    • A system, method, and computer-readable medium that facilitate classification of database requests as problematic based on estimated processing characteristics of the request are provided. Estimated processing characteristics may include estimated skew including central processing unit skew and input/output operation skew, central processing unit duration per input/output operation, and estimated memory usage. The estimated processing characteristics are made on a request step basis. The request is classified as problematic responsive to determining one or more of the estimated characteristics of a request step exceed a corresponding threshold. In this manner, mechanisms for predicting bad query behavior are provided. Workload management of those requests may then be more successfully provided through workload throttles, filters, or even a more confident exception detection that correlates with the estimated bad behavior.
    • 提供了一种系统,方法和计算机可读介质,其基于所请求的估计处理特性,有助于将数据库请求分类为有问题的。 估计的处理特性可以包括估计的偏差,包括中央处理单元偏移和输入/输出操作偏移,每个输入/输出操作的中央处理单元持续时间和估计的存储器使用。 估计的处理特性是在请求步骤的基础上进行的。 响应于确定请求步骤的估计特性中的一个或多个超过相应的阈值,将该请求分类为有问题的。 以这种方式,提供了用于预测不良查询行为的机制。 那么这些请求的工作负载管理可以通过工作负载节流,过滤器或甚至与估计的不良行为相关的更自信的异常检测来更成功地提供。

    • A system, method, and computer-readable medium that facilitate efficient use of cache memory in a massively parallel processing system are provided. A residency time of a data block to be stored in cache memory or a disk drive is estimated. A metric is calculated for the data block as a function of the residency time. The metric may further be calculated as a function of the data block size. One or more data blocks stored in cache memory are evaluated by comparing a respective metric of the one or more data blocks with the metric of the data block to be stored. A determination is then made to either store the data block on the disk drive or flush the one or more data blocks from the cache memory and store the data block in the cache memory. In this manner, the cache memory may be more efficiently utilized by storing smaller data blocks with lesser residency times by flushing larger data blocks with significant residency times from the cache memory. The disclosed cache management mechanisms are effective for many workloads and are adaptable to various database usage scenarios without requiring detailed studies of the particular data demographics and workload.
    • 提供了一种有助于在大规模并行处理系统中有效使用高速缓冲存储器的系统,方法和计算机可读介质。 估计要存储在高速缓冲存储器或磁盘驱动器中的数据块的驻留时间。 根据居住时间的函数计算数据块的度量。 该度量还可以作为数据块大小的函数来计算。 通过将一个或多个数据块的相应度量与要存储的数据块的度量进行比较来评估存储在高速缓冲存储器中的一个或多个数据块。 然后确定将数据块存储在磁盘驱动器上或从高速缓存存储器刷新一个或多个数据块,并将数据块存储在高速缓冲存储器中。 以这种方式,通过用来自高速缓冲存储器的大量驻留时间冲洗较大的数据块,可以通过存储具有较小驻留时间的较小数据块来更有效地利用高速缓冲存储器。 公开的缓存管理机制对于许多工作负载是有效的,并且适用于各种数据库使用场景,而不需要详细研究特定数据人口统计特征和工作负载。

    • According to embodiments of the invention, rays may be stochastically culled before they are issued into the three-dimensional scene. Stochastically culling rays may reduce the number of rays which need to be traced by the image processing system. Furthermore, by stochastically culling rays before they are issued into the three-dimensional scene, minor imperfections may be added to the final rendered image, thereby improving the realism of the rendered image. Therefore, stochastic culling of rays may improve the performance of the image processing system by reducing workload imposed on the image processing system and improving the realism of the images rendered by the image processing system. According to another embodiment of the invention, the realism of images rendered by the image processing system may also be improved by stochastically adding secondary rays after ray-primitive intersections have occurred.
    • 根据本发明的实施例,射线可以在它们被发放到三维场景之前被随机地淘汰。 随机剔除光线可能减少图像处理系统需要追踪的光线数量。 此外,通过在将它们发布到三维场景之前随机剔除光线,可以将最小的缺陷添加到最终渲染图像,从而改善渲染图像的真实性。 因此,通过减少图像处理系统的工作量,提高图像处理系统所呈现的图像的真实性,可以提高图像处理系统的性能。 根据本发明的另一个实施例,图像处理系统呈现的图像的真实性也可以通过在发生光线原始交点之后随机添加二次光线来改善。
