    摘要： Method and system for moving an object from a source partition server to a target partition server in a distributed file system having multiple partition servers. Each object has at least one associated and linked parent object, and each partition server owns a subset of objects of the file system. The object migration is accomplished by creating a copy in a target partition server of a selected object from a source partition server. At the source partition server, a forwarding link is created that references the copy in the target partition server. The copy is linked to the parent object of the selected object, and requests for access to the selected object are responded to with the forwarding link.

    摘要： A computer-implemented method for classifying alignments of paired nucleic acid sequence reads is disclosed. A plurality of paired nucleic acid sequence reads is received, wherein each read is comprised of a first tag and a second tag separated by an insert region. Potential alignments for the first and second tags of each read to a reference sequence is determined, wherein the potential alignments satisfies a minimum threshold mismatch constraint. Potential paired alignments of the first and second tags of each read are identified, wherein a distance between the first and second tags of each potential paired alignment is within an estimated insert size range. An alignment score is calculated for each potential paired alignment based on a distance between the first and second tags and a total number of mismatches for each tag.

    摘要： Techniques for watching a location of a device with respect to a destination target include obtaining a current location of a device from a localization operation, calculating an interval, and performing a next localization operation after the interval has expired. The interval may be calculated based on a velocity and a distance from the current location to a destination target. The techniques may also include calculating a displacement distance from the current location and adjusting the interval based on the displacement distance to thereby adjust a time for performing the next localization operation. The techniques may include performing state detection to determine a motion state of the device and performing the next localization operation based on the determined motion state.

    摘要： An emulation system, method, and computer program product are provided for passing system calls to an operating system for direct execution. In operation, a file is loaded into memory and instructions associated with the loaded file are emulated. Furthermore, system calls resulting from the emulation are identified. Still yet, at least a portion of the system calls are passed to an operating system for direct execution thereof. In addition, application programming interfaces are provided for external components to access, to monitor and to control the aforementioned system.

    摘要： Analyzing and detecting soft hang program errors may lead to suggestions for either curing the programming errors at runtime or refactoring the source code. For instance, responsive function invocation patterns and blocking function invocation patterns may be used to detect soft hang program errors in a source code file. Deductive database rules may be compiled from the responsive and blocking function invocation patterns to find matching function invocations in a call graph.

    摘要： Collection-based object replication for a system that includes a client computing device (client) connected to a server and multiple data storage nodes. In certain cases, a data storage node generates a replica of multiple replicas of a collection. The collection is a unit of data placement, access, replication, and repair. Other data storage nodes are also configured with a respective replica of the multiple replicas. The data storage node verifies whether an object received directly from the client for storage in the collection has been fully replicated by the other data storage nodes in respective replicas.
