摘要： A system and method for backing up data on computer-readable physical medium, especially useful for databases, such as those using POSIX standard function calls, whereby select operations performed by a user of the database are intercepted and, while performed, are also translated into a shadow file having information about a database file to be backed up and the operations performed on that file. The resulting shadow file can be used to reconstitute the database file. In another mode of operation, the system and method create a copy of the database and concurrently make the same changes to the copy as the user commands while also concurrently keeping a shadow file system related to the database copy.

摘要： A processor may operate in one of a plurality of operating states. In a Normal operating state, the processor is not involved with a memory transaction. Upon receipt of a transaction instruction to access a memory location, the processor transitions to a Transaction operating state. In the Transaction operating state, the processor performs changes to a cache line and data associated with the memory location. While in the Transaction operating state, any changes to the data and the cache line is not visible to other processors in the computing system. These changes become visible upon the processor entering a Commit operating state in response to receipt of a commit instruction. After changes become visible, the processor returns to the Normal operating state. If an abort event occurs prior to receipt of the commit instruction, the processor transitions to an Abort operating state where any changes to the data and cache line are discarded.

摘要： The poor scalability of existing superscalar processors has been of great concern to the computer engineering community. In particular, the critical-path delays of many components in existing implementations grow quadratically with the issue width and the window size. This patent presents a novel way to reimplement these components and reduce their critical-path delay growth. It then describes an entire processor microarchitecture, called the Ultrascalar processor, that has better critical-path delay growth than existing superscalars. Most of our scalable designs are based on a single circuit, a cyclic segmented parallel prefix (cspp). We observe that processor components typically operate on a wrap-around sequence of instructions, computing some associative property of that sequence. For example, to assign an ALU to the oldest requesting instruction, each instruction in the instruction sequence must be told whether any preceding instructions are requesting an ALU. Similarly, to read an argument register, an instruction must somehow communicate with the most recent preceding instruction that wrote that register. A cspp circuit can implement such functions by computing for each instruction within a wrap-around instruction sequence the accumulative result of applying some associative operator to all the preceding instructions. A cspp circuit has a critical path gate delay logarithmic in the length of the instruction sequence. Depending on its associative operation and its layout, a cspp circuit can have a critical path wire delay sublinear in the length of the instruction sequence.

摘要： A computer including a processor array and a routing network. Processors in the processor array generate messages for transfer to over the routing network, each message including a path identifier portion identifying a path from a source, message processor to a destination processor. The routing network comprises a plurality of interconnected router nodes, at least some of said router nodes being connected to the processors to receive messages therefrom and transmit messages thereto. Each router node operates in a plurality of modes. In a first mode, the router nodes couple received messages to a router node connected thereto in accordance with the path identifier portion to thereby transfer each respective message along the path identified in its path identifier portion. In a second mode, the router node couple received messages to predetermined ones of the router nodes or processors connected thereto, the predetermined ones of said router nodes or processors being selected to facilitate transfer of a message to a nearby processor to facilitate the rapid emptying of the routing network of messages. A control element controls the router nodes to enable them to operate in the first mode or second mode generally contemporaneously.

摘要： A message is generated at each of a plurality of source nodes, each message comprising at least address information identifying a first or destination node Di, and address information identifying a source node Si. The address information for the destination node is then used to route each message through the nodes of the communication network toward its destination node. At each node where two messages meet that are addressed to the same destination node, a second two messages are generated in place of the first two messages. One of these messages is routed toward the destination node while the other is routed toward an auxiliary node Ai whose address is specified in the message. If any further collisions take place between two messages routed to the same destination node, again two more messages are generated in place of the two colliding messages and one is routed toward the destination node while the other is routed toward another auxiliary node. The messages routed to the auxiliary node contain address information sufficient to route a message from the destination node to all the source nodes that originally addressed it.
摘要翻译：在多个源节点的每一个处生成消息，每个消息至少包括标识第一或目的节点Di的地址信息，以及标识源节点Si的地址信息。然后，目的地节点的地址信息用于将通过通信网络的节点的每个消息路由到其目的地节点。在两个消息满足的每个节点寻址到相同目的地节点的情况下，生成第二个两个消息来代替前两个消息。这些消息之一被路由到目的地节点，而另一个消息被路由到在消息中指定其地址的辅助节点Ai。如果在路由到同一目的地节点的两个消息之间发生任何进一步的冲突，则再次产生两个消息来代替两个冲突消息，一个路由到目的节点，而另一个被路由到另一个辅助节点。路由到辅助节点的消息包含足以将消息从目的地节点路由到最初对其寻址的所有源节点的地址信息。

摘要： A method, apparatus and computer program product for storing data in a disk storage system is presented. A dictionary data structure is defined and stored on the disk storage system. Key-value pairs can be inserted and deleted into the dictionary data structure, with full transactional semantics, at a rate that is faster than one insertion per disk-head movement. Keys can be looked up with only a logarithmic number of transfers, even for keys that have been recently inserted or deleted. Queries can be performed on ranges of key-value pairs, including recently inserted or deleted pairs, at a constant fraction of the bandwidth of the disk. The dictionary employs indirect logging for physical block logging.
