Abstract

The invention relates to the field of big data processing, in particular to an adaptive task scheduling method and system and a retrieval method comprising the adaptive task scheduling method. The adaptive task scheduling method comprises the steps that according to the resource utilization condition and the load change condition of each working node, the working nodes adjust the weights of the nodes every certain period; and a task scheduling node reads the weight condition of each working node, ranks the weights, and performs task scheduling according to the rank of the weights. According tothe method, the cluster heterogeneity and the current resource remaining situation of the working nodes are considered, the problem of relative imbalance of calculation task allocation of the workingnodes is solved, the overall calculation capability of the system is improved, the overall task completion time is shortened, and the performance is improved.

Description

technical field [0001] The present application relates to the field of big data processing, in particular to an adaptive task scheduling method, system and retrieval method including the method. Background technique [0002] With the upgrading of equipment in major data centers, supercomputing centers, and Internet companies and the introduction of high-performance components (such as GPUs, etc.), each node in the cluster has gradually become heterogeneous. Different aspects of performance lead to differences in their processing capabilities. As a result, there are large differences in the comprehensive computing capabilities of each node, and the entire cluster is in a state of unbalanced resources. Due to the different capabilities of each node in the cluster, assigning the same task to different nodes will have different impacts on the node load. [0003] Spark's default task scheduling is that the spark task scheduler randomly selects some nodes from the registered wor...
