摘要： A system includes an initiator and processing nodes. The initiator distributes portions of a transaction among the processing nodes. Each processing node has at least one downstream neighbor to which the processing node sends commit messages. The commit messages include a commit status of the processing node. The downstream neighbor is also a processing node.

摘要： In one example, a method for implementing recovery segments includes sending an application message from a parent process executed by a first computing device to a child process executed by a second computing device and identifying a dependency created by the application message. This identified dependency is included in a dependence set of the child process and saved. A checkpoint is generated by the parent process and a checkpoint message that includes dependency information is sent from the parent process to the child process. The child process modifies the dependence set according to the dependency information and generates a second checkpoint that is saved in nonvolatile memory of the second computing device. Upon occurrence of a failure of the parent process, the child process reverts to a most recent checkpoint generated by the child process that does not include the effects of processing an orphan message.

摘要： A shiftable memory supporting atomic operation employs built-in shifting capability to shift a contiguous subset of data from a first location to a second location within memory during an atomic operation. The shiftable memory includes the memory to store data. The memory has the built-in shifting capability. The shiftable memory further includes an atomic primitive defined on the memory to operate on the contiguous subset.

摘要： A computer apparatus and related method to reduce database congestion is provided. In one aspect, the computer apparatus and method may generate a new partition within a hierarchical data structure of interlinked nodes, if a distribution of key values stored in the hierarchical data structure is skewed in favor of a range of key values.

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： To access data, a distributed balanced tree having nodes distributed across plural servers is accessed. Version information is associated with the nodes of the distributed balanced tree. During an operation that accesses the distributed balanced tree, the version information is checked to determine whether content of one or more nodes of the distributed balanced tree has changed during the operation.
