摘要： Various technologies and techniques are disclosed for improving performance of parallel scans. Disk head randomization that occurs when performing a parallel scan is minimized by assigning a worker entity to each disk involved in the parallel scan, and by ensuring data is only accessed on a respective disk by the worker entity assigned to the disk. A parallel scan can be performed that is NUMA aware by ensuring a particular sub-set of data is resident in the same memory node during each parallel scan, and by ensuring the particular sub-set of data is processed by a worker entity assigned to a node in which the sub-set of data is resident. A process for performing a parallel scan involves breaking up work into sub-sets, assigning work to each worker entity that corresponds to a respective disk, and having the worker entities process the assigned work to complete the parallel scan.

摘要： An operating system is provided. The system includes an agent component to monitor computer activities between one or more single-item access components (SIAC) and one or more set-based access components (SBAC). An interface component is employed by the agent component to process kernel mode requests from a user mode application when communicating with a storage platform. Re-try components can be provided to facilitate cooperation between the SIAC and the SBAC.
摘要翻译：提供操作系统。该系统包括用于监视一个或多个单项访问组件（SIAC）和一个或多个基于组的访问组件（SBAC）之间的计算机活动的代理组件。当与存储平台通信时，代理组件使用接口组件来处理来自用户模式应用的内核模式请求。可以提供重新组合以促进SIAC与SBAC之间的合作。
