    • A system and method for test generation for system level verification using parallel algorithms are provided. The present invention generates test patterns for system level tests by exploiting the scalability of parallel algorithms while allowing for data set coloring and expected result checking. Based on the characteristics of the system being tested an iterative parallel algorithm is selected from a plurality of possible parallel algorithms. The selected parallel algorithm is then separated into separate program statements for execution by a plurality of processors. A serial version of the selected algorithm is executed to generate a set of expected results. The devised parallel version of the selected algorithm is then run to generate a set of test result data which is compared to the set of expected results. If the two sets of data match, it is determined that the system is operating correctly.
    • 提供了一种使用并行算法进行系统级验证的测试生成系统和方法。 本发明通过利用并行算法的可扩展性同时允许数据集着色和预期结果检查来生成用于系统级测试的测试模式。 基于被测系统的特征,从多个可能的并行算法中选择迭代并行算法。 然后将所选择的并行算法分离成单独的程序语句以供多个处理器执行。 执行所选算法的串行版本以产生一组预期结果。 然后运行所选算法的设计的并行版本以生成与一组预期结果进行比较的一组测试结果数据。 如果两组数据匹配,则确定系统正常运行。

    • A method for increasing performance of non-relational databases with reduction in view index sizes is provided. One or more user views are provided in addition to the master view having all hierarchical/categorized data. User views are created having a subset of this hierarchical/categorized data that significantly reduces index size and improves performance. The indexes of the user view are associated with the indexes of the master view. This method improves view caching by dividing view cache into partitions based on the types of view, each with different priorities and management techniques. The master view may have a higher priority and may be used by servers while the user view may have lower priorities and may be used by users and client applications. In this way, legacy non-relational databases may continue to be suitably maintained with acceptable performance and avoiding potential cost and risk of migrating to a relational database.
    • 提供了一种提高非关系数据库性能的方法,减少视图索引大小。 除了具有所有层次/分类数据的主视图之外,还提供一个或多个用户视图。 创建具有该分层/分类数据的子集的用户视图,显着减少索引大小并提高性能。 用户视图的索引与主视图的索引相关联。 该方法通过将视图缓存分为基于视图的类型(每个具有不同的优先级和管理技术)而将视图缓存分割成分区,从而改进视图缓存。 主视图可能具有较高的优先级,并且可能被服务器使用,而用户视图可能具有较低的优先级,并且可被用户和客户端应用使用。 以这种方式,传统的非关系数据库可能会继续适当地保持具有可接受的性能,并避免迁移到关系数据库的潜在成本和风险。
