Abstract: A method of dynamically optimizing decision tree inference is provided. The method, which is performed at the computerized system, repeatedly executes one or more decision trees for inference purposes and repeatedly performs an optimization procedure according to two-phase cycles. Each cycle includes two alternating phases, i.e., a first phase followed by a second phase. The decision trees are executed based on a reference data structure, whereby attributes of nodes of the decision trees are repeatedly accessed from the reference data structure during the first phase of each of the cycles. First, the accessed attributes are monitored during the first phase of each cycle, which leads to update statistical characteristics of the nodes. Second, a substitute data structure is configured during the second phase of each cycle based on the updated statistical characteristics. Third, the reference data structure is updated in accordance with the substitute data structure.

Abstract: A computer-implemented method, according to one embodiment, is for integrating magnetic tape storage with a distributed disk file system. The computer-implemented method includes: registering for a subset of data operations that are recorded at a central location, where the central location is coupled to a plurality of distributed accessor nodes. A subset of available resources in one or more magnetic tape libraries that are coupled to the plurality of distributed accessor nodes are registered for and further managed. Moreover, a performance of the subset of data operations using the registered subset of available resources is scheduled. Supplemental data operations which correspond to the subset of data operations are also automatically received from the central location.

Abstract: A parking assistance system for a motor vehicle includes a monitoring unit for detecting an object in the vicinity of the vehicle and a light system connected to the monitoring unit and configured to emit light into the area surrounding the motor vehicle. The monitoring unit is configured to sense the bearing of an object and to control the distribution of the light emitted from the light system as a function of the sensed bearing.

Abstract: A key-value store for storing and retrieving user files based on key-value pairs, hereafter referred to as KVPs. For each user of the key-value store, each file of a set of files of said each user is stored as one or more pairs of KVPs. Each of said one or more pairs comprises a KVP of a first type and a KVP of a second type. The KVP of the first type comprises at least a part of contents of said each file, whereas the KVP of the second type comprises metadata (and possibly attributes) of said each file. Each KVP of the second type links to one or more KVPs of the first type. Further provided are related method and computer program products.

Abstract: A multi-tiered file locking service provides file locking at the thread and process level, and can optionally include locking at the file system level. A local locking mechanism maintains a list of local locks for threads within a process. When a thread requests a lock for a file, and a local lock is obtained, a process lock for the file may be requested. When no file system locking is used, when the process lock is obtained, the thread receives the lock for the file. When file system locking is used, when the process lock is obtained, a file system lock for the file may be requested. When the file system lock for the file is obtained, the thread receives the lock for the file. The result is a file locking service that functions across threads, processes and nodes in a distributed computing environment.

Abstract: A system according to one embodiment includes a processor and logic integrated with and/or executable by the processor. The logic is configured to cause the processor to store hierarchically-organized global configuration information for each node and each tape library resource in a storage cluster to at least one memory accessible by each node of the storage cluster. The storage cluster includes at least one tape library. Also, the logic is configured to cause the processor to migrate data to and/or recall data from a tape cartridge pool within a tape library, using the hierarchically-organized global configuration information and via a node which has access to the tape cartridge pool, in response to receiving a migration and/or recall request at any node of the storage cluster. Other systems, methods, and computer program products for management of data and resources in a tiered data storage system are described in more embodiments.

Abstract: In a general embodiment, a method includes storing hierarchically-organized global configuration information for each node and each tape library resource in a storage cluster to at least one memory accessible by each node of the storage cluster, the storage cluster comprising at least one tape library. The method further includes migrating and/or recalling, using the hierarchically-organized global configuration information, data to and/or from a tape cartridge pool within a tape library. The migration or recall is performed by an appropriate node of the storage cluster and in response to receiving a migration or recall request at an arbitrary node of the storage cluster.

Abstract: A system for controlling functions of a vehicle by speech is disclosed. The system includes a mobile terminal of a network, speech processor for converting recorded speech into digital characters, and a vehicle-based interface. The mobile network terminal includes a microphone for recording a user's speech, and a terminal interface for communication with the vehicle-based interface. The vehicle-based interface is connected to a subsystem of the vehicle for controlling it based on messages received from the mobile network terminal. The mobile network terminal is adapted to process a string of digital characters derived from the user's speech into a message and to transmit said message to the vehicle-based interface.
