摘要： A method for distributed computing includes processing multiple sets of data at respective computing nodes (24), and calculating respective local values of one or more statistical parameters characterizing the sets of the data. A global condition is defined, such that the condition is violated when a function defined over a weighted average of the respective local values crosses a predetermined threshold. The global condition is separated into a plurality of local constraints, which include a respective local constraint to be evaluated by each of the nodes based on the respective local values, such that violation of the respective local constraint in at least one of the nodes indicates a violation of the global condition. The local constraint is evaluated independently at each of the nodes. When at least one of the nodes detects that the respective local constraint is violated, an indication that the global condition has been violated is produced.
摘要翻译：一种用于分布式计算的方法包括：处理各个计算节点（24）处的多组数据，以及计算表征数据集的一个或多个统计参数的各自本地值。定义全局条件，使得当在相应局部值的加权平均值上定义的功能跨越预定阈值时，该条件被违反。全局条件被分成多个局部约束，其包括基于各个本地值由每个节点评估的相应的局部约束，使得至少一个节点上的相应局部约束的违反指示违反全球条件。每个节点独立地评估局部约束。当至少一个节点检测到相应的本地约束被违反时，产生了全局条件已被违反的指示。

摘要： A method for discovering association rules in a distributed database that includes a plurality of partitions associated with respective computing nodes includes generating a candidate association rule defining an association relationship between itemsets in the distributed database. At each node among at least a subset of the nodes, an asynchronous fully-distributed majority voting process is applied to assess a correctness of the candidate association rule.
摘要翻译：一种用于发现包括与各个计算节点相关联的多个分区的分布式数据库中的关联规则的方法包括生成定义分布式数据库中的项集之间的关联关系的候选关联规则。在节点的至少一个子集中的每个节点处，应用异步完全分配的多数投票过程来评估候选关联规则的正确性。
