摘要： In embodiments of a programming interface for data communications, a request queue and a completion queue can be allocated from a user-mode virtual memory buffer that corresponds to an application. The request queue and the completion queue can be pinned to physical memory and then mapped to kernel-mode system addresses so that the request queue and the completion queue can be accessed by a kernel-mode execution thread. A request can be received from an application for the kernel to handle data in the request queue, and a system issued to the kernel for the kernel-mode execution thread to handle the request. The kernel-mode execution thread can then handle additional requests from the application without additional system calls being issued.

摘要： Embodiments of the invention may improve the performance of multi-processor systems in processing information received via a network. For example, some embodiments may enable configuration of a system such that information received is distributed among multiple processors for efficient processing. A user may select from among multiple configuration options, each configuration option being associated with a particular mode of processing information received. By selecting a configuration option, the user may specify how information received is processed to capitalize on the system's characteristics, such as by aligning processors on the system with certain NICs. As such, the processor(s) aligned with a NIC may perform networking-related tasks associated with information received by that NIC. If initial alignment causes one or more processors to become over-burdened, processing tasks may be dynamically re-distributed to other processors.
