摘要： Methods and systems are described for applying the use of shards within a single memory address space. A database request is processed by providing the request from a client to a processor, the processor then distributing the request to multiple threads within a single process but executing in a shared memory address environment, wherein each thread performs the request on a distinct shard, and aggregating the results of the multiple threads being aggregated and returning a final result to the client. By parallelizing operations in this way, the request response time can be reduced and the total amount of communication overhead can be reduced.
摘要翻译：描述了在单个存储器地址空间内应用分片的方法和系统。数据库请求通过将来自客户机的请求提供给处理器来处理，然后处理器将请求分发到单个进程中的多个线程，但是在共享存储器地址环境中执行，其中每个线程在不同的分片上执行请求，以及聚合多个线程的聚合结果并将最终结果返回给客户端。通过以这种方式并行操作，可以减少请求响应时间，并且可以减少通信开销的总量。

摘要： Load balancing in a parallel database system is performed using multi-reordering, in which a sequence of multiple processors (two, three, or more) that have small average load (for example, the smallest of any such sequence) is selected to participate in load balancing. In the case of three adjacent low-load processors, the load of all three is evenly distributed over two of them, and the remaining processor becomes a free processor. The free processor is moved adjacent to a high-load processor, the load of which is then shared with the free processor. Data is moved in a “transaction” so that the view of data is always consistent. The database continues to service requests from a former location while data undergoes a transfer.
摘要翻译：使用多重排序来执行并行数据库系统中的负载平衡，其中选择具有小平均负载（例如，任何这样的序列中的最小的）的多个处理器（两个，三个或更多个）的序列参与负载均衡。在三个相邻的低负载处理器的情况下，所有三个负载均匀分布在其中两个处理器上，而剩余的处理器成为一个空闲处理器。免费处理器移动到高负载处理器附近，然后负载与免费处理器共享。数据在“事务”中移动，以便数据视图始终保持一致。数据库继续传输来自前一个位置的请求。

摘要： As described herein, a database machine is provided with specialized hardware that can be used to accelerate the sort function. This hardware lowers the computation cost of performing a raw sort operation over the result rows. The hardware may be embodied in a direct circuit (e.g., ASIC), a programmable circuit (e.g., FPGA), a parallel compute engine (e.g., GPU) or any parallel computer. A hardware-assisted sort procedure provides for the early return of up to K results. This early return feature is critically valuable in database operations because often an entire result set is not required. For requests that require only the first L results, when L

摘要： A vertical axis wind turbine has one or more blades (10) mounted in cantilever manner on a hub (12) on a short tower (14). The or each blade (10) is unsupported above the level of the hub (12) and extends freely upwards. The hub (12) may be a rigid mounting or a pivot mounting. If two blades (10) are used, they are desirably arranged in a crossed configuration so as to extend along a common axis. The upward arm of the blade (10) can be straight and rigid, or flexible, or cranked, or curved. The wind turbine is suitable both for land-based use and on water-going craft.
