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： Embodiments include methods, apparatus, and systems for snapshots in distributed storage systems. One method of software execution includes using a version tree to determine what data blocks are shared between various storage nodes in the version tree in order to create a clone or a snapshot of a storage volume in a distributed storage system that uses quorum-based replication.

摘要： New failure detector mechanisms particularly suitable for use in asynchronous distributed computing systems in which processes may crash and recover, and two crash-recovery consensus mechanisms, one requiring stable storage and the other not requiring it. Both consensus mechanisms tolerate link failures and are particularly efficient in the common runs with no failures or failure detector mistakes. Consensus is achieved in such runs within 3□ time and with 4n messages, where □ is the maximum message delay and n is the number of processes in the system.
