摘要: Program partitioning of an application can include creating execution flow graphs and static flow graphs of targeted functions or operations of the application. Based on the execution flow graphs or static flow graphs, replay interfaces are created. The replay interfaces provide data flows that are usable in re-execution of the application during program development.

摘要: Data-parallel computation programs may be improved by, for example, determining the functional properties user defined functions (UDFs), eliminating unnecessary data-shuffling stages, and/or changing data-partition properties to cause desired data properties to appear after one or more user defined functions are applied.
摘要翻译: 可以通过例如确定用户定义的功能(UDF)的功能属性,消除不必要的数据混洗阶段和/或改变数据分区属性来改进数据并行计算程序,以使期望的数据属性在一个或多个 应用用户定义的功能。

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.
