, and priority levels of processes to be executed by the fault processing section and the normal processing section.

    摘要: The present application is directed to systems and methods for providing failover connection mirroring between two or more multi-core devices intermediary between a client and a server. A first multi-core device may receive a hash key of a second multi-core device for mapping packets to cores of the second multi-core device. The first device may identify a core of the second device using (i) the hash key of the second device and (ii) tuple information corresponding to a connection between the client and the server via the first device. The first device may determine that the identified core is not a desired core for providing a failover connection. The first device may modify the tuple information so as to identify the desired core when used with the hash key of the second device. The first device may use the modified tuple information to establish the failover connection.

    摘要: A system, method, and computer readable medium for asynchronous live migration of applications between two or more servers. The computer readable medium includes computer-executable instructions for execution by a processing system. Primary applications runs on primary hosts and one or more replicated instances of each primary application run on one or more backup hosts. Asynchronous live migration is provided through a combination of process replication, logging, barrier synchronization, checkpointing, reliable messaging and message playback. The live migration is transparent to the application and requires no modification to the application, operating system, networking stack or libraries.

    摘要: Methods and systems for quickly serving documents are provided. Documents may be served to users, for example, in response to search query inputs. Documents may be individually communicated to a document server individually prior to batching the documents. In such a real-time serving system, serving components may fail. To ensure real-time serving despite the failure, spares are utilized to replace the failing serving components such that the spare can immediately begin receiving documents. The spare can also be synchronized with other serving components to obtain the memory of the failing serving component prior to the failure.
