Abstract

The invention discloses a method, a device and a system for scheduling in a multiprocessor nuclear system and relates to the field of the multiprocessor nuclear system. The method, the device and the system can meet real-time network input / output (I / O) processing requirements so as to promote efficiency of the whole multiprocessor nuclear system. The method for scheduling in the multiprocessor nuclear system comprises obtaining a first control parameter, a second control parameter, a third control parameter and a fourth control parameter in an operation period of the multiprocessor nuclear system; transmitting data packages of data streams entering the multiprocessor nuclear system to an idle processor nucleus for processing according to the first control parameter, the second control parameter and the third control parameter; and switching the processor nucleus in the multiprocessor nuclear system between a cutting-off mode and a polling mode according to the fourth control parameter. The method, the device and the system are mainly used for processor nucleus scheduling.

Description

technical field [0001] The invention relates to the field of multi-processor core systems, in particular to a method, device and system for scheduling processor cores in a multi-processor core system. Background technique [0002] At present, services integrated on a multi-processor core system are gradually increasing, and network I / O (input / output, input / output) requests are also increasing day by day. The data processing ability of the multi-processor core system to the network I / O request becomes the key to the full performance of the system. In the prior art, a method for processing network I / O requests is: according to a statically configured processing mode, tasks are bound to specified processor cores for execution, or tasks are evenly allocated to relatively idle processor cores Another processing method is: according to the statically configured switching rules, the processor core is switched between the interrupt mode and the polling mode, thereby improving the p...
