Embodiment 2

[0093] Embodiment 2 of the present invention provides another network card configuration method, such as image 3 As shown, the method specifically includes the following steps:

[0094] 301. The resource management center obtains a network card allocation request of an operating system running on a first CPU core.

[0095] Specifically, before the resource management center executes the method provided in this embodiment, the resource management center also needs to obtain the device information of each CPU core, and all device information on the device board (such as, each physical network card on the device board network card parameters, such as the network segment connected to the network card, bandwidth, network card characteristics, etc.), and before the first or every implementation of the method provided by this embodiment, a database (such as a device resource pool) needs to be established.

[0096] Optionally, before step 301, the following steps are also included: ...

Abstract

The present invention relates to the field of multicore processors. Provided are a network card configuration method and a resource management center, which solve the problem that a many-core decoupling based multicore processor system in the prior art cannot process data in a manner of crossing network cards and network segments. The method comprises: a resource management center acquires a network card allocation request of an operating system running in a first CPU core; the resource management center selects, according to a network parameter of a network service required by the operating system, a target physical network card satisfying the network parameter from M physical network cards; the resource management center separately selects at least one target hardware queue from each target physical network card; then, the resource management center sends an instruction message to a network card controller and receives queue information, fed back by the network card controller, of the target hardware queue; and finally, the resource management center sends the instruction message to a CPU controller in a CPU board. The present invention is used for constructing a virtual network card.

Description

technical field [0001] The invention relates to the field of multi-core processors, in particular to a network card configuration method and a resource management center. Background technique [0002] At present, in order to improve the parallel computing capability of multi-core processors and the performance of the multi-core processors, technicians have proposed the concept of many-core decoupling, that is, by combining memory, input / output (Input / Output, IO for short) in a multi-core computer system The decoupling of hardware devices such as equipment forms a network for managing hardware, thereby effectively improving the high-performance computing capability of the multi-core computer system. [0003] A typical multi-core processor system based on many-core decoupling that is commonly used now is composed of a CPU board integrated with multiple central processing units (Central Processing Units, referred to as CPUs), a device board integrated with various IO devices, a...
