摘要： Methods and systems for managing data redundancy include registering certified commands, input files, output files, and arguments in an execution history list after execution of said certified commands. An existing output file is provided in response to execution of a first certified command that matches an entry in the execution history list. A file is deleted if the file is reproducible from another file using a second certified command. The deleted file is registered in a reproducible file list. The deleted file is reproduced upon request using the second certified command.

摘要： A first record group and a second record group having a tree structure are merge-sorted. The first record group and the second record group are acquired, and depth information indicative of the hierarchical depth of the tree structure is attached as metadata to key information on each node of each record included in the acquired first record group and second record group. The depth information is compared in preference to the key information to perform merge sort sequentially.

摘要： A computer-implemented method is provided for refreshing cells in a Non-Volatile Memory (NVM)-based neuromorphic circuit wherein synapses are each composed of a respective cell pair formed from a respective Gp cell and a respective Gm cell of the cells. The method includes randomly selecting multiple neurons and reading a conductance of any of the synapses connected to the multiple neurons. The method further includes selecting any of the synapses connected to the selected multiple neurons for which the Gm conductance has reached a maximum conductance. The method also includes resetting the Gp cell and Gm cell of the selected synapses, and setting, at most, one of the Gp cell and Gm cell of each of the selected synapses to recover an effective total weight of each of the selected synapses.

摘要： A method for executing native code in a distributed Java Virtual Machine (JVM) is disclosed herein. The method may include receiving, in a first thread executing in a remote execution container, a first native code-generated call, such as a Java Native Interface (JNI) call, to a second thread, the first call including a first array write request. The first call may be stored in an instruction cache and bundled with a second native code-generated call and sent to the second thread. The calls are unbundled and executed in the second thread. An opaque handle to an array returned by the second call is bundled with corresponding array data and returned to the first thread. The array data of the bundle is stored in a data cache and retrieved in response to requests for the array data addressed to the second thread. A corresponding computer program product is also disclosed.

摘要： Methods and systems for refactoring a problem include refactoring an original problem having a dimension that cannot be broken into an integer number of portions, each portion having a number of problem elements equal to a size of a systolic array, into a new problem having a dimension that can be broken into an integer number of portions, each portion having a number of problem elements equal to the size of the systolic array. The new problem is solved with the systolic array. The systolic array has a size defined by an integer number of processing elements and is configured to solve portions of problems having a number of problem elements equal to the number of processing elements.
