Abstract

A method for dispatching multi-CPU includes dividing system task to be different subsets according to correlation between tasks, distributing different CPU into each task subset to for v CPU subset and task subset corresponding-combination then executing CPU dispatch according to different v CPU subset and task subset corresponding-combination.

Description

A Method of Multi-CPU Scheduling technical field The invention relates to the field of data communication systems, in particular to the technology of multi-CPU scheduling in the data communication system. Background technique In data communication products composed of multi-CPUs or multi-core CPUs that use tightly coupled shared memory, CPU resources are generally allocated in units of vCPUs (VirtualCPUs, that is, virtual CPUs) for task processing; in systems with more than 4 vCPUs, vCPUs Static allocation is generally used for allocation. Due to the complexity of the actual application of data communication equipment and the burstiness of data flow, static allocation of vCPUs will cause some processor resources to be idle, while some processor resources are too busy. The unbalanced nature of the system leads to the actual efficiency of the system is not high. Contents of the invention The technical problem to be solved by the present invention is to overcome the short...
