Embodiments of the invention relate a hybrid hardware and software implementation of transactional memory accesses in a computer system. A processor including a transactional cache and a regular cache is utilized in a computer system that includes a policy manager to select one of a first mode (a hardware mode) or a second mode (a software mode) to implement transactional memory accesses. In the hardware mode the transactional cache is utilized to perform read and write memory operations and in the software mode the regular cache is utilized to perform read and write memory operations.

A self-adaptive control system based on proportional-integral (PI) control theory for dynamic capacity management of latency-sensitive application servers (e.g., application servers associated with a social networking application) are disclosed. A centralized controller of the system can adapt to changes in request rates, changes in application and/or system behaviors, underlying hardware upgrades, etc., by scaling the capacity of a cluster up or down so that just the right amount of capacity is maintained at any time. The centralized controller uses information relating to a current state of the cluster and historical information relating to past state of the cluster to predict a future state of the cluster and use that prediction to determine whether to scale up or scale down the current capacity to reduce latency and maximize energy savings. A load balancing system can then distribute traffic among the servers in the cluster using any load balancing methods.

In one embodiment, a conference bridge receives a call initiated by a first caller endpoint. The conference bridge identifies a conference to which the call requests entry and determines whether the conference bridge has available resources to process the call. The conference bridge enables the call to join the conference via a second conference bridge associated with a second caller endpoint participating in the conference according to whether the conference bridge has available resources to process the call.

Disclosed are a method and system for recovering a distributed system from a failure of a data storage unit. The distributed system includes a plurality of computer systems, each having a read-write computer and a data storage unit. Data is replicated from a particular data storage unit to other data storage units using publish-subscribe model. A read-write computer receives the replicated data, processes the data for any conflicts and stores it in the data storage unit. If a data storage unit fails, another data storage unit that has latest data corresponding to the failed data storage unit is determined and the latest data is replicated to other data storage units. Accordingly, the distributed system continues to have the data of the failed data storage unit. The failed data storage unit may be reconstructed using data from one of the other data storage units in the distributed system.

In one embodiment, a method includes a request that is obtained by a call center system from a customer. The method also includes identifying a first set of experts that includes at least a first expert suitable for, or capable of, processing the request. The first expert is offline with respect to the call center system. An offer task is created and provided to the first set of experts. The offer task identifies the request and initiates the scheduling of a callback to address the request.

In one embodiment, a processor may include a vector unit to perform operations on multiple data elements responsive to a single instruction, and a control unit coupled to the vector unit to provide the data elements to the vector unit, where the control unit is to enable an atomic vector operation to be performed on at least some of the data elements responsive to a first vector instruction to be executed under a first mask and a second vector instruction to be executed under a second mask. Other embodiments are described and claimed.

Disclosed is a technology for publishing subscriptions in a publish-subscribe system in accordance with subscription groups. The technology may include (i) determining a consumption characteristic by which each of multiple subscribers in a publish-subscribe system consumes a subscription published by a publisher; (ii) identifying the subscribers whose consumption characteristics satisfy a specified similarity criterion; (iii) defining multiple subscription groups, each of which includes subscriptions of those of the subscribers whose consumption characteristics satisfy the specified similarity criterion; (iv) storing the subscriptions in multiple logical partitions of a storage system where each of the logical partitions contains a separate non-overlapping subset of the subscriptions; and (v) transmitting the subscriptions to the subscribers in accordance with the subscription groups.

When multiple regional data clusters are used to store data in a system, maintaining cache consistency across different regions is important for providing a desirable user experience. In one embodiment, there is a master data cluster where all data writes are performed, and the writes are replicated to each of the slave data clusters in the other regions. Appended to the replication statements are invalidations for cache values for the keys whose values have been changed in the master data cluster. An apparatus in the master data cluster logs replication statements sent to the slave databases. When a slave database fails, the apparatus extracts the invalidations intended for the failed database and publishes the invalidations to a subscriber in the region of the failed database. The subscriber sends the invalidations to the local caches to cause stale data for those keys to be deleted from the caches.

System and method for implementing cache consistent regional clusters

A unified messaging system for an enterprise includes a messaging module operable to store a message sent by a first user to a second user in a first media type, and to deliver the message to the second user in either the first type or a second media type. A natural language speech parsing (NLSP) module coupled with the messaging module is operable to detect an actionable item contained within the message, the messaging module dynamically modifying a response menu to include an option corresponding to the actionable item, and then presenting the modified response menu to the second user concurrent with or following delivery of the message. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
