摘要： A plurality of array partitions are defined for use by a set of tasks of the program run-time. The array partitions can be determined from one or more arrays that are utilized by the program at run-time. Each of the plurality of computing devices are assigned to perform one or more tasks in the set of tasks. By assigning each of the plurality of computing devices to perform one or more tasks, an objective to reduce data transfer amongst the plurality of computing devices can be implemented.

摘要： A continuing analytics method includes distributing continuous analytics tasks among a number of workers. The workers execute the tasks on data elements stored in a distributed data storage system. Executing a task changes the data elements. In response to the change, a worker that executed a task invokes an update to the data storage system. The worker then increments a version number related to the changed data element, updates the data elements, and notifies other workers of the updated data element.
摘要翻译： 持续的分析方法包括在多个工作人员之间分配连续的分析任务。 工作人员对存储在分布式数据存储系统中的数据元素执行任务。 执行任务会更改数据元素。 响应于该更改，执行任务的工作人员调用对数据存储系统的更新。 然后，工作人员增加与更改的数据元素相关的版本号，更新数据元素，并向其他工作人员通知更新的数据元素。

摘要： An embodiment provides a system and method for transaction commitment and replication. The method includes receiving a minitransaction from a client node at one or more memory nodes, wherein each memory node includes a number of replicas. The minitransaction is a type of transaction which atomically executes any combination of reading, comparing, and writing to any of a number of memory locations. The method also includes determining, for a leader of the replicas within a memory node, whether the leader is able to commit the minitransaction and stabilizing state changes of the minitransaction within a transaction log using a consensus procedure to update the replicas. The method further includes committing the minitransaction if, at each memory node, a quorum of the replicas is able to stabilize the minitransaction, or aborting the minitransaction otherwise.

摘要： An embodiment provides a method for server replication and transaction commitment. The method includes receiving a transaction from a client node at one or more memory nodes, each memory node comprising a number of replicas, and determining, for each one of the replicas, whether the replica is able to commit the transaction. The method also includes sending a response from each of the replicas to a consensus node, wherein the consensus node is configured to record whether the response is a commit response. The method further includes committing the transaction if, at each memory node, a quorum of the replicas is able to commit the transaction, and aborting the transaction otherwise.
摘要翻译： 实施例提供了用于服务器复制和事务承诺的方法。 该方法包括从一个或多个存储器节点处的客户端节点接收事务，每个存储器节点包括多个副本，并且针对每个副本确定副本是否能够提交事务。 该方法还包括将来自每个副本的响应发送到共享节点，其中，所述共享节点被配置为记录所述响应是否是提交响应。 该方法还包括提交交易，如果在每个存储节点处，副本的法定人数能够提交交易，否则中止该交易。

摘要： A distributed balanced tree having a plurality of nodes distributed across a plurality of servers is accessed. Version information associated with a node of the distributed balanced tree is retrieved. Validity of a lookup transaction performed on the balanced tree is determined by verifying a version value of only the leaf node accessed during the lookup operation against the retrieved version information.

摘要： A transactional memory system uses a volatile memory as primary storage for transactions. Data is selectively stored in a non-volatile memory to impart durability to the transactional memory system to allow the transactional memory system to be restored to a consistent state in the event of data loss to the volatile memory.

摘要： Computer-implemented systems and associated operating methods implement a fast join for databases which is adapted for usage with flash storage. A system comprises a processor that performs a join of two tables stored in a storage in pages processed in a column orientation wherein column values for all rows on a page are co-located in mini-pages within the page. The processor reduces input/output operations of the join by accessing only join columns and mini-pages containing join results.
