摘要：
In this paper, a new dynamic load balancing decision algorithm is proposed based on the multi-core single-server of the domestic data processing system, and the data processing capability of the whole data processing system is improved by software algorithm. First, we set CPU affinity, which binds the process task on the CPU core to prevent inter-process migration. The weighted minimum join algorithm is then improved. According to the CPU occupancy of each CPU core, the load balancer set the weight of each CPU's processing power, the weight of the data packets are distributed to the task queue bound to the CPU with the largest weight, in order to achieve the load balance among different cores. Finally, the experiment proves that this dynamic load balancing decision algorithm can realize the load balance among the CPU cores of the system.
