摘要： Synchronization services provide a concurrency-safe reader/writer lock supporting a time out feature. The lock can be implemented using lockless data structures to provide efficient synchronization services. Various features such as lock nesting and auto-transformation address common scenarios arising in componentized programs. The lock supports upgrading and suspension, and the time out feature can support an efficient, low-cost optimistic deadlock avoidance scheme. Peculiarities of the reader/writer scenario are addressed in an efficient way to maintain lock stability and consistency, thus providing synchronization services suitable for implementation at the kernel level. In one implementation using event objects, the events are managed for high efficiency and stability of the lock. For multiprocessor machines, a hybrid lock avoids a context switch by behaving as a spin lock before waiting for the lock to become available.

摘要： Resources are organized into collections to facilitate more efficient and reliable resource access. Namespace managers communicate with one another to form a federation namespace infrastructure. The infrastructure can efficiently route, migrate, and process namespace requests, such as, for example, namespace registration requests from providers requesting to manage portions of namespaces and lookup requests from consumers requesting access to managed resources. Resources can be registered in and made accessible from multiple different namespaces. Resources can be identified using nested queries that filter results at multiple levels of a hierarchical namespace.

摘要： The present invention extends to methods, systems, and computer program products for performing computations in a distributed infrastructure. Embodiments of the invention include a general purpose distributed computation infrastructure that can be used to perform efficient (in-memory), scalable, failure-resilient, atomic, flow-controlled, long-running state-less and state-full distributed computations. Guarantees provided by a distributed computation infrastructure can build upon existent guarantees of an underlying distributed fabric in order to hide the complexities of fault-tolerance, enable large scale highly available processing, allow for efficient resource utilization, and facilitate generic development of stateful and stateless computations. A distributed computation infrastructure can also provide a substrate on which existent distributed computation models can be enhanced to become failure-resilient.

摘要： A primary node is elected from among a plurality of nodes in a replica set of nodes. The primary node accepts and processes client data access requests. The replica set includes the primary node and other secondary nodes. The primary node receives client data access requests and assigns a data sequence number to each client data access request that mutates state in the order the client data access requests are received. The data sequence numbers include a linearized processing order that is followed by each of the nodes in the replica set. The primary node sends the mutating client data access requests including any corresponding data sequence numbers to the secondary nodes. The primary node receives, from a threshold number of secondary nodes, an acknowledgement indicating reception of the client data access request. The primary node commits the data mutating access request.

摘要： The present invention extends to methods, systems, and computer program products for rendezvousing resource requests with corresponding resources. Doubly linked sorted lists are traversed using modulo arithmetic in both directions. Sorted lists can be partitioned based on a multiple proximity metrics. Node routing tables provide a logarithmic index to nodes within the ID space of the federation infrastructure to facilitate more efficient routing. Messages can be routed to nodes within a ring and proximally routed to nodes in other partitioned rings.

摘要： The present invention extends to methods, systems, and computer program products for establishing and maintaining membership within a federation infrastructure. A joining node submits a join message to an existing federation infrastructure. The federation infrastructure routes the join message to a processing node. The processing node facilitates identification of predecessor, successor, neighborhood, and routing nodes (for the joining node) within a ring of nodes. The joining node exchanges messages with identified nodes to obtain state information for the identified nodes and other nodes within the ring. Nodes periodically exchange state information, including state information for other nodes, such that state information for the ring is efficiently propagated to all nodes in the ring even when communication between some nodes is lost. Instance IDs, phase values, and freshness values are used to determine when state information is stale and/or is to be updated.

摘要： Implementations of the present invention relate in part to optimizations to peer-to-peer communication systems. For example, one implementation relates to use of a smart transceiver that creates, caches, and manages communication channels dynamically between peers. Another implementation relates to use of a central tracking object that can be used to efficiently register and distribute peer messages among the various peers. In one implementation, the central tracking object is shared amongst peers in the group. Still another implementation relates to associating peer groups with namespaces, and for including peer groups of one namespace within still other peer groups of different namespaces. These and other aspects of the invention can also be used to ensure delivery intent of a given peer message is preserved, and to ensure that optimal numbers of messages are communicated to any given peer at any given time.

摘要： The present invention extends to methods, systems, and computer program products for a joining node to join a ring of nodes within a rendezvous federation. Embodiments include detecting a neighborhood of nodes on the ring of nodes. The joining node indicates its intent to take id-space ownership for a portion of the id-space between the joining node and a selected immediately adjacent node. The joining node indicates an intent to monitor the selected node. The joining node receives three indications, the first indicating acceptance of the joining node's intent to take id-space ownership for a portion of the id-space between the joining node and the selected node, the second indicating acceptance of the joining node's intent to monitor the selected node, the third indicating the first selected node's intent to monitor the joining node. The joining node indicates acceptance of the selected node's intent to monitor the joining node.

摘要： A system and method for converting code associated with synchronous method calls to code that can be employed to perform asynchronous method calls and for supporting such asynchronous method calls is provided. The system includes a pattern generator that can break code for a synchronous method call into one or more constituent parts including a begin asynchronous operation method, an end asynchronous operation method, an asynchronous call state object and an asynchronous call result object. The system includes a pattern data store that holds data associated with converting a synchronous method call to an asynchronous method call, which facilitates employing the system consistently across environments like file input/output, stream input/output, socket input/output, networking, remoting channels, proxies, web forms, web services and messaging message queues.
