摘要： Once a search query is received from a user, a standard index is searched based on the search query. The standard index forms part of a set of replicated standard indexes having multiple instances of the standard index. A signal is then determined based on the search of the standard index. When the received signal meets predefined criteria, an extended index is searched. The extended index forms part of a set of extended indexes having at least one instance of the extended index. There are fewer instances of the extended index than instances of the standard index. Extended search results are then obtained from the extended index and at least a portion of the extended search results is transmitted towards a user.

摘要： A multi-processor computer system permits various types of partitions to be implemented to contain and isolate hardware failures. The various types of partitions include hard, semi-hard, firm, and soft partitions. Each partition can include one or more processors. Upon detecting a failure associated with a processor, the connection to adjacent processors in the system can be severed, thereby precluding corrupted data from contaminating the rest of the system. If an inter-processor connection is severed, message traffic in the system can become congested as messages become backed up in other processors. Accordingly, each processor includes various timers to monitor for traffic congestion that may be due to a severed connection. Rather than letting the processor continue to wait to be able to transmit its messages, the timers will expire at preprogrammed time periods and the processor will take appropriate action, such as simply dropping queued messages, to keep the system from locking up.

摘要： In general, systems and methods for identifying anomalous activity are described. For example, systems and methods are described, in which patterns of unusual behavior can be identified by aggregating logged, or sampled, data into cells and annotating each cell with statistically derived measures of how extreme the cell is relative to, for example, historical behavior of corresponding characteristics or relative to, for example, behavior of characteristics from a general population. Cells that have more than a predefined number of such annotations can be identified as anomalous and can be investigated by a user or outright acted upon in an automatic, pre-defined way.

摘要： A technique selectively imposes inter-reference ordering between memory reference operations issued by a processor of a multiprocessor system to addresses within a page pertaining to a page table entry (PTE) that is affected by a translation buffer (TB) miss flow routine. The TB miss flow is used to retrieve information contained in the PTE for mapping a virtual address to a physical address and, subsequently, to allow retrieval of data at the mapped physical address. The PTE that is retrieved in response to a memory reference (read) operation is not loaded into the TB until a commit-signal associated with that read operation is returned to the processor. Once the PTE and associated commit-signal are returned, the processor loads the PTE into the TB so that it can be used for a subsequent read operation directed to the data at the physical address.
摘要翻译：一种技术选择性地将由多处理器系统的处理器发出的存储器参考操作之间的参考间排序施加于与由翻译缓冲器（TB）错过流程程影响的页表项（PTE）相关的页面内的地址。 TB错误流被用于检索包含在PTE中的信息，用于将虚拟地址映射到物理地址，并且随后允许在映射的物理地址处检索数据。响应于存储器引用（读取）操作检索的PTE不会被加载到TB中，直到与该读取操作相关联的提交信号返回到处理器。一旦返回了PTE和相关联的提交信号，处理器将PTE加载到TB中，以便它可以用于针对物理地址的数据的后续读取操作。

摘要： A system and method is disclosed to maintain the coherence of shared data in cache and memory contained in the nodes of a multiprocessing computer system. The distributed multiprocessing computer system contains a number of processors each connected to main memory. A processor in the distributed multiprocessing computer system is identified as a Home processor for a memory block if it includes the original memory block and a coherence directory for the memory block in its main memory. An Owner processor is another processor in the multiprocessing computer system that includes a copy of the Home processor memory block in a cache connected to its main memory. Whenever an Owner processor is present for a memory block, it is the only processor in the distributed multiprocessing computer system to contain a copy of the Home processor memory block. Eviction of a memory block copy held by an Owner processor in its cache requires a write of the memory block copy to its Home and update of the corresponding coherence directory. No reads of the Home processor directory or modification of other processor cache and main memory is required. The coherence controller in each processor is able to send and receive messages out of order to maintain the coherence of the shared data in cache and main memory. If an out of order message causes an incorrect next program state, the coherence controller is able to restore the prior correct saved program state and resume execution.

摘要： A mechanism reduces the latency of inter-reference ordering between sets of memory reference operations in a multiprocessor system having a shared memory. The mechanism comprises a commit-signal that is generated by control logic of the multiprocessor system in response to an issued memory reference operation. The commit-signal facilitates inter-reference ordering; moreover, the commit signal indicates the apparent completion of the memory reference operation, rather than actual completion of the operation. The apparent completion of an operation occurs substantially sooner than the actual completion of an operation, thereby improving performance of the multiprocessor system.

摘要： When a search query is received, a plurality of partition indexes are searched using the set of search terms in the search query. Each partition index corresponds to a partition of a document index. The search of each respective partition index identifies a subset of a plurality of document index sub-partitions corresponding to the respective partition index. Next, the search query is executed by only those document index sub-partitions identified by the subsets, thereby identifying documents that satisfy the search query. By using the partition index to reduce the number of document index sub-partitions searched while executing a search query, the execution of the search query is made more efficient.
摘要翻译：当接收到搜索查询时，使用搜索查询中的搜索项集来搜索多个分区索引。每个分区索引对应于文档索引的分区。每个相应分区索引的搜索标识对应于相应分区索引的多个文档索引子分区的子集。接下来，搜索查询仅由由子集标识的那些文档索引子分区执行，从而识别满足搜索查询的文档。通过使用分区索引来减少在执行搜索查询时搜索的文档索引子分区的数量，使得搜索查询的执行更有效。
