摘要： Iterate-aggregate shape queries are executable in an efficient parallel manner. Techniques are utilized that leverage properties of aggregations to implement such a query in a highly parallelized manner utilizing one or both of vertical and horizontal parallelism. More specifically, queries can be recursively evaluated in parallel utilizing partitioning and repartitioning mechanisms. Distributed query execution results over a subset of input data are repartitioned and aggregated to produce a final result.

摘要： Data layout optimization arranges data members within memory to enhance software performance. Profiling data is consulted to determine how to group data members for an object class into groups. One technique groups the data members based on how frequently the data members are referenced in memory. Another technique groups the data members based on their affinities for one another in time as determined by observing when references to the data members take place. A variety of options when collecting the profiling data and grouping the data members is supported. The data member grouping is recorded in metadata associated with a definition of the object class. At runtime, a class loader places the data members of an object in memory according to the metadata. Data members of different groups can be placed in separately-loadable units of memory in the memory system. Subsequently, when the data members are referenced in memory, more frequently referenced data members, including those that tend to be referenced at times close to each other, reside at neighboring locations in the memory system.
摘要翻译： 数据布局优化将数据成员安排在内存中以增强软件性能。 查询分析数据以确定如何将对象类的数据成员分组。 一种技术根据数据成员在内存中引用的频率来对数据成员进行分组。 另一种方法是根据数据成员的相关性在时间上对数据成员进行分组，通过观察对数据成员的引用进行确定。 支持收集分析数据和分组数据成员时的各种选项。 数据成员分组被记录在与对象类的定义相关联的元数据中。 在运行时，类加载器根据元数据将对象的数据成员放置在内存中。 不同组的数据成员可以被放置在存储器系统中的可分离的存储单元中。 随后，当在存储器中引用数据成员时，更频繁地引用的数据成员（包括倾向于在彼此接近的时间被引用的数据成员）驻留在存储器系统中的相邻位置处。

摘要： Separable integration is provided for simulation contexts where modeling and integration can be considered separately when programmatically implementing the simulations, for example. Thus, modeling concepts can be defined relating to the simulation, and integration of the modeling concept can happen separately to provide more variety to meet modeling specifications. In one embodiment, a state-space form equation can be computed for a modeling concept equation (an equation of motion, for example) and an integration scheme can be applied to the state-space form equation regardless of the modeling equation from which it was computed. In this regard, integration can be focused on to provide a plurality of schemes for different contexts, for example.

摘要： A spectrum of tier-splitting mechanisms facilitates distributed programming. A rich application model and associated tools enable programmers to write rich distributed applications that can run anywhere. A program can be developed simply as a single tier or tier agnostic application. Subsequently or concurrently, the program can be sliced into multiple tiers in different ways to reflect, for instance, capabilities and/or constraints of a server, client and/or network.

摘要： A compositional application programming interface (API) permits non-sequential construct declaration independent of other API calls. A wrapper is applied to an imperative API to provide a compositional interface that enables arbitrary and autonomous construct declaration. Additionally, a literal syntax (e.g., code literals, graphic literals . . . ) affords a convenient declaration mechanism for such constructs.

摘要： The claimed subject matter provides a system and/or a method that facilitates addressing complex modeling. An entity data model that can receive data via an interface and that formalizes a notion of at least one of a Relationship, a Relationship instance, and a Relationship Set in a manner substantially similar to at least one of an Entity type, an Entity instance, and an entity-set respectively, wherein a semantic related to the at least one of the Relationship, the Relationship instance, and the Relationship Set are captured as metadata in the same manner as metadata is captured for at least one of the Entity type, the Entity instance, and the Entity-set, respectively.

摘要： Techniques for representing and publishing an interactive document useful for analyzing data. The document may be represented as a directed acyclic graph of entities interconnected by edges. The entities may be of multiple types. Yet, a broad range of interactive documents may be represented by a limited number of types of entities and the capabilities to interconnect entities of different types and to share a data schema across entities of different types. A tool may enable a user to author such documents. The tool may also facilitate publishing of the document. For publishing, the document may be converted to an executable form. Prior to such a conversion, the graph may be modified for more efficient processing. The graph may also be partitioned such that portions of the graph, when distributed across tiers of a computing system, such as a cloud-based platform, execute on computing devices that provide efficient operation.
摘要翻译： 用于表示和发布用于分析数据的交互式文档的技术。 文档可以被表示为通过边缘互连的实体的有向非循环图。 实体可以是多种类型。 然而，广泛的交互式文档可以由有限数量的实体类型表示，并且能够互连不同类型的实体并且跨越不同类型的实体共享数据模式。 一个工具可以使用户能够提供这样的文档。 该工具还可以促进文档的发布。 对于发布，文档可能会转换为可执行形式。 在进行这种转换之前，可以修改图表以进行更有效的处理。 该图也可以被分区，使得当分布在诸如基于云的平台的计算系统的层上时，图的部分在提供有效操作的计算设备上执行。

摘要： Interactive and dynamic exploring of filter criteria for large amounts of numerical data having multiple dimensions is described. Exploration occurs without excessive amounts of computation or querying of a database based on a data set summary that may be obtained from a server in a search system and applied by a client device. A data set is summarized so as to capture relationships between distributions of items in the data set along multiple dimensions. To explore filter criteria, a user may interactively adjust a range of values that act as a filter criteria along a dimension and determine an effect on a distribution of items along another dimension. The client device may apply the data summary in reverse to determine, based on user input specifying aspects of a distribution along one dimension, filter criteria for another dimension that would result in the specified distribution.
