摘要： A transactional shared memory system has a plurality of discrete application nodes; a plurality of discrete memory nodes; a network interconnecting the application nodes and the memory nodes, and a controller for directing transactions in a distributed system utilizing the shared memory. The memory nodes collectively provide an address space of shared memory that is provided to the application nodes via the network. The controller has instructions to transfer a batched transaction instruction set from an application node to at least one memory node. This instruction set includes one or more write, compare and read instruction subsets, and/or combinations thereof. At least one subset has a valid non null memory node identifier and memory address range. The memory node identifier may be indicated by the memory address range. The controller controls the memory node responsive to receipt of the batched transaction instruction set, to safeguard the associated memory address range during execution of the transaction instruction set. The batched transaction instruction set is collectively executed atomically. A notification instruction set may also be used to establish a notification, triggered upon a subsequent write event upon at least a portion of a specified address range.

摘要： Provided is a system and method for directing group communication in a system environment that has a plurality of discrete application nodes networked with at least one discrete memory node, establishing a shared memory providing a passive message queue. A code library permits an application node member of a group to assemble a message selected from the group of send, join, leave, or read. The send, join and leave messages permit a first application node to add a message to the queue for all members of a group including the first application node at the time the message was added. The instruction set permitting the addition of the message is executed atomically.

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.

摘要： According to one embodiment, a method comprises evaluating messages between nodes of a distributed computing environment. Based on timing relationships of the messages, probability of causal links between pairs of messages determined. Based on the determined probability, at least one causal path comprising a plurality of causal links is inferred. Further, an overall probability that the inferred causal path is accurate is determined. In certain embodiments, the overall probability is output for the corresponding causal path to provide an indication of the confidence of the accuracy of such inferred causal path.

摘要： In accordance with an embodiment of the invention, a method of writing and reading redundant data is provided. Data is written by storing a copy of the data along with a timestamp and a signature at each of a set of storage devices. The data is read by retrieving the copy of the data, the timestamp and the signature from each of a plurality of the set of data storage devices. One of the copies of the data is selected to be provided to a requestor of the data. Each of the storage devices of the set is requested to certify the selected copy of the data. Provided that a proof of certification of the selected copy of the data is valid, the storage devices of the set are instructed to store the selected copy of the data along with a new timestamp.
