Patent number: 10044505Abstract: A node in a distributed computing environment can generate key-value pairs. The node can categorize the key-value pairs into bins, with each key-value pair being categorized into a bin spanning a range of hashed keys that includes a hashed key of the key-value pair. The node can determine nodes in the distributed computing environment that are mapped to the bins. The node can distribute each key-value pair to a node corresponding to a bin into which the key-value pair was categorized. The node can then sort any of the key-value pairs maintained on the node by hashed key or key to generate sorted key-value pairs. The node can assign index values to the sorted key-value pairs. The indexed key-value pairs may be the same each time the above process is run, regardless of the underlying topology of the distributed computing environment. This can result in stable data-processing.Type: GrantFiled: August 15, 2017Date of Patent: August 7, 2018Assignee: SAS INSTITUTE INC.Inventor: Gang Meng

Patent number: 9529837Abstract: This disclosure describes methods, systems, computer-readable media, and apparatuses for calculating a summary statistic. Calculating the summary statistic can be performed by identifying multiple subsets of a set of variable observations and assigning the subsets to grid-computing devices such that no two of the subsets are assigned to a same one of the grid-computing devices. A parallel processing operation that involves multiple processing phases at each of the grid-computing devices is then coordinated. The parallel processing operation includes each of the grid-computing devices inventorying the respectively assigned subset and generating inventory information representative of the respectively assigned subset. Subsequently, the inventory information generated by the grid-computing devices is received, and a summary statistic is determined by synthesizing the received inventory information.Type: GrantFiled: May 5, 2014Date of Patent: December 27, 2016Assignee: SAS Institute Inc.Inventor: Gang Meng
