摘要： Approaches for recovering a node of a distributed transactional system. When a recovering node is being brought on-line, a copy of at least a portion of a first data store maintained by an existing node is created without ceasing to process transactions against the first data store at the existing node. The recovering node creates a second data store based on the copy of the first data store. While the recovering node creates the second data store, the recovering node stores committed transaction data received from a plurality of nodes. The committed transaction data describes transactions committed against data stores maintained by the sender of the committed transaction data. The recovering node may thereafter replay, against the second data store, any transactions identified by the committed transaction data that are associated with a global transaction number that is more recent than is a reference commit number.

摘要： A system and method for sending a cache line of data in a single message is described. An instruction issued by a processor in a multiprocessor system includes an address of a message payload and an address of a destination. Each address is translated to a physical address and sent to a scalability interface associated with the processor and in communication with a system interconnect. Upon translation the payload of the instruction is written to the scalability interface and thereafter communicated to the destination. According to one embodiment, the translation of the payload address is accomplished by the processor while in another embodiment the translation occurs at the scalability interface.
