摘要: Systems and methods for generating distributed dataflow graphs and processing data elements in parallel utilizing the distributed dataflow graphs are provided. A sequential dataflow graph is formed from incoming data elements, and a variety of heuristics is applied to the sequential dataflow graph to determine which of the data transformation steps within the graph are capable of being processed multiple times in parallel. Once determined, the sequential dataflow graph is divided into subgraphs, which are then replicated, e.g., based on available resources and.or external constraints. The resulting subgraphs are connected, based on the semantics of each vertex, and a distributed dataflow graph is generated, which can efficiently process data elements, for instance, for data warehousing and the like.

摘要: Computer-readable media, systems, and methods for building a multidimensional data cube having one or more high-cardinality attributes are described. In embodiments, data is extracted from one or more databases. It is determined that one or more instances of the data are fact data and one or more instances of the data are dimension data. Each member of the fact data is one instance of a dimension and each instance of the dimension data includes an attribute for grouping the fact data. Moreover, in embodiments it is determined that one or more instances of the dimension data are high-cardinality attributes. The one or more high-cardinality attributes are processed with fact data and stored in fact tables on a computer storage medium.

摘要: A decoder is disclosed that can reduce power consumption at different stages of a decoding process. At a first stage where the decoder calculates residual values, the decoder can reduce power consumption by calculating residual values using less than a full set of division circuits. A reduced number of division circuits may be sufficient to successfully calculate residuals associated with the codeword to complete the decoding process. Division circuits that are not used may be disabled to reduce power consumption. At another stage of the decoding process where the decoder generates coefficients that are used to identify locations of errors in the codeword, the decoding process can limit power consumption by reducing the number of iterations of a polynomial generator by incorporating termination decision circuitry.
