摘要： A system and method for solving the weak membership problem in a system of nodes that might include redundancies. Each node is given the same random seed. Each node uses a link state protocol to determine the current system topography, and then an optimization such as simulated annealing is run on the topography at each node, independently of the other nodes, to determine the optimum weak membership for use thereof in subsequent system operations. Since each node starts with the same random seed, the nodes all arrive at the same solution without having to communicate a common solution between nodes.
摘要翻译：一种用于解决可能包括冗余的节点系统中的弱隶属问题的系统和方法。给每个节点提供相同的随机种子。每个节点使用链路状态协议来确定当前的系统地形，然后在每个节点的独立于其他节点的地形上运行诸如模拟退火的优化，以确定在随后的系统操作中使用的最佳弱隶属度。由于每个节点以相同的随机种子开始，所以节点都到达相同的解决方案，而不必在节点之间通信一个共同的解决方案。

摘要： A data processing system comprises a master processor (10), a slave processor (30), a memory (50), and a bus subsystem (20) interconnecting the master processor (10), the slave processor (30), and the memory (50). The master processor (10) is configured to generate, in response to a memory access instruction, a read request comprising a read command for execution by the slave processor (30) to read data stored in a location in the memory (50) specified by the memory access instruction, and to write the read request to the slave processor (30) via the bus subsystem (20). The slave processor (30) is configured to execute the read command received in the read request from the master processor (10) to obtain the data stored at the specified location in the memory (50) and to write the data thus obtained to the master processor (10) via the bus subsystem (20).

摘要： A method for rebuilding meta-data stored in a data storage system (104) having storage devices (106) in which segments of data are located; for example, a storage system in the form of a log structured array. Data is written in segments to the storage devices (106) from a plurality of flows (122) of data and each segment of data contains meta-data relating to that segment. The meta-data stored in the storage system (104) can be rebuilt in the event of a failure by scanning the meta-data in each segment. A first scan of the meta-data in each segment in the storage devices (106) identifies the last segment written from each flow (122) and these segments are excluded from the rebuilding process as they may contain incomplete or inconsistent information. A second scan of the meta-data in each segment in the storage devices (106) identifies any segments which do not contain any live data tracks and these segments are also excluded from the, rebuilding process. The meta-data in the storage system (104) can then be rebuilt using the meta-data in the segments, excluding those segments identified.
摘要翻译：一种用于重建存储在数据存储系统（104）中的元数据的方法，所述数据存储系统（104）具有其中数据段被定位的存储设备（106）例如，以日志结构化阵列的形式的存储系统。从多个数据流（122）将数据分段写入存储设备（106），并且每个数据段包含与该段有关的元数据。存储在存储系统（104）中的元数据可以通过扫描每个段中的元数据而在发生故障的情况下重建。在存储设备（106）中的每个段中的元数据的第一扫描识别从每个流（122）写入的最后一个段，并且这些段从重建过程中排除，因为它们可能包含不完整或不一致的信息。在存储设备（106）中的每个段中的元数据的第二次扫描识别不包含任何实况数据轨道的任何段，并且这些段也被从重建过程中排除。然后可以使用段中的元数据来重建存储系统（104）中的元数据，不包括所识别的那些段。

摘要： A method is disclosed for reliably updating a data group in a read-before-write data replication environment. The method reliably updates the data group by receiving an updated data group sent from a first storage medium to a second storage medium, comparing the updated data group with a previous data group previously existing on the second storage medium and writing the updated data group to the second storage medium. The read-before-write and differencing method disclosed maintain reliability by storing multiple copies of changes made to the second storage medium during and after the write process.

摘要： Described is a method and apparatus for processing tasks in a data processing system including a microprocessor and an instruction cache. Tasks of different types are defined in the system with each task type having code associated therewith. The tasks are managed in a queue and are processed in order by loading the associated code into the instruction cache for execution on the microprocessor. The method comprises the steps of scheduling tasks of like type into a batch such that tasks in a batch are processed before processing the next ordered task. In the case where the code associated with a batched task fits within the instruction cache, the tasks in a batch can be processed without incurring the penalty associated with instruction cache misses.

摘要： A log structured array (LSA) controller apparatus controls the transfer of information between a processor and a plurality of information storage devices configured as an N+1 array in which the information is stored as stripes extending across the devices of the array, each stripe comprising N information strips and one parity strip, each information strip storing an integer number of logical tracks. The controller defines an LSA directory that specifies the location of each logical track in terms of the ID of the stripe to which the track belongs and the offset of the track within the stripe; wherein on the addition of an information storage device to the array, the additional strip provided for each stripe by the storage device is logically appended to the end of each stripe in the LSA directory.
