Quickly reacquirable locks
Techniques are provided for quickly reacquiring mutual exclusion locks (QRLs), such as in the case in which a single process repeatedly acquires and releases the lock and in which no other process attempts to acquire the same lock. When the first holder of a QRL first acquires the lock, it biases the lock to itself. Bias may be directed in different way or at different times in some realizations. Biasing may involve a one-time compare-and-swap instruction. Thereafter, this bias-holder can reacquire and release the lock free of atomic read-modify-write operations. If a second process attempts to acquire a QRL, then the lock may revert to a “default lock”. Any standard mutual exclusion lock may be used as the default lock. A QRL lock may be reinitialized so that it can be rebiased. Rebiasing may be valuable in the case of migratory data access patterns. |

Synchronous detection and signaling of memory quota violations for sequential memory allocation in a shared heap
One embodiment of the present invention provides a method and a system for synchronous detection and signaling of memory quota violations for sequential memory allocation in a shared heap. The system detects a potential quota violation if a check of approximate memory usage indicates that an attempt to allocate memory may violate a task's memory quota. Upon detecting such a potential quota violation, the system proceeds to reconcile the task's exact memory usage. If the task's exact memory usage violates the task's memory quota, the system signals a synchronous quota violation at the time of the violation. Synchronously signaling quota violations in this manner provides accurate quota violation detection and signaling without reducing the performance of sequential memory allocation. The method also improves the accuracy of approximate per-task memory usage tracking by reconciling exact memory usage when an estimate of the task's memory usage exceeds the task's memory quota. |

Media cache control interface
The apparent speed with which a media work is ripped to copy the work into a visible store is substantially reduced. When the media work is played, its content is cached onto a persistent, fast access storage media. If the user subsequently decides to rip the media work, the content of the cache is copied to a visible store in substantially less time than would be required to play the media work and convert it. The user thus perceives that the media work is ripped in a substantially shorter time, compared to that required for ripping the media work in a conventional manner. The ripping process may encode or transform the format of the content to a desired format for use within the visible store. Constraints may be imposed by the user to limit the cache, or the caching process may be hidden from the user. |

Swarm location service for mobile ad hoc network communications
A Swarm Autonomous Routing Algorithm (SARA) is performed by simple communication node devices for node to node communications in a network, especially a Mobile Ad hoc NETwork (MANET). Each node maintains a table of pheromone values for known neighbor nodes. Pheromone values are dynamic for adapting to a dynamic arrangement of nodes, and are updated either passively or actively. Routing tables are not used. When a node receives a packet, it uses the pheromone table to simply determine whether or not to forward (rebroadcast) the packet to a neighbor node, and if possible, determines and indicates the best neighbor node for next forwarding the packet. Destination Zone Routing (DZR) and Swarm Location Service (SLS) are alternative enhancements of SARA that can be used for more efficient routing when nodes are location aware/knowledgeable. SLS may also be used to improve routing algorithms other than SARA. |
