A computing method includes accepting a notification of a computing task for execution by a group of compute nodes interconnected by a communication network, which has a given interconnection topology and includes network switching elements. A set of preferred paths, which connect the compute nodes in the group via at least a subset of the network switching elements to one or more root switching elements, are identified in the communication network based on the given interconnection topology and on a criterion derived from the computing task. The network switching elements in the subset are configured to forward node-level results of the computing task produced by the compute nodes in the group to the root switching elements over the preferred paths, so as to cause the root switching elements to calculate and output an end result of the computing task based on the node-level results.

A “peer-to-peer” hierarchical routing protocol—also referred to as Zone-based Hierarchical Link State Routing protocol (or “ZHLS”)—which incorporates location information into a novel “peer-to-peer” hierarchical routing approach. The network may be divided into non-overlapping zones. Aggregating nodes into zones conceals the detail of the network topology. Initially, each node knows its own position and therefore zone ID through a position determination unit, such as a Global Positioning System (GPS). After the network is established, each node knows the low level (node level) topology about node connectivity within its zone and the high level (zone level) topology about zone connectivity of the whole network. A packet may be forwarded by specifying the hierarchical address—zone ID and node ID—of a destination node in the packet header.

A system and method for diagnosing faults in a communication network using a distributed alarm correlation system. The alarm correlation system may include node-level alarm correlation tools (ACTs) located at nodes in the network to provide node-level alarm correlation producing node-level correlation results.

Each of the node-level ACTs may also share the diagnostic knowledge and the node-level correlation results with a higher-level ACT. The higher-level ACT may provide higher-level alarm correlation to produce higher-level correlation results.

NUMA-aware reader-writer locks may leverage lock cohorting techniques to band together writer requests from a single NUMA node. The locks may relax the order in which the lock schedules the execution of critical sections of code by reader threads and writer threads, allowing lock ownership to remain resident on a single NUMA node for long periods, while also taking advantage of parallelism between reader threads. Threads may contend on node-level structures to get permission to acquire a globally shared reader-writer lock. Writer threads may follow a lock cohorting strategy of passing ownership of the lock in write mode from one thread to a cohort writer thread without releasing the shared lock, while reader threads from multiple NUMA nodes may simultaneously acquire the shared lock in read mode. The reader-writer lock may follow a writer-preference policy, a reader-preference policy or a hybrid policy.

In a server a source document is represented as a source document object model (13). For delivery of the source document to a user device such as a mobile phone the server dynamically selects transformation maps (10) and merges them to provide a compound map (12). The maps (10) are selected according to characteristics of the delivery channel and of the user device. The source DOM (13) is then transformed into a target DOM (14) in a single pass. Each node of the source DOM (13) self-transforms using the map rules. At the node level the transformation may change node attributes and / or node-to-node relationships.

A method for determining a physical address from a virtual address, wherein a mapping regulation between the virtual address and the physical address is implemented as hierarchical tree structure with compressed nodes. First, a compression indicator included in the mapping regulation is read, and a portion of the virtual address associated with the considered node level is read. Using the compression indicator and the portion of the virtual address, an entry in the node list of the considered node is determined. The determined entry is read, whereupon the physical address can be determined directly, if the considered node level has been the hierarchically lowest node level. If higher node levels to be processed are present, the previous steps in determining the physical address for compressed nodes of lower hierarchy level are repeated until the hierarchically lowest node level is reached.

The invention discloses a redundancy management method for improving the availability of a monitoring pair based fault tolerant system. The method comprises the steps of intra-node voting and monitoring and node-level voting and monitoring. During the intra-node voting and monitoring, a controller A and a controller B are consistent by comparison and data of the controller A are selected to enter the node-level voting and monitoring. During the node-level voting and monitoring, a mid-value is selected as a reference value of monitoring from values of three signals of three nodes, and if a difference between other two non mid-value signals and a mid-value signal is within a threshold range, then the non mid-value signals are normal, otherwise, the non mid-value signals are faulted. According to the redundancy management method, the redundancy management of a monitoring pair based three-node or two-node fault tolerant computer is realized; the credibility of system data of a fault tolerant computer system can be ensured; and compared with fault silence based monitoring pair fault tolerance, the redundancy degradation of the system is slowed down, and a backup controller can be reconfigured to be a main controller when a fault occurs once in a node through a software and hardware combination mode, so that the system is ensured not to be degraded.
