Abstract

The invention discloses a task scheduling method and a task scheduling device. The method comprises the steps that a plurality of hyperthreads are grouped according to identifications of resources used by the plurality of hyperthreads running in a first processor core to obtain at least one hyperthread group, and in the at least one hyperthread group, the identifications of the resources used by the hyperthreads in the hyperthread group are the same; and according to the operation state parameters of one or more hyperthread groups in the at least one hyperthread group, changing a task operatedon at least one hyperthread in the plurality of hyperthreads, the operation state parameters comprising one or more of a load, a utilization rate, a competitive resource type and a resource density index. By the adoption of the task scheduling method and device, task scheduling can be achieved on the basis of the hyperthread groups obtained through resource sharing relation grouping, the problemthat tasks cannot be processed in time due to resource competition between the tasks is solved, and therefore the system performance is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a task scheduling method and a scheduling device. Background technique [0002] With the continuous development of computer technology, hyper-threading (Hyper-Threading, abbreviation: HT) technology is widely used, so that the processing performance of a central processing unit (Central Processing Unit, abbreviation: CPU) can be improved. The HT technology uses special hardware instructions to simulate a physical CPU into multiple logical CPUs, namely hyperthreads. The multiple hyperthreads run on the physical CPU and can use the resources of the physical CPU to perform multiple tasks. Therefore, multiple tasks can be executed in parallel on a hyperthread, so that more tasks can be executed on a physical CPU at the same time, which reduces the idle time of the CPU and improves CPU efficiency. However, multiple hyperthreads may share some resources in the CPU, such as...
